The Top Minor League Performers Of 2018

Over at Roster Resource, I rank Minor Leaguers throughout the regular season using a formula that takes into account several statistics with age and level serving as important factors in how they are weighed. These are not prospect rankings!

This is how it works:

  • Hitters are mostly rated by total hits, outs, extra-base hits, walks, strikeouts and stolen bases.
  • Pitchers are mostly rated by strikeouts, walks, earned runs, home runs and hits allowed per inning.
  • A few counting stats are included (IP, plate appearances, runs, RBI) to ensure that the players atop the list played a majority of the season.
  • The younger the player and the higher the level, the more weight each category is given. Therefore, a 19-year-old with an identical stat line as a 25-year-old at the same level will be ranked much higher. If a 23-year-old in Triple-A puts up an identical stat line as a 23-year-old in High-A, the player in Triple-A would be ranked much higher.

A player’s potential does not factor in to where they are ranked. If you’re wondering why a certain prospect who is rated highly by experts isn’t on the list, it’s likely because they missed time due to injury (see Victor Robles or Nick Senzel), MLB promotion (Juan Soto) or just weren’t productive enough. While there are plenty of recognizable names throughout the MiLB Power Rankings Top 200 list, it’s also full of players who were relatively unknown prior to the season and have seen their stock rise significantly due to their performance. Here’s a closer look at the Top 20.

1. Vladimir Guerrero Jr., 3B, Toronto Blue Jays Blue Jays Depth Chart

Guerrero probably deserved to start his MLB career sometime between the debuts of NL Rookie of the Year candidates Ronald Acuña Jr. (April 25th) and Juan Soto (May 20th). All things being equal, that would’ve been the case.

But his call-up was delayed, mostly because third baseman Josh Donaldson was healthy in May and designated hitter Kendrys Morales was being given every opportunity to break out of an early season slump. As Guerrero’s path to regular playing time was becoming clearer, he suffered a knee injury in early June that kept him out of action for a month. When he returned, the Jays’ playoff chances had dwindled. Instead of adding him to the 40-man roster and starting his service time clock, they chose to delay his MLB debut until 2019.

You can hate the rule, but I’m certain Jays fans would rather have Guerrero under team control in 2025 as opposed to having him on the team for a few meaningless months in 2018 and headed for free agency after the 2024 season. And maybe it’s just me, but I kind of enjoy seeing what kind of numbers a player can put up when he’s way too good for his competition. And all this 19-year-old kid did was slash .381/.437/.636 with 20 HR, 29 2B, 37 BB, 38 K in 408 plate appearances, mostly between Triple-A and Double-A (he had 14 PAs during a rehab stint in the low minors).  Thanks for providing us with that beautiful stat line, Vlad Jr.

2. Kyle Tucker, OF, Houston Astros Astros Depth Chart

Despite a slow start—he had 21 hits in his first 83 Triple-A at-bats with one homer and 20 strikeouts— the 21-year-old Tucker showed why the World Champions were willing to give him a chance to take their starting left field job and run with it in July.

Tucker wasn’t quite ready for the Big Leagues—he was 8-for-52 in two separate MLB stints prior to a recent third call-up—but his stock hasn’t dropped one bit after slashing .332/.400/.590 with 24 homers, 27 doubles and 20 stolen bases over 465 plate appearances in his first season at the Triple-A level.

3. Luis Rengifo, SS, Los Angeles Angels Angels Depth Chart

A 21-year-old shortstop just finished a Minor League season with 50 extra-base hits (7 HR, 30 2B, 13 3B), 41 stolen bases, as many walks as strikeouts (75 of each) and a .299/.399/.452 slash line. If the name Luis Rengifo doesn’t ring a bell, you’re probably not alone. He kind of came out of nowhere.

The Mariners traded him to the Rays last August in a deal for Mike Marjama and Ryan Garton. Nine months later, the Rays shipped him to the Angels as the PTBNL in the deal for C.J. Cron. Based on those two trades, I can say without hesitation that the Mariners and Rays did not think Rengifo was this good. Not even close.

4. Nathaniel Lowe, 1B, Tampa Bay Rays Rays Depth Chart

Lowe’s breakout season mirrors Juan Soto‘s in one way: They both posted an OPS above 1.000 at two different levels before a promotion to a third. Soto’s third stop was in Double-A, and it was a very short stint before heading to the Majors. After destroying High-A and Double-A pitching, Lowe’s final stop of 2018 was Triple-A, where he finally cooled off.

Still, the 23-year-old has put himself squarely on the Rays’ radar. After homering just 11 times in his first 757 plate appearances, all in the low minors, Lowe broke out with 27 homers and 32 doubles in 555 plate appearances in 2018. His overall .330/.416/.568 slash was exceptional.

5. Alex Kirilloff, OF, Minnesota Twins | Twins Depth Chart

We’re four seasons into the Byron Buxton and Miguel Sano era—both debuted during the 2015 season—and we can’t say for certain whether either player will even be penciled into the regular lineup in 2019. They could be still turn out to be perennial All-Stars someday. But you can’t blame Twins fans if they temper their expectations for the next great hitting star to come up through their farm system. And yet, that might be difficult with Kirilloff, a first-round draft pick in ’16, and last year’s No. 1 overall pick, Royce Lewis, after the year each of them just had. Both are moving up the ladder quickly.

The 20-year-old Kirilloff, who missed all of last season recovering from Tommy John surgery, was a hitting machine in his first full professional season. After slashing .333/.391/.607 with 13 homers in 65 games with Low-A Cedar Rapids, he hit .362 with seven homers and 24 doubles in 65 games with High-A Fort Myers. He also had 11 hits in the playoffs, including a 5-hit performance on September 5th.

6. Bo Bichette, SS, Toronto Blue Jays Blue Jays Depth Chart

All Bichette did during his age-20 season was hit 43 doubles and steal 32 bases while manning shortstop for the New Hampshire Fisher Cats, the 2018 Eastern League Champions. It’s unlikely that he’ll join Vlad Jr. in the Majors early next season, but he might not be too far behind.

7. Peter Alonso, 1B, New York Mets Mets Depth Chart

Alonso’s monster season (.975 OPS, 36 HR, 31 2B, 119 RBI between AAA/AA) ended in disappointment when he was passed over for a September promotion. As was the case with Vlad Jr., it didn’t make much sense to start his service time clock and fill a valuable 40-man spot during the offseason—neither Guerrero or Alonso have to be protected from the next Rule 5 draft—while the team is playing meaningless games. The 23-year-old Alonso did establish, however, that he is the Mets’ first baseman of the very near future, and they’ll plan accordingly during the upcoming offseason.

8. Touki Toussaint, SP, Atlanta Braves Braves Depth Chart

As tough as it will be to crack the Braves’ rotation in the coming years, the 22-year-old Toussaint has put himself in position to play a significant role in 2019 after posting a 2.38 ERA and 10.8 K/9 in 24 starts between Triple-A and Double-A. He’s also starting meaningful MLB games down the stretch as the Braves try to seal their first division title since 2013. After spending last October in the Arizona Fall League, where he followed up an underwhelming 2017 season by allowing 10 earned runs in 8 2/3 innings, he could find himself on the Braves’ playoff roster.

9. Vidal Brujan, 2B, Tampa Bay Rays Rays Depth Chart

The highest-ranked player to spend the entire season in Low-A, the 20-year-old Brujan slashed .320/.403/.459 while stealing 55 bases in his first crack at a full season league (27 games in High-A; 95 games in Low-A). He’ll still be overshadowed a bit in a deep Tampa Bay farm system that includes two of the best young prospects in the game, Wander Franco and Jesus Sanchez, but it’s hard to ignore such a rare combination of speed and on-base ability displayed by a switch-hitting middle infielder.

10. Michael King, SP, New York Yankees Yankees Depth Chart

The Yankees’ offseason trade that sent two MLB-ready players, Garrett Cooper and Caleb Smith, to the Marlins cleared a pair of 40-man roster spots prior to the Rule 5 draft and brought back $250K in international bonus pool money. They also received King, who—whether anyone expected it or not—was about to have a breakout season.

After posting a 3.14 ERA with a 6.4 K/9 over 149 innings in Low-A in his age-22 season, numbers that typically indicate “possible future back-of-the-rotation workhorse,”  he looks to be much more than that after his 2018 performance. In 161 1/3 innings across Triple-A, Double-A and High-A, King posted a 1.79 ERA, 0.911 WHIP and 8.5 K/9. He was at his best once he reached Triple-A, posting a 1.15 ERA with only 20 hits and six walks allowed over 39 innings.

11. Taylor Widener, SP, Arizona Diamondbacks Diamondbacks Depth Chart

Unlike the trade to acquire King, the Yankees appear to have gotten the short end of the stick in a three-team, seven-player offseason deal with Arizona and Tampa Bay. They traded away Nick Solak to the Rays and Widener to the Diamondbacks in exchange for Brandon Drury, who was supposed to fill a short-term need for infield depth.

While Drury was a bust in New York—he had nine hits in 51 at-bats before being traded to Toronto in a July deal for J.A. Happ—Solak, a second baseman/outfielder, put up terrific numbers in Double-A (.834 OPS, 19 HR, 21 SB) and Widener has emerged as one of the better pitching prospects in the game. The 23-year-old right-hander posted a 2.75 ERA, 2.8 BB/9 and 11.5 K/9 over 137 1/6 innings with Double-A Jackson.

12. Josh Naylor, 1B/OF, San Diego Padres Padres Depth Chart

The offseason signing of first baseman Eric Hosmer certainly didn’t bode well for Naylor’s future with the Padres. Whether he had an MLB future at all, however, was already in question. First base prospects can’t just be good hitters. They need to mash, which is far from what Naylor did in 2017 (.761 OPS, 10 HR between Double-A and High-A). But a 20-year-old holding his own in Double-A is still interesting, nevertheless. So it was worth paying attention when he hit .379 with seven homers, five doubles, 13 walks and 12 strikeouts in April. He also spent most of his time in left field in 2018, adding a bit of versatility to his game.

Although April was his best month, by far, he still finished with an impressive .297/.383/.447 slash line. He’ll enter 2019 as a 21-year-old in Triple-A who has flashed some power (17 HR, 22 2B in 574 plate appearances) and above-average plate discipline (64 BB, 69 K).

13. Eloy Jimenez, OF, Chicago White Sox White Sox Depth Chart

Unlike the Jays and Mets, who had multiple reasons to keep Guerrero and Alonso in the Minors until 2019, the Sox’s decision to bypass Jimenez for a September call-up was more questionable.

Already on the 40-man roster and without much to prove after slashing .337/.384/.577 with 22 homers and 28 doubles between Triple-A and Double-A, Jimenez’s MLB debut appeared imminent as September approached. But White Sox general manager Rick Hahn, citing Jimenez’s need to improve his defense, confirmed in early September that he would not be called up. Of course, the 21-year-old probably would’ve benefited greatly from playing left field in the Majors for 20-25 games in September. And, of course, Hahn is just doing a good job of not saying the quiet part out loud: Eloy under team control through 2025 > Eloy under team control through 2024.

14. Dean Kremer, SP, Baltimore Orioles Orioles Depth Chart

After posting a 5.18 ERA in 2017, mostly as a relief pitcher in High-A, Kremer’s stock rose quickly with a full-time move to the starting rotation in 2018. In 16 starts for High-A Rancho Cucamonga, the 22-year-old right-hander posted a 3.30 ERA with a 13.0 K/9. After tossing seven shutout innings in his Double-A debut, the Dodgers included him as a key piece in the July trade for Manny Machado. Kremer continued to pitch well with Double-A Bowie (2.58 ERA, 45 1/3 IP, 38 H, 17 BB, 53 K) and now finds himself on track to help a rebuilding Orioles’ team in 2019.

15. Nicky Lopez, SS, Kansas City Royals Royals Depth Chart

Lopez started to turn some heads during last offseason’s Arizona Fall League, and it carried over into 2018 as he slashed .308/.382/.417 with nine homers, 15 stolen bases and more walks (60) than strikeouts (52) between Triple-A and Double-A.  It’s a sign that the 23-year-0ld’s bat is catching up with his stellar defense and that he’s closing in on the Majors, where he could team with Adalberto Mondesi to form one of the better young middle infield duos in the game.

16. Royce Lewis, SS, Minnesota Twins Twins Depth Chart

The No. 1 overall pick in the 2017 draft didn’t disappoint in his first full professional season, posting an .853 OPS, nine homers, 23 doubles and 22 stolen bases in 75 Low-A games before a 2nd half promotion to High-A Fort Myers. He didn’t fare quite as well (.726 OPS, 5 HR, 6 SB in 46 games), but he did hit three homers in the playoffs to help his team win the Florida State League championship. It wouldn’t be a surprise if the if he reached Double-A early next season as a 19-year-old with a jump to the Majors in 2020 not out of the question.

17. Michael Kopech, SP, Chicago White Sox White Sox Depth Chart

Throwing a 100 MPH fastball isn’t as rare as it used to be, but Kopech has reportedly touched 105 MPH, putting him in a class of his own. Unfortunately, the 22-year-old right-hander is expected to join a long list of pitchers who have had their careers interrupted by Tommy John surgery after he was recently diagnosed with a torn UCL.

The timing isn’t great, as Kopech had just arrived in the Majors in late August and would’ve likely been a leading candidate for AL Rookie of the Year in 2019. Still, he’ll only have to prove that he’s back to full health before he returns to the Majors—he should be ready to return early in the 2020 season— after making a strong impression in Triple-A with a 3.70 ERA and 12.1 K/9 in 24 starts.

18. Kevin Smith, SS, Toronto Blue Jays Blue Jays Depth Chart

Not only do Guerrero, Bichette and Cavan Biggio likely form the best trio of infield prospects in the game, two are sons of Hall of Famers—Vladimir Guerrero Sr. and Craig Biggio, and Bichette’s dad, Dante, was also pretty good. And yet, another Blue Jays infield prospect with a very ordinary name and without MLB lineage managed to stand out. The 22-year-old finished the season with 25 homers, 31 doubles, 29 stolen bases and a cumulative .302/.358/.528 batting line between High-A and Low-A.

19. Gavin Lux, SS, Los Angeles Dodgers Dodgers Depth Chart

The former first-round pick wasn’t overly impressive in his first full Minor League season in 2017, slashing .244/.331/.362 with seven homers and 27 stolen bases for Low-A Great Lakes. A move to the hitter-friendly California League in 2018, however, seemed sure to give his offensive numbers a boost. It did. Lux had a .916 OPS and 41 extra-base hits in 404 plate appearances, but he also didn’t slow down once he reached the upper minors late in the year.

In 28 regular season games with Double-A Tulsa, the 20-year-old Lux slashed .324/.408/.495 with four homers in 120 plate appearances. It didn’t end there. Over an eight-game playoff run, the left-handed batter went 14-for-33 with five multi-hit games.

20. Patrick Sandoval, SP, Los Angeles Angels Angels Depth Chart

Acquiring the 21-year-old Sandoval from the Astros for free agent-to-be catcher Martin Maldonado could turn out to be the steal of the trade deadline. While the lefty didn’t stand out in Houston’s deep farm system, he was having a strong season at the High-A and Low-A levels at the time of the trade (2.56 ERA and 9.9 K/9 in 88 innings). The change of scenery didn’t affect him one bit as he tossed 14 2/3 shutout innings in the California League before finishing the season with four impressive Double-A starts (19 2/3 IP, 3 ER, 27 K).

Prospect Notes: Vlad, 2018 Draftees, Twins, Franco, Pitchers

With the season effectively over for all but a few teams, many front offices and fanbases alike are turning their sights toward the 2019 season and beyond as they hope for better days. With that in mind, here’s a look at some notes on some of the game’s top prospects from around the league…

  • ESPN’s Keith Law named Blue Jays third baseman Vladimir Guerrero Jr. his prospect of the year for a second consecutive season (subscription required), citing familiar questions about his long-term defensive capabilities but adding that there’s “zero question in my mind” that Guerrero is more than ready to thrive against Major League pitching at the moment. As for 2018 draftees, Cardinals third baseman Nolan Gorman and Royals lefty Daniel Lynch have been the two most impressive in his estimation. Gorman destroyed Appalachian League pitching and was promoted to full-season Class-A ball despite only having turned 18 in May. Lynch, a University of Virginia product, split his pro debut between those same two levels and pitched to a 1.58 ERA with a 61-to-8 K/BB ratio in 51 1/3 innings.
  • Jim Callis and Jonathan Mayo of MLB.com took a longer-term look at prospects yesterday, attempting to forecast who will be the top-ranked prospects this time a year from now. With names like Guerrero, Eloy Jimenez, Fernando Tatis Jr. and Kyle Tucker all expected to graduate from prospect lists next year, Callis and Mayo tab Twins shortstop Royce Lewis, the No. 1 overall pick from 2017, as their pick to be the game’s top prospect a year from now. More encouraging for Twins fans is that 2016 first-rounder and outfielder Alex Kirilloff, who missed the 2017 season due to Tommy John surgery, lands third on the same list after hitting .348/.392/.578 between Class-A and Class-A Advanced in his return from that surgery.
  • Meanwhile, Baseball America’s Kyle Glaser writes that Rays shortstop Wander Franco has been tabbed as BA’s breakout prospect of 2018. (Franco also appears on the previously mentioned lists from Law and MLB.com.) The 17-year-old Franco grew up living next to Indians superstar Jose Ramirez in the Dominican Republic and calls his childhood neighbor and friend his “idol” and greatest influence as a hitter. Glaser speaks to Franco about his relationship with Ramirez and his progress in 2018, and he also chats with Franco’s Appalachian League manager, Danny Sheaffer, about the young phenom’s strengths and upside. Franco was one of just two 17-year-olds playing in the Appy League this year but crushed older pitching to the tune of a .351/.418/.587 slash with 11 homers, 10 doubles and seven triples in 273 plate appearances.
  • Evaluating pitching prospects is among the most challenging endeavors for teams and online analysts alike. Kiley McDaniel of Fangraphs recently explored the pitfalls of attempting to do so, suggesting that many mainstream publications (his own past work at Fangraphs included) have leaned too heavily in favor of “power-over-feel” prospects and downplayed the potential significance of players cut from the Shane Bieber cloth — those who possess above-average command and stuff but perhaps not an overpowering arsenal of 60- or 70-grade offerings. McDaniel highlights Tigers righty Matt Manning, White Sox righty Dylan Cease and Rays lefty/first baseman Brendan McKay in examining the various elements that have contributed to this line of thinking in an interesting column that those who avidly follow prospects will want to check out in its entirety.

Joe Mauer Undecided On Playing Beyond 2018

Each one of Joe Mauer‘s nearly 8,000 career plate appearances has come in a Minnesota Twins uniform. The St. Paul native has said in the past in stating that he can’t see himself playing anywhere other than Minnesota if he’s to continue his career beyond the 2018 campaign — the final season of a franchise-record eight-year, $184MM contract. But while Mauer has previously said he’d like to continue playing, he took a more cautious approach in speaking with La Velle E. Neal III of the Minneapolis Star Tribune yesterday.

“There’s a lot [more] that goes into it than just, ‘Do you want to play?” Mauer replied when asked about continuing his career. “There’s a lot of different dynamics that go into it. I owe it to myself and my family to sit down and think about those things.”

Specifically, the 35-year-old Mauer goes on to cite yet another concussion that he suffered when making a diving attempt at a foul ball behind first base this past May, as well as the expected arrival of his third child this coming November. Mauer was well on his way to becoming one of the the best-hitting catchers in Major League history (and still can be considered as such, albeit over a shorter period than many expected) when a long-running series of concussions forced him out from behind the plate and began a decline in his offensive output.

To his credit, Mauer may have performed a bit better than some would expect since changing positions. He’s posted slightly above-average overall numbers at the plate (.276/.358/.387; 104 OPS+), including a particularly solid .305/.384/.417 slash last season. There’s no dodging the fact, though, that his bat hasn’t produced at anywhere near its once-elite levels. And while he quickly became a strong defensive first baseman,  that decline in offense is all the more glaring when considering the manner in which he moved down the defensive spectrum from catcher to first base.

None of that is to suggest that Mauer can’t still provide some value to the 2019 Twins (or, in the event of a dramatic shift in thinking, to another team). He’s turned in 10.3 wins above replacement from 2014-18, per Baseball-Reference (6.3, per Fangraphs). He’s also still a solid source of on-base percentage who rarely strikes out and is known for making opposing pitchers work (4.19 pitches per appearance — 14th-best in the Majors). That said, if he were to return for a 16th big league season, it would assuredly be at a significantly reduced rate.

As for whether the Twins’ front office would want him back, both chief baseball officer Derek Falvey and general manager Thad Levine expressed to Neal that they’re open to bringing the former No. 1 overall pick back in 2019.

“If he came with us with the question you posed, ‘I’d like to play another season, what does that look like?’ I think we’re rolling up our sleeves and having a conversation with him,” said Levine. Falvey added that Mauer has “earned the right to have that conversation at his own pace” and that the team “fully supports” Mauer’s preference to make that an offseason decision rather than one they’ll discuss in September.

In the event that Mauer does decide to hang things up, the Twins will have some internal options to replace him. Logan Morrison‘s $8MM mutual option will presumably be bought out following an injury-ruined season, but Tyler Austin has performed reasonably well since being traded over from the Yankees (.243/.313/.541 through 83 PAs). Miguel Sano has experience at first base and is likely better suited in the long run playing there than at third base. The free-agent market offers some potential platoon partners for Austin (e.g. Matt Adams), and the trade market, too, will present numerous options.

All of that cart-before-horse talk should be put on hold, however, as Mauer’s ultimate decision will undoubtedly impact the manner in which Falvey, Levine and the rest of the front office go about constructing a 2019 roster they hope can atone for a disappointing 2018 campaign in Minneapolis.

Ervin Santana Won’t Return This Season

Injured Twins right-hander Ervin Santana won’t return this season, Mike Berardino of the Pioneer Press tweets. The news doesn’t come as a surprise, as Minnesota’s out of the playoff race and Santana has barely pitched this season.

Long a quality starter, including as recently as 2017, Santana endured a horrid season that was cut short by nagging issues with his right middle finger. Santana underwent surgery on that finger in early February, and he was only supposed to miss 10 to 12 weeks. Instead, the 35-year-old didn’t make his 2018 debut with the Twins until July 25, and that ended up as one of just five major league starts he made this season. Santana, who hasn’t pitched since Aug. 16, will conclude 2018 with an unsightly 8.03 ERA/7.94 FIP, 5.84 K/9, 3.28 BB/9 and a 23 percent groundball rate in 24 2/3 innings.

Had he been his typical self this year, Santana would’ve been a strong candidate to return to Minnesota in 2019. Now, the Twins will have to decide on Santana’s $14MM option within the next few weeks, but it’ll be a shock if they don’t buy the veteran out and send him to the free-agent market. Not only did Santana struggle through an injury this year, but he took issue with the front office’s decision to sell earlier in the summer. Santana and the Twins seem to be heading toward a divorce, then. In the meantime, he’s undergoing three platelet-rich plasma injections in his finger, Beradino reports.

Jose Berrios Hires Wasserman Media Group

Twins righty Jose Berrios has hired the Wasseman Media Group to represent him, as Mike Berardino of the St. Paul Pioneer-Press reports.

Though he is not slated to reach arbitration eligibility this offseason, Berrios may still have some contractual matters to address with the Minnesota organization. He negotiated with the club last winter, though no deal was reached, and certainly could again be targeted for an extension over the offseason to come.

Berrios, 24, has now turned in two-straight solid campaigns in Minnesota after struggling in his 2016 debut. Through 28 starts in 2018, he owns a 3.92 ERA with 9.2 K/9 and 2.6 BB/9.

Those aren’t dominant numbers, to be sure, but Berrios arguably still has some untapped upside. He has boosted his swinging-strike rate to 11.1% this year, though he’s also permitting more home runs (1.29 per nine; 13.7% HR/FB) than he did last season.

As Berardino notes, Berrios would hardly be the first 2+ service-class pitcher to contemplate a long-term deal. There’s a long tradition of contracts for such hurlers, many of which have fallen in the same general price range and structure. Where Berrios fits in that line of precedent is up for debate — and, of course, negotiation.

Berrios had previously been a client of MDR Sports Management. MLBTR’s Agency Database has been updated to reflect his new representation.

AL Central Notes: Sano, Abreu, Duffy, Phillips

Twins slugger Miguel Sano had to be carted off the field Tuesday after suffering an apparent left leg injury upon sliding into second base (video link via MLB.com). That’s the same leg that caused Sano to miss the final few weeks of the 2017 season — an injury that ultimately led to surgery to insert a titanium rod into his shin. Initial x-rays on the injury were negative, according to the team, and Sano has been diagnosed with a bruised lower leg, although there figure to be further evaluations and updates after the game. Whether lingering effect from that offseason procedure have impacted Sano isn’t clear, but the 2018 campaign has been a nightmare for the former top prospect. A year after hitting .264/.352/.507 with 28 homers in 483 plate appearances, Sano has struggled to a dismal .202/.285/.405 slash with a 37.6 percent strikeout rate.

More news out of the AL Central…

  • White Sox first baseman Jose Abreu told reporters today that the surgery he underwent two weeks ago was to repair a testicular torsion, as Daryl Van-Schouwen of the Chicago Sun-Times writes. The issue “blindsided” Abreu and prompted emergency surgery, but the 31-year-old Abreu thankfully revealed that he is in good health and possibly even nearing a return to the playing field. Abreu expressed optimism about being able to play in a game this weekend, though Van Schouwen notes that both manager Rick Renteria and GM Rick Hahn offered a more cautious timetable and said Abreu could miss another week or so. For now, Abreu is doing light cardio exercises as he works his way back.
  • The Royals announced tonight that left-hander Danny Duffy exited tonight’s start with a shoulder impingement and shoulder tightness. Further details haven’t yet been made available, but Duffy already missed 10 days last month due to an impingement in his left shoulder, making continued symptoms all the more troubling. The 28-year-old lefty lasted just two-thirds of an inning and saw was charged with three runs, causing his ERA to balloon to 4.88 on the year. Center fielder Brett Phillips, meanwhile, was announced as day-to-day with a shoulder contusion after crashing into the outfield wall at top speed.

Twins Select Gregorio Petit

The Twins announced that they’ve selected the contract of infielder Gregorio Petit. In a corresponding move, the club transferred injured first baseman Logan Morrison to the 60-day disabled list.

Petit, 33, didn’t put up great numbers this season in Rochester, where he hit .268/.313/.327 with one home run over 312 PAs. He was somewhat more productive n a limited Twins stint earlier this year, with a .308/.400/.308 showing in 30 trips to the plate.

Over parts of six seasons in the majors, Petit carries a .253/.298/.350 slash in 456 plate appearances. His chief appeal lies in his defensive versatility. In that limited MLB action, Petit has appeared everywhere on the field except for behind the dish, on the mound, and in center field while spending most of his time as a middle-infielder.

Quick Hits: Buxton, Upton, Nationals, A’s

The Twins won’t be recalling Byron Buxton to the Major League roster, a decision that puts the team in line to gain an extra year of control over the young outfielder.  The situation has already created controversy, and there seems to be at least a chance that Buxton and his representatives at Jet Sports Management could look into filing a grievance with the league.  In a statement to The Athletic’s Ken Rosenthal (subscription required), agency owner B.B. Abbott said “We will examine this against the rights provided to all players under the CBA.  Until then, we will let Twins fans form their own opinions about this decision.”  MLBPA executive director Tony Clark also commented on Buxton, saying that the union “will review all options with Byron and his representatives.”

Minnesota GM Thad Levine did mention that the team was aware of Buxton’s service time circumstances, and Rosenthal is skeptical about the three larger factors (concerns about the wrist injury that sent Buxton to the DL, a lack of room in the Twins outfield, and “a performance standpoint factor“) that Levine cited as the chief reasons for Buxton remaining in Triple-A.  Buxton has not only been healthy enough to play regularly in Triple-A, Rosenthal observes, but the outfielder has also been hitting quite well in recent games.  Rosenthal wonders if the Twins’ desire to retain Buxton for an extra season will cost them in the long run, as Buxton may now be soured on signing a longer-term extension to remain in Minnesota beyond 2022.

Here’s more from around baseball on this Labor Day weekend…

  • Justin Upton suffered a concussion while avoiding a collision with Angels teammate Andrelton Simmons during Saturday’s game, the outfielder told MLB.com’s Maria Guardado and other reporters.  Upton came out of the game and didn’t play on Sunday, as he’ll be out of action until his symptoms fully subside.  Upton’s first full season in a Halos uniform has been an impressive one, as the 31-year-old has 26 homers and a .265/.349/.467 slash line over 533 plate appearances.
  • The Nationals will activate right-hander Erick Fedde from the 60-day DL to start Tuesday’s game, Mark Zuckerman of MASNsports.com writes.  Fedde has been sidelined with inflammation in his throwing shoulder, the latest in a series of injuries that has set back his young career.  Fedde has only 43 1/3 Major League innings to his name over 2017-18, though he’ll get a chance at showcasing himself in September.  As Zuckerman notes, the Nationals may use Gio Gonzalez‘s former rotation spot to give starts to multiple young arms, including Fedde and possibly Joe Ross, who is on track to make his return from Tommy John surgery sometime this month.
  • With the Athletics rolling, John Shea of the San Francisco Chronicle wonders why the team hasn’t extended manager Bob Melvin, who is only under contract through the 2019 season.  Failing to keep Melvin (or, for that matter, baseball operations head Billy Beane and GM David Forst) from “lame-duck status” in the final year of their deals threatens to undermine the progress that the A’s have made this season, Shea opines.  Back in June, the Chronicle’s Susan Slusser reported that there some belief that the team’s upper management wouldn’t retain Beane, Forst, and/or Melvin beyond the end of their current contracts.  If this was ownership’s plan, however, one wonders if things have changed in the wake of the Athletics’ hot streak and return to contention.

Heyman’s Latest: Machado, Yanks, Tribe, Harper, Realmuto, Braves, Mauer

Dodgers pending free agent Manny Machado has made it known he prefers shortstop, but the former Baltimore third baseman would return to the hot corner “for the right team,” Jon Heyman of Fancred writes. A willingness to play third certainly won’t hurt Machado on the open market, where he’s expected to sign one of the richest contracts ever, as it could encourage more teams to get involved in the bidding. Machado prefers to sign with the Yankees, Heyman relays, which jibes with a previous report from Bob Nightengale of USA Today. The Yankees already have an excellent shortstop in Didi Gregorius and a big-hitting rookie third basemen in Miguel Andujar, but their presences didn’t prevent the team from pursuing Machado at this year’s non-waiver trade deadline. Gregorius is only under contract for another year, moreover, while Machado is a much better defender at third than Andujar. Speculatively, if the Yankees sign Machado and extend Gregorius, perhaps they’d move Andujar to first base (where they haven’t gotten much production this year) or use him as trade bait to acquire pitching.

More rumblings from Heyman…

  • The Indians were the most aggressive pursuers of Nationals outfielder Bryce Harper at the non-waiver trade deadline in July, according to Heyman. However, the Indians were unwilling to trade high-end pitching prospect Triston McKenzie for Harper – who’ll be a free agent at season’s end – and general manager Mike Rizzo didn’t want to deal Harper anyhow. Expectations are that the Rizzo-led Nats will do their best to re-sign Harper, Heyman suggests.
  • There isn’t much optimism around baseball that the Marlins will be able to extend star catcher J.T. Realmuto, reports Heyman, who writes that he “apparently remains a target” of the NL East rival Braves. Atlanta extended catcher Tyler Flowers earlier this week, but only for a guaranteed $6MM over two years. Realmuto is also controllable for the next two seasons, and given that the Marlins won’t contend during that span, it seems like a strong bet that they’ll trade the 27-year-old if they’re unable to extend him.
  • Twins icon and pending free agent Joe Mauer is uninterested in playing elsewhere, per Heyman, who adds that it’s believed Minnesota would welcome the first baseman back in 2019. The question is whether the St. Paul native will choose to play next year, which would be his age-36 season. Mauer’s now in the final weeks of the franchise-record eight-year, $184MM extension he signed as a superstar catcher in 2010. The deal hasn’t quite worked out as hoped, though, thanks in part to injuries and a decline in production. Mauer has posted league-average offensive numbers over 444 PAs this year, with a .278/.350/.379 line (99 wRC+).
  • The Brewers finished second to the NL Central rival Cardinals in the race to sign then-free agent Miles Mikolas last winter, Heyman reports. A former Ranger and Padre, Mikolas returned stateside after a couple seasons in Japan, joining the Cardinals on a two-year, $15.5MM guarantee. That contract has been a steal for St. Louis, which has seen the 30-year-old Mikolas turn in 167 innings of 2.96 ERA/3.43 FIP ball this season.

AL Notes: Twins, Buxton, White Sox, Yankees, Boone

The Twins won’t recall center fielder Byron Buxton from Triple-A Rochester this season, in part because the left wrist issue he has been dealing with throughout the summer is “still lingering,” general manager Thad Levine said Saturday (via Dan Hayes of The Athletic; subscription required). But the decision to not bring the 24-year-old Buxton back to the majors this season is likely more related to his service time, suggests Hayes, who notes they’re now in position to control him through 2022 instead of 2021. Levine did acknowledge the service time as a factor, saying: “We wouldn’t be doing our jobs if we weren’t at least aware of service-time impacts on decisions we make.” Levine added Buxton’s agent is “displeased, disappointed for sure,” though the GM would like to “make amends” with Buxton at some point so as not to damage the sides’ relationship. At this time in 2017, Buxton was a cornerstone player for the playoff-bound Twins, potentially setting himself up for a lucrative extension.  A year later, he and the Twins have endured a year to forget. Injuries helped limit Buxton to a .156/.183/.200 line with no home runs and 28 strikeouts against three walks in 94 major league plate appearances. He was much better at Triple-A, hitting .272/.331/.456 with four HRs in 148 PAs, though he did post a 28.4 percent strikeout rate.

More from Minnesota and two other AL cities…

  • The White Sox have reinstated catcher Welington Castillo from the 10-day disabled list, putting him in position to play for the first time since May 23. Castillo landed on the DL with shoulder inflammation on Aug. 23, which came after he served an 80-game suspension for performance-enhancing drugs. Castillo, whom the White Sox signed to a two-year, $15MM contract last winter, began his season well before the suspension, as he hit .267/.309/.466 with six HRs in 123 PAs. While he was out, Chicago primarily turned to Omar Narvaez behind the plate, and he has quietly been among the game’s best offensive backstops this season (.284/.374/.432 in 264 PAs).
  • Major League Baseball has suspended Yankees manager Aaron Boone one game and issued  him an undisclosed fine stemming from his ejection on Friday, David Lennon of Newsday was among those to report. Boone, livid with home plate umpire Nic Lentz’s strike zone, was thrown out after a tirade in which the bill of his cap made contact with Lentz’s (video here). He’ll sit out Sunday’s game against Detroit, while bench coach Josh Bard will manage the Yankees.
  • With help from his family, just-acquired Twins catcher Chris Gimenez will decide in the offseason whether to continue his career, Mike Berardino of the Pioneer Press tweets. The 35-year-old journeyman has racked up 1,033 major league PAs since debuting in 2009, including 225 with Minnesota last season, though he has spent the majority of this season with the Cubs’ Triple-A affiliate.
