Blue Jays Promote Vladimir Guerrero Jr.
April 26: The Blue Jays have made Guerrero’s promotion official. His contract has been formally selected from Triple-A Buffalo, per a team announcement. Infielder Richard Urena was optioned to Triple-A to open a spot on the active roster.
April 24: It’s celebration time in Toronto. Blue Jays manager Charlie Montoyo announced to reporters following today’s game that the organization will promote uber-prospect Vladimir Guerrero Jr. to the Major Leagues on Friday (Twitter link via Ben Nicholson-Smith of Sportsnet). He’ll make his Major League debut in Friday’ series opener against the visiting Athletics.
The promotion for Guerrero comes after nearly a year of anticipation. Outcry for the organization to promote the vaunted young slugger began last year when he was utterly laying waste to Double-A pitching as a 19-year-old. Guerrero logged a laughable .402/.449/.671 slash in 266 plate appearances at the Double-A level before moving up to Triple-A where he posted a similarly ridiculous .336/.414/.564 slash. That otherworldly performance, at such a young age, unsurprisingly made Guerrero the No. 1 overall prospect on the rankings of Baseball America, MLBPipeline.com, Fangraphs and Baseball Prospectus.
Toronto, however, has been determined to push back Guerrero’s free agency as far as is reasonably possible. For Guerrero, that meant being passed over for a September call-up despite a dominant season in the upper minors, and it surely would have meant he’d open the season at Triple-A even were it not for an oblique injury that serendipitously gave the Jays an actual reason to keep him off the Opening Day roster.
Along the way, Jays leadership made the standard-issue vague claims about how Guerrero needed to work on his defense, his baserunning and learning to be the “best possible teammate” he could be while dodging persistent questions about manipulating Guerrero’s service time. It wasn’t even two months ago that general manager Ross Atkins made the questionable claim that he simply did “not see him as a Major League player” yet. (Guerrero, it seems, learned a lot in the 11 minor league contests he played this year.)
To be clear, the Blue Jays aren’t doing anything nefarious or against the rules; they’re exploiting a system that encourages them to make just this type of business-driven move in a year they’re not expecting to compete. The Cubs took this route with Kris Bryant, the Braves did so with Ronald Acuna Jr., and numerous other young stars have seen their arrival in the big leagues pushed back for similar reasons. It’s not a universal tactic, as evidenced by Eloy Jimenez, Pete Alonso and Fernando Tatis Jr., but it’s certainly a common one. Such service time machinations will continue to be a storyline so long as the current service time/arbitration system remains in place, though it’s possible that the league and the MLBPA will explore alterations as they work toward a new collective bargaining agreement beginning prior to the 2022 season.
Service time considerations aside, the promotion of Guerrero marks the beginning of a new era in Toronto. The majority of the core that brought the Jays to the ALCS in both 2015 and 2016 has since departed. Edwin Encarnacion, Jose Bautista, Josh Donaldson, David Price, Kevin Pillar, R.A. Dickey, Mark Buehrle, Marco Estrada and J.A. Happ have all landed elsewhere, and it’s likely that the Jays will look into moving each of Justin Smoak, Marcus Stroman and Aaron Sanchez this summer.
However, Guerrero is a potential cornerstone piece for the organization — one who’ll eventually be followed by the likes of Bo Bichette, Nate Pearson, Cavan Biggio and others as Toronto looks to lay a new foundation in the ever-competitive AL East. Other potential pieces of that puzzle have already begun to get a taste of the Majors, with Rowdy Tellez, Danny Jansen and Lourdes Gurriel Jr. all receiving some experience at the game’s highest level.
The position played by Guerrero in the long term is far from set in stone. While the claim that Guerrero’s need for defensive improvement was the reason for keeping him in the minors was never legitimate, questions about his glovework are valid. Scouting reports have long pegged him as a sub-par option at third base, and it’s possible he’ll have to slide across the diamond to first base or even settle in as a primary designated hitter at some point in his early or mid 20s. The Jays surely hope that his defense can improve with some help from the big league coaching staff and continued reps in the Majors, but the 6’2″, 250-pound Guerrero may simply not be a long-term option at his natural position. Regardless of his defensive upside (or lack thereof), though, Guerrero’s prodigious bat should quickly establish him as one of the game’s brightest young stars.
Given the timing of his promotion, Guerrero will be under control for the Blue Jays through at least the 2025 season, although it’s possible that the Jays will explore the same type of early-career extension the White Sox were able to achieve with Jimenez (if they haven’t already begun to do so). Guerrero will be a slam-dunk Super Two player, assuming he’s not optioned back to the minors at any point, as he’ll finish out the 2019 campaign with 158 days of service.
Nationals Promote Carter Kieboom
April 26: The Nats have formally announced the move. Righty Koda Glover was transferred from the 10-day injured list to the 60-day injured list to open a spot on the 40-man roster.
April 25, 5:59pm: Infielder Jake Noll is in the lineup for the Nationals’ Triple-A affiliate tonight, indicating that he’ll be a corresponding 25-man roster move. The Nats will still need to clear a 40-man roster spot for Kieboom.
4:52pm: The Nationals will promote top infield prospect Carter Kieboom prior to Friday’s series opener against the Padres, reports Jesse Dougherty of the Washington Post. Kieboom, a top 50 league-wide prospect in the eyes of Baseball America, MLB.com, Baseball Prospectus, Fangraphs and ESPN, is not on the Nationals’ 40-man roster. A corresponding move to fit him onto the roster will be necessary.
Kieboom, 21, was Washington’s top pick (No. 28 overall) in the 2016 draft. He’s hit at every level throughout his quick ascension to the big leagues, though the torrid start he’s enjoyed thus far in his first exposure to Triple-A pitching is his best work yet. Through 83 plate appearances, Kieboom has crushed opponents with a .379/.506/.636 batting line, three homers, six doubles and a triple. Since being drafted, Kieboom is a combined .286/.373/.471 hitter across all levels at which he’s played — despite the fact that he has consistently been hitting against older, more experienced pitchers.
The exact manner in which the Nationals will utilize Kieboom is not yet clear, but it stands to reason that if the Nats are calling him up this early, the plan is for him to get regular at-bats. Kieboom is a shortstop by trade but has split his time between both middle-infield positions this season. The Nats are without Trea Turner for what figures to be another couple of weeks and have been starting the light-hitting Wilmer Difo in his place, but third baseman Anthony Rendon has also been banged up and out of the lineup for a few days. Offseason signee Brian Dozier has yet to hit much, but he’ll presumably be given a longer leash to get things right.
Though the Nationals’ infield is crowded with veterans when at full strength, they’ve shown a willingness to promote prospects early in the past and carry them for the duration of the season — as was the case with Rookie of the Year runner-up Juan Soto last season. Kieboom has a long way to go before forcing the organization’s hand in that same manner, but if he’s up in the big leagues for good, the Nationals would be able to control him through the end of the 2025 season (though he’d be a slam dunk Super Two player in arbitration).
Red Sox Place Eduardo Nunez On IL, Promote Michael Chavis, Designate Erasmo Ramirez
The Red Sox announced a series of roster moves Friday morning, revealing that they’ve placed Eduardo Nunez on the 10-day injured list (retroactive to April 18) due to a mid-back strain). Additionally, Boston has designated righty Erasmo Ramirez for assignment and recalled infielders Tzu-Wei Lin and Michael Chavis from Triple-A Pawtucket. It’ll be the MLB debut for Chavis, a former first-round pick who is currently ranked as the game’s No. 75 overall prospect by MLBPipeline.com.
Nunez will join fellow second basemen Dustin Pedroia and Brock Holt on the injured list. There’s no word yet on long he’s expected to be sidelined. The loss of that trio facilitated the promotion of Chavis for his first look in the big leagues as well as the return of the versatile Lin, who has been up and down with the Sox dating back to the 2017 season. While Chavis has been primarily a third baseman in his minor league career, he’s played 47 innings at second base in 2019 and has experience at shortstop in the past, as well. He seems likely to step up at second base for the time being with Boston’s other options on the mend.
Selected with the 26th overall pick in the 2014 draft, Chavis posted modest numbers in his first two and a half professional seasons before breaking out with a .282/.347/.563 batting line between Class-A Advanced and Double-A in 2017. He followed that up with a similarly impressive .298/.381/.538 slash across three levels in 2018 (topping out in Triple-A but spending the bulk of his time in Double-A), though it should be pointed out that Chavis’ 2018 campaign was shortened by an 80-game PED suspension.
This season, he was off to a .250/.354/.600 start in Pawtucket. Chavis is a bat-first prospect, drawing the most praise for plus raw power and a solid hit tool. Strikeouts are part of his game but haven’t been a huge problem for him, and he’s shown improved plate discipline in recent years as well.
Ramirez’s stint with the Sox will go down as a brief and forgettable one. The veteran right-hander made only one appearance with the Boston organization, allowing four runs on four hits (including a pair of homers) and a walk with one strikeout in three inning of relief. The Red Sox will have a week to trade him, release him or pass him through outright waivers; Ramirez would be able to reject an outright assignment in favor of free agency anyhow, so this move seems quite likely to end his tenure with the Red Sox organization.
Though he had a poor year with the Mariners in 2018, Ramirez isn’t far removed from a three-year stretch (2015-17) in which he logged a combined 3.97 ERA with 7.0 K/9, 2.3 BB/9 and 1.2 HR/9 in 385 1/3 innings between Tampa Bay and Seattle. He has extensive big league experience as both a starter and reliever, and a club looking at adding some depth in either area could take a look at the righty, who won’t turn 29 until early next month. The Braves are known to be on the lookout for potential bullpen arms, for instance, while the Rangers haven’t been secretive about their desire to add rotation depth.
Mets To Select Contract Of Pete Alonso
The Mets are preparing to select the contract of first base prospect Pete Alonso, according to Anthony DiComo of MLB.com (via Twitter). He’ll make the Opening Day roster — a possibility that grew throughout camp and that Jon Heyman of MLB Network tweeted recently was slated to take place.
Alonso’s path to the roster was cleared by injuries to Todd Frazier and Jed Lowrie, but he may have forced his way up regardless. The 24-year-old has slugged his way up the prospect charts in recent years, drawing top-50 consensus rankings from prospect hounds after the 2018 season. He continued to drive the ball this spring, turning in a .368/.394/.647 slash with four home runs in 71 plate appearances against Grapefruit League pitching.
When it comes to prospect promotions, service time is always a major consideration. Even those players who are deemed ready for the big leagues and necessary for the roster may beheld down briefly to ensure they do not secure a full season of MLB service. Those considerations were no doubt part of the equation when Alonso failed to receive a September call-up last year.
In this case, though, there’s arguably not much reason for the Mets to stay their hand. First and foremost, Alonso is a 24-year-old first baseman who has played a full year in the upper minors — not, say, a 20-year-old shortstop who’s considered one of the very best prospects in baseball. Even if Alonso is never sent back down, the club will control him throughout his twenties.
Alonso’s age-30 season could well be a valuable one, but it’s not nearly so precious as the extra season might be for some other top prospects. That’s particularly true since hitter’s aging curves are hewing younger and toward a consistent downward trajectory. Alonso is a player whose value is expected to come more or less exclusively from his bat, so it’s all the more sensible to go ahead and bring him up. And if he doesn’t produce from the outset, or the roster situation otherwise demands it, the club can always shuttle him back to Triple-A and gain back that added year of control.
It’ll certainly be fun to see Alonso take the field alongside the many other new faces in New York and the rest of the NL East. The division promises to be a battle all year long. His ability to thrive out of the gates could have a meaningful impact for a club that doesn’t know whether or when it’ll see Yoenis Cespedes in its lineup.
Since he was drafted in the second round in 2016, Alonso has steadily produced in just over a thousand plate appearances of professional action. He’s a .290/.381/.560 hitter in the minors, with 59 total home runs (including 36 in the 2018 season) and 114 walks to go with 221 strikeouts. That’s a rather well-rounded profile, though power remains the calling card.
Defense and baserunning will likely never be strong suits, but the hope is that Alonso will hit enough that those factors will largely fade to the background. There aren’t really any major concerns with the bat, but his track record isn’t flawless. Even as he reached new power heights last year at Triple-A, Alonso’s strikeout rate popped up to 25.9%. He still managed a double-digit walk rate at the highest level of the minors, but the on-base outlook still comes with some uncertainty. Alonso will need to maintain a high batting average (as he did until ascending to Triple-A) or boost his walk rate to be a truly outstanding offensive producer.
Yankees Promote Justus Sheffield
The Yankees have promoted one of the game’s best pitching prospects, left-hander Justus Sheffield, from Triple-A Scranton, Conor Foley of the Scranton Times-Tribune reports. Sheffield’s not on the Yankees’ 40-man roster, which is full, so they’ll need to create space for him.
Sheffield entered the professional ranks as a 2014 first-round pick of the Indians, who chose him 34th overall, but only lasted a couple years in the organization. The Tribe, hoping to win a World Series in 2016, dealt a package including Sheffield, outfielder Clint Frazier and lesser pieces to the Yankees for star reliever Andrew Miller at that July’s non-waiver trade deadline. Miller nearly helped the Indians to a title after the trade, but they fell in seven games to the Cubs in the Fall Classic that season.
Sheffield was a well-regarded prospect when Cleveland sent him to New York, and that remains the case. The 6-foot, 200-pounder ranks as the majors’ 22nd-best prospect at Baseball America (subscription required), while both MLB.com (No. 27) and FanGraphs (No. 50) are among other prominent outlets that are bullish on him. In their free scouting report, Jim Callis and Jonathan Mayo of MLB.com note that the 22-year-old Sheffield may end up with three “plus” offerings – a 92 to 97 mph fastball, a slider that sits in the mid-80s and a changeup – and add that he has the potential to emerge as a No. 3 starter in the majors.
Sheffield has impressed as a starter in the minors, including this season at Scranton, where he logged a stingy 2.56 ERA/3.13 FIP with 8.59 K/9, 3.68 BB/9 and a 44.9 percent groundball rate in 88 innings. But the Yankees did recently prepare Sheffield to work as a reliever upon his first big league promotion, and he may fill that role in the coming weeks. After all, with Luis Severino, Masahiro Tanaka, J.A. Happ, C.C. Sabathia and Lance Lynn, the Yankees currently have a set rotation, and that group will shrink if the Bombers get past the AL West runner-up in the wild-card round and advance to the ALDS.
While Sheffield looks like a potential reliever for the Yankees right now, he may have a shot to win a spot in their rotation in 2019. The only two members of the Yankees’ starting staff who are sure to return next season are Severino and Tanaka. Happ, Sabathia and Lynn are set to become free agents, and there aren’t any obvious in-house replacements on hand beyond Sheffield. Fellow youngsters Domingo German – whom the team’s recalling from Scranton, per Foley – and Jonathan Loaisiga have struggled in the majors this season, while Jordan Montgomery will miss a large portion of 2019 after undergoing Tommy John surgery in June. Therefore, the door could be open for Sheffield, who ranks as the Yankees’ No. 1 prospect at Baseball America and MLB.com.

Padres To Promote Francisco Mejia
The Padres are set to promote top prospect Francisco Mejia from Triple-A El Paso, per Dennis Lin of The Athletic (Twitter link). MLB.com’s AJ Cassavell adds that while Mejia could eventually be shifted back and forth between catching and the outfield, he’s been catching in El Paso this season and will be used as a catcher in the month of September with the Padres.
Mejia, 22, was the lone prospect traded from Cleveland to San Diego in the July deal that sent both Brad Hand and Adam Cimber to the Indians. He’s long rated as one of the game’s top overall prospects and entered the 2018 campaign as a consensus top 20 all-around minor leaguer. While he had a solid but unspectacular run with the Indians’ Triple-A affiliate this season, he’s exploded for a .328/.364/.582 slash with seven homes, eight doubles and a triple in just 132 PAs with the Padres’ top affiliate since the trade.
The arrival of Mejia in San Diego will give the Padres a pair of catchers who were highly touted as prospects, though certainly Austin Hedges‘ bat remains a work in progress. Hedges has improve upon last year’s overall production but is still hitting just .239/.292/.422 through 271 trips to the plate in 2018. Hedges is regarded as a premier defender behind the dish, though, even if his 22 percent caught-stealing rate is uncharacteristically low in 2018. The 26-year-old ranks as one of the game’s better pitch framers and sits 10th among MLB catchers in Baseball Prospectus’ Fielding Runs Above Average this season, even in spite of his unusual throwing troubles.
The San Diego front office likely views the presence of both Hedges and Mejia as a good problem to have. Neither will be expensive in 2019. Mejia, of course, will be a pre-arbitration player while Hedges will receive a small but notable bump in pay as a Super Two player in arbitration. It’s possible that the pair could shoulder the bulk of the Padres’ work behind the plate for years to come, with Hedges serving as a glove-first option with power but middling OBP skills, while Mejia provides a bat-first option with a terrific arm but a lesser all-around defensive reputation.
Mejia does already have a slight bit of MLB experience under his belt, having logged 12 games with the Indians from 2017-18 (just one this year). He’s totaled just over a month of big league service time and will finish out the season with roughly 60 days of big league service. That’ll keep him from reaching Super Two status in arbitration if he’s in the big leagues to stay. Currently, he projects to reach arbitration eligibility following the 2021 season, and he’d reach the open market as a free agent following the 2024 season. Further time spent in the minors could yet push that trajectory back, but it appears that he’ll be given the opportunity to prove that he’s learned all he has to learn at the minor league level.
Pirates Promote Kevin Kramer, Designate Buddy Boshers
The Pirates announced several September call-ups today, designating lefty Buddy Boshers to create roster space. Pittsburgh selected the contract of well-regarded middle-infield prospect Kevin Kramer along with that of journeyman catcher Ryan Lavarnway.
Also heading up to the majors are a series of players who already possessed 40-man roster spots. Righties Tanner Anderson, Michael Feliz, and Clay Holmes will all join the organization for the stretch run, as will outfielder Jordan Luplow.
Kramer will join Kevin Newman, another talented young infielder seen as part of the future, on the MLB roster. Chosen in the second round of the 2015 draft, Kramer is viewed as a solid all-around player. Certainly, he has impressed in the upper minors in the past two seasons, turning in identical 141 wRC+ figures in an injury-shortened 2017 at Double-A and in a full campaign this year at Triple-A.
In his 527 plate appearances with Indianapolis in 2018, Kramer owns a .311/.365/.492 slash with 15 home runs and 13 steals. He has spent some time at shortstop in the minors, but the bulk of his innings of come at second base and that’s where he’s expected to play in the big leagues.
As for Boshers, the 30-year-old southpaw has seen time in three MLB seasons but didn’t make it up in 2018. He has worked to a 3.32 ERA with 9.8 K/9 and 2.8 BB/9 in his 57 frames at Triple-A, with time spent at both the Bucs’ and Astros’ top affiliates.
Braves Promote Kyle Wright
The Braves announced several roster moves Saturday, including the promotion of right-handed pitching prospect Kyle Wright, whom they selected from Triple-A Gwinnett. The club also transferred closer Arodys Vizcaino to the 60-day disabled list and selected outfielder Lane Adams‘ contract from Triple-A. Meanwhile, injured righty Brandon McCarthy re-aggravated his right knee during a rehab assignment and did not come off the 60-day DL, Gabe Burns of the Atlanta Journal-Constitution reports.
There’s a lot to unpack here, though the most exciting news for Atlanta is the addition of Wright. The ex-Vanderbilt standout entered the 2017 draft as a potential No. 1 pick, but he fell to No. 5, leading the Braves to scoop Wright up and sign him to a then-record bonus worth $7MM. Wright has made good on that pick by emerging as one of the majors’ elite pitching prospects, evidenced in part by MLB.com ranking him as the game’s 24th-best farmhand. The 22-year-old is set to become the latest highly promising Braves hurler to debut in 2018, joining the now-injured Mike Soroka, Touki Toussaint and Kolby Allard.
While Wright has a chance to eventually emerge as a high-end starter, he’ll work out of the playoff-contending Braves’ bullpen down the stretch, per Burns. Wright did make three relief appearances out of seven at the Triple-A level this year, but he has primarily served as a starter in 2018. Across 27 appearances and 24 starts between Double-A and Triple-A this season, Wright pitched to a 3.46 ERA with 8.7 K/9 and 3.3 BB/9.
Elsewhere in the Braves’ bullpen, Vizcaino’s move to the 60-day DL looks discouraging on the surface, but he’s still likely to make it back in 2018, manager Brian Snitker told Burns and other reporters on Saturday. Vizcaino had been on the 10-day DL since July 14 with right shoulder troubles, so he’s now ineligible to return until mid-September. His absence has paved the way for lefty A.J. Minter to close for the Braves, and the latter has converted 11 of 13 saves while notching a 3.12 ERA with 10.21 K/9 against 2.94 BB/9 in 52 innings this season.
While the the latest development regarding Vizcaino isn’t ideal, McCarthy’s setback is downright discouraging, as it’s now possible he has thrown his last major league pitch. McCarthy, who hasn’t taken a major league mound since June 24, announced earlier this month that he plans to retire at the end of the season. The 35-year-old has started in all 15 of his appearances this season, but he was set to finish the year as a reliever upon his return.
Adams, whom the Braves signed to a minors pact in mid-July, saw action with them earlier season and last year, totaling 143 plate appearances and batting a respectable .270/.345/.460. The 28-year-old was out of the Atlanta organization for a brief period in 2018, though, as he elected free agency in late April and then latched on with the Cubs. But Adams struggled with Chicago’s top minor league affiliate before rejoining Gwinnett, with which he hit an unappealing .191/.238/.266 with no home runs in 101 PAs this season.
Padres Promote Luis Urias
Aug. 28: The Padres have formally announced Urias’ promotion to the Majors. Asuaje has been optioned to Triple-A to open a spot on the active roster. San Diego has also placed lefty Clayton Richard on the 10-day disabled due to inflammation in his left knee and activated right-hander Colten Brewer from the disabled list in his place.
Aug. 27: The Padres are set to promote highly regarded infield prospect Luis Urias, according to Kevin Acee of the San Diego Union-Tribune. He is expected to debut tomorrow.
Urias, 21, is widely considered one of the crown jewels of a Padres system that, the organization has long hoped, will usher in a golden age of baseball in San Diego. There’s a clear consensus that he’s one of the most promising young players in baseball, with outlets such as Fangraphs (#22), MLB.com (#22), and Baseball America (#29) rating him among the game’s thirty or so best prospects.
There’s a lot to like about Urias’s potential as a hitter. He features a rare combination of plate discipline and contact ability that has allowed him to hit over .300 while carrying nearly a .400 OBP over his five minor-league seasons. Power isn’t a strong suit, though Urias has increased his home-run output over recent campaigns and this year has put the ball over the fence eight times in 533 plate appearances.
It seems fair to note, too, that Urias has the kind of underlying skills that could allow him to come into more power at the game’s highest level. In recent years, we’ve seen several players — Jose Altuve, Francisco Lindor, and Jose Ramirez among them, to take a few famous examples — develop surprising pop after reaching the bigs. Whether or not Urias is destined for that kind of outcome obviously isn’t yet known, but it seems notable that MLB.com credits him with more raw power than his outcomes indicate while BA cites Urias’s impressive exit velocity.
To be sure, Urias would likely generate even greater excitement if he was considered a future shortstop. Still, he is also valued for his defensive potential. Most evaluators indicate that he’ll likely be a high-quality defender at second base. It doesn’t hurt that he’s considered at least capable of playing shortstop as well; indeed, Acee says that Urias will get some time there upon his arrival.
For the Padres, this promotion offers an opportunity to get a look at a player who’s expected to hold down an important role for years to come. Urias will not accrue enough service time this year to put himself on track for future Super Two status. If he stays in the majors from here on out, he won’t be eligible for free agency until at least 2025. Picking up thirty-plus days of MLB action will make it a bit harder for the Friars to hold Urias down to open the 2019 season in hopes of extending the team’s control rights.
If he shows well upon his arrival, Urias will likely enter camp next year as the odds-on favorite to open the season as the regular second baseman. San Diego has not received much production from its options at the position thus far in 2018, after all, so the organization is no doubt anxious to plug in a permanent piece. Jose Pirela, Carlos Asuaje, and Cory Spangenberg have all failed to take advantage of opportunities at second this season.

White Sox To Promote Michael Kopech
The White Sox will promote top pitching prospect Michael Kopech on Tuesday, the team announced on its official Twitter feed. The 22-year-old right-hander will make his Major League debut in a start against the Twins.
Picked 33rd overall by the Red Sox in the 2014 draft, Kopech was already considered one of the game’s top young arms when Boston dealt him as part of the blockbuster prospect package sent to Chicago in exchange for ace southpaw Chris Sale in December 2016. Kopech made his Double-A and Triple-A debuts in the White Sox farm system, and he has posted a 3.63 ERA, 11.9 K/9, and 2.88 K/BB rate over 141 1/3 innings at the Triple-A level.
Those numbers also include some control issues, such as a 4.3 BB/9 this season, and Kopech’s 2018 season has been marred by a few rough outings. Kopech recently discussed his year with The Athletic’s James Fegan, which has seen him deal with some off-the-field tragedy while also working on such mechanical issues as a new grip for his changeup, and a slower delivery. His delivery was cited as a concern in scouting reports from both MLB.com and Baseball America, with BA noting that Kopech’s delivery is a reason for “his below-average command and control.”
Still, despite these issues, both MLB.com and Baseball America ranked Kopech as the 13th-best prospect in baseball due to his massive potential. (Fangraphs also had him 16th on their updated top-100 prospect rankings, with ESPN’s Keith Law ranking Kopech 11th and Baseball Prospectus ranking him 17th in their preseason top-100 lists.) If Kopech is able to refine his changeup, it would be his third pitch to go along with a slider that MLB.com calls a “plus-plus offering as its best,” as well as Kopech’s signature pitch, a blazing fastball. Kopech has cracked triple digits with his heater and regularly throws it in the 96-99mph range.
Kopech has long been considered one of the jewels of the White Sox rebuild, and the decision to promote him at this point means that he’ll get an audition towards becoming a regular rotation member in 2019. With Kopech now reaching the big leagues, it only creates more anticipation towards the potential debut of Chicago’s top prospect, slugger Eloy Jimenez.
