Keynan Middleton

White Sox Sign Keynan Middleton To Minor League Deal

By | at

The White Sox have signed right-hander Keynan Middleton to a minor league deal, according to his transactions tracker at MLB.com. He’ll presumably receive an invitation to major league Spring Training.

Middleton, 29, was drafted by the Angels and spent the first few seasons of his career there. He seemed to be establishing himself as a quality relief option in 2017 and 2018, making 80 appearances over those two seasons with a 3.43 ERA. Unfortunately, he required Tommy John surgery midway through the latter campaign, putting him out of action for over a year.

The righty returned to the mound late in 2019 but has struggled over the past few years. He made 13 appearances in the shortened 2020 season but with a 5.25 ERA. The Angels non-tendered him after that but he secured a major league deal from the Mariners for 2021. The change of scenery didn’t help much, with the righty posting a 4.94 ERA over 32 appearances that season.

After a couple of rough seasons, Middleton had to settle for a minor league deal with the Diamondbacks for 2022. He pitched well enough in the minors to get back into the big leagues, but his 18 appearances for Arizona resulted in a 5.29 ERA. He did reduce his walk rate to 4.3% after being much higher in the preceding campaigns, but his strikeout and ground ball rates were both subpar. He also allowed five home runs in that brief time, matching his total from the four previous seasons combined. He was cut from the roster in November and became a free agent again.

Middleton will now look to get back on track after a rough few years. Despite some poor results, he does average over 95 mph on his fastball, placing him in the 74th percentile of qualified pitchers, according to Statcast. If he can claw his way back onto the club’s roster, he won’t be able to be optioned to the minors without his consent since he has over five years of MLB service time.

A’s Claim Yonny Hernandez From Diamondbacks

By | at

The Athletics announced that they have claimed infielder Yonny Hernandez off waivers from the Diamondbacks. Additionally, the club has outrighted infielder Nate Mondou, left-hander Sam Selman and righties Austin Pruitt, Norge Ruiz, and Collin Wiles. The Diamondbacks also announced the claim of Hernandez, while relaying that infielder Jake Hager and right-hander Keynan Middleton cleared waivers and elected free agency.

This is one of the times on the baseball calendar when roster turnover is high, for a couple of reasons. First, there is no injured list between the World Series and Spring Training, meaning that players on the 60-day IL will soon be retaking their spots. Secondly, the deadline to add prospects to the 40-man roster in order to protect them from being selected in the Rule 5 draft is November 15. Those two factors both combine to squeeze certain players off rosters and onto waivers.

Hernandez, 25 in May, had spent all of his career in the Rangers organization until being traded to the D-Backs in April. He got into 12 MLB games this year, spending much more time in the minors. He hit .241/.349/.324 in 71 Triple-A games this year, wRC+ of 78. That’s not an especially impressive showing, but Hernandez fared much better in previous seasons and has always had good plate discipline. Despite the rough year, he still walked in 11.7% of his plate appearances and struck out in just 15.8% of them, with both of those numbers being much better than average. He’s never hit for much power though, having only hit five home runs in a minor league career that dates back to 2015. He still has options, meaning the A’s can keep him in the minors next year and try to see if they can draw something extra out of him.

Mondou, 28 in March, was just selected to the roster in October. He made his MLB debut by getting into one game where he made three hitless plate appearances, walking once and striking out once. In 108 Triple-A games, he hit .283/.374/.431 for a wRC+ of 105. Given his seven years of minor league experience, he will be eligible to elect free agency five days after the World Series.

Selman, 32 this month, has thrown 73 MLB innings over the past four seasons. He has a 4.81 ERA in that time with a 22.5% strikeout rate, 10.3% walk rate and 29.6% ground ball rate. He cut his walk rate to 6.7% in 2022 but also gave up four home runs in just 18 1/3 innings, leading to a 4.91 ERA. He’s eligible to elect free agency by virtue of having been previously outrighted in his career.

Pruitt, 33, signed a minor league deal with the A’s for 2022 and was twice selected to the roster with one DFA in between. He got into 55 1/3 innings on the season and registered a 4.23 ERA. His 17% strikeout rate was below average but he limited walks to a 4% rate and also got grounders on 45.5% of balls in play. He’s eligible to elect free agency both on account of his previous outrights and more than three years of service time.

Ruiz, 29 in March, was once a high-profile signing out of Cuba but saw his stock fade in recent years. A switch from starting to relieving in 2019 seemed to give him a boost, leading to him getting to make his MLB debut in 2022. He tossed 19 innings with a 7.11 ERA, though a .413 batting average on balls in play could indicate there’s some bad luck in there. He had a much nicer 3.73 ERA in 41 Triple-A innings. He should stick with the A’s as depth but without taking up a roster spot.

Wiles, 29 in May, got the call to the big leagues for the first time in September. He was able to log 9 2/3 MLB innings while putting up a 4.66 ERA in that small sample. He worked as a starter in the minors, logging 143 1/3 Triple-A innings with a 5.40 ERA. He limited walks to a 4.3% rate but was undone by 27 long balls in the hitter-friendly Pacific Coast League.

Hager, 30 in March, appeared in 28 big league games for Arizona this year, hitting .240/.345/.280 in that time for a wRC+ of 84. He had fairly similar results in 72 Triple-A games, adding a bit more pop but walking less. He’s eligible to elect free agency based on the fact that he’s been previously outrighted in his career.

Middleton, 29, has appeared in each of the past six seasons, spending time with the Angels and Mariners before suiting up with the Diamondbacks in 2022. He tossed 17 innings in the majors and another 17 in Triple-A this year, with better results in the minors. He had a 5.29 ERA in the bigs along with a 2.12 ERA for Reno. He is eligible to elect free agency both because of he has more than three years of MLB service time and a previous career outright.

IL Placements: Brubaker, Middleton

By | at

Catching up on some injured-list transactions around baseball…

  • The Pirates placed right-hander JT Brubaker on the 15-day injured list, retroactive to September 16.  Right-hander Luis Ortiz was called up to take Brubaker’s spot on the active roster.  Brubaker was officially listed as sidelined due to right arm inflammation, though lat soreness was given as the reason for his early exit from Thursday’s game, when he lasted just three innings.  Over 141 1/3 innings and 27 starts for the Bucs this season, Brubaker has a 4.58 ERA and some unimpressive Statcast numbers, though his SIERA is a more favorable 3.95.  His ability to eat innings could put him in the conversation for a spot in Pittsburgh’s rotation next season, even if he doesn’t make it back for one more start in 2022.
  • The Diamondbacks placed right-hander Keynan Middleton on the 15-day IL due to a sprained left big toe.  Righty Luis Frias was called up from Triple-A in the corresponding move.  The toe sprain will likely end what has been an injury-plagued season for Middleton, who missed a couple of months due to elbow inflammation and a right ankle sprain.  Between the injuries and time in the minor leagues, Middleton was limited to 17 innings in 18 appearances with the D’Backs, and he posted a 5.29 ERA over that rather small sample size.  Now in his sixth MLB season, Middleton has yet to regain the early promise of his first two seasons with the Angels, before Tommy John surgery sidelined him in 2018.  He inked a minors deal with the D’Backs last winter and probably seems likely to be back on the open market this offseason in search of another non-guaranteed deal.

Diamondbacks Select Wilmer Difo, Designate Noe Ramirez

By | at

The Diamondbacks announced they’ve selected infielder Wilmer Difo onto the big league roster. They’ve also reinstated relievers Keynan Middleton and Kyle Nelson from the 15-day injured list. To create space on the active and 40-man rosters, Arizona designated right-hander Noé Ramirez for assignment.

Difo gets his first MLB crack of the year, reaching the big leagues for what’ll be an eighth straight season. A switch-hitting middle infielder, Difo has decent contact skills but doesn’t offer much in the way of power production. He’s a .251/.313/.355 hitter in exactly 1300 MLB plate appearances split between the Nationals and Pirates, with the vast majority of that time coming in Washington. Difo has ample experience all throughout the infield, and he’s generally rated well in the eyes of public defensive metrics as a shortstop.

It’s been a similar story in Triple-A Reno this year. The 30-year-old has logged plenty of action at shortstop and third base, and he’s compiled a .269/.311/.398 line over 306 trips to the plate. Difo has struck out in just 13.4% of his plate appearances, but his lack of extra-base impact has been glaring in one of the more hitter-friendly environments in affiliated ball. He’ll nevertheless get a look on the strength of his glove, offering manager Torey Lovullo a defensive specialist off the bench for the stretch run. Difo will be arbitration-eligible this winter and could be kept around for next season, although he’s a likelier non-tender candidate given his journeyman status and below-average offensive showing in Triple-A.

Nelson and Middleton have each missed over a month dealing with injuries: back spasms for Nelson, an ankle strain for Middleton. The former has made 38 appearances during his first season in the desert, working to a sparkling 1.57 ERA in 34 1/3 innings but only striking out 20.5% of opponents. The latter has only pitched 12 times, pitching to a 1.64 ERA with a 25% strikeout rate in 11 frames.

With Nelson and Middleton returning to the bullpen, the D-Backs had to cut one of their incumbent pitchers. (Teams must devote one of the two extra roster spots in September to a position player). The veteran Ramirez finds himself as the odd man out after posting a lackluster 5.22 ERA through 50 innings. Ramirez has punched out 23.7% of batters faced on a solid 11.8% swinging strike percentage, but he’s also walked batters at an alarming 12.1% clip.

The 32-year-old Ramirez spent most of last season in Arizona as well. He signed a minor league deal after being released by the Angels and made the big league roster in June. Ramirez impressed enough down the stretch the D-Backs agreed to bring him back on a $1.25MM salary. They weren’t prepared to do so again this winter, and they’ll now place him on waivers in the next couple days.

If no other team wants to assume the remaining $240K on his contract, Ramirez is likely to head to the open market. He has more than five years of major league service time, giving him the right to refuse an outright assignment in favor of free agency while still collecting the remainder of his guaranteed salary.

Diamondbacks Place Ian Kennedy On 15-Day IL

By | at

The Diamondbacks placed right-hander Ian Kennedy on the 15-day injured list due to right calf inflammation.  The club also announced that Keynan Middleton was called up from Triple-A Reno to take Kennedy’s place on the active roster.

Kennedy had to make a quick departure from Sunday’s game due to the injury, and was scheduled to undergo an MRI today.  While the specifics of that MRI result aren’t known, things were obviously serious enough for the D’Backs to put Kennedy on the injured list.

A timetable isn’t yet known about when Kennedy could return, though even if he is able to get back on the mound after the 15-day minimum, he won’t have much time to audition for possible trade suitors.  The 35-44 Diamondbacks are looking like sellers at the August 2 trade deadline, and Kennedy (signed to a one-year, $4.75MM deal in March) is a logical candidate to be moved as a rental player.

Since becoming a full-time reliever prior to the 2019 season, Kennedy has sandwiched two solid years around an injury-plagued 2020 campaign.  This year in Arizona, the 37-year-old has a 3.58 ERA over 27 2/3 innings, but with plenty of unfavorable Statcast metrics.  The righty’s 10.4% walk rate is his highest since 2009, and his 20% strikeout rate is well below the league average.

Kennedy’s trade value could be a moot point if his injury continues to linger throughout July.  However, given his track record, there is a chance a team could look past both his health issues and his poor advanced metrics and swing a deal with the D’Backs, even if Arizona might end up still eating the bulk of Kennedy’s remaining salary.

Diamondbacks Place Mark Melancon On Injured List, Select Keynan Middleton

By | at

The D-Backs announced they’ve placed closer Mark Melancon on the injured list. His placement was without a designation, indicating it’s related to COVID-19. Keynan Middleton was selected to take his place on the roster. Additionally, Arizona recalled Caleb Smith from Triple-A Reno and optioned southpaw Tyler Holton.

Melancon is the second Arizona reliever lost to the COVID list in as many days. The Snakes also placed J.B. Wendelken on the IL yesterday. Placement on the list can indicate a positive test, viral symptoms or exposure to a person who has tested positive. It isn’t clear whether Melancon has tested positive.

Middleton signed a minor league deal over the offseason. The righty has appeared in each of the past five MLB seasons, spending his career with the Angels and Mariners. Middleton had some strong numbers early on with Los Angeles, but he’s struggled since undergoing Tommy John surgery in 2018. Last season, he tossed 31 innings of 4.94 ERA ball, only striking out 17.1% of batters faced while walking 13.6% of opponents.

Assigned to Reno to open the year, the 28-year-old has made seven appearances. He’s worked 7 1/3 frames of one-run ball, punching out nine while allowing five hits and three walks. That promising start will earn him another chance in the big leagues.

Diamondbacks Sign Braden Bishop, Keynan Middleton To Minors Deals

By | at

The Diamondbacks recently signed outfielder Braden Bishop and reliever Keynan Middleton to minor league contracts, according to Chris Hilburn-Trenkle of Baseball America. Both players had qualified for minor league free agency at the end of last season after clearing outright waivers during the year.

Bishop has spent the entirety of his big league tenure with the Mariners. A 3rd-round pick in the 2015 draft, the speedy center fielder reached the majors in 2019. He’s tallied 99 cumulative plate appearances over the past three seasons, hitting .133/.188/.156. Seattle designated Bishop for assignment in May, and he landed with the Giants on waivers. Within days of claiming him, San Francisco DFA’d the right-handed hitter themselves, and on that occasion he passed through unclaimed.

Despite putting up an impressive .326/.388/.549 line across 320 trips to the plate with the Giants’ top affiliate from that point forth, Bishop didn’t make it back to the majors. The 28-year-old will try to play his way back into the big leagues with their division rivals in Arizona. The D-Backs have a glut of young outfielders on the 40-man roster, but none of Daulton Varsho, Stuart Fairchild, Pavin Smith, Cooper Hummel or Jake McCarthy has yet gotten settled at the major league level.

Middleton has pitched in the majors in each of the past five seasons. He’d spent his entire career in the AL West, beginning as a third-round pick of the Angels in 2013. He pitched for four years in Anaheim, including a 3.43 ERA in 80 appearances over his first two seasons. Middleton underwent Tommy John surgery midway through the 2018 campaign, however, and he wasn’t as effective upon his return from that procedure.

Cut loose by the Angels last offseason, the right-hander latched on with the Mariners (where he and Bishop briefly overlapped). Middleton worked 31 innings across 32 appearances with Seattle but didn’t find a ton of success, posting a 4.94 ERA with worse than average strikeout and walk numbers (17.1% and 13.6%, respectively).

Recent struggles aside, it’s easy to see why the D-Backs would take a no-risk shot on Middleton in hopes he can rediscover some of his early form. The 28-year-old still averaged 95.6 MPH on his fastball last year. Perhaps of more interest, Middleton generated swinging strikes on a very strong 14.2% of his offerings — a surprisingly high number given his low strikeout rate. Arizona relievers had a 5.08 ERA and ranked dead last in strikeout/walk rate differential (9.7 percentage points), so Middleton should have a good chance at cracking the roster with a strong showing in Spring Training.

Players Recently Electing Free Agency

By | at

We’ve seen dozens of players elect minor league free agency over the past couple weeks, and that has continued to be the case in recent days. We’ll round up a few more players who are hitting the open market here, courtesy of the Triple-A transactions trackers.

Players can qualify for minor league free agency in a few ways. The most notable of these include: players with 3+ years of MLB service time who have been outrighted off their teams’ 40-man rosters this season, players who have been outrighted off a 40-man roster multiple times in their careers, and unsigned players not on a 40-man roster who have spent parts of at least seven seasons on a minor league roster or injured list.

Each of this group of players has hit the market within the past week and not yet been covered at MLBTR:

Mariners Place Jake Fraley, Anthony Misiewicz On 10-Day Injured List

By | at

The Mariners made a handful of roster moves today. They placed Jake Fraley on the 10-day injured list with right shoulder inflammation. Anthony Misiewicz was also placed on the injured list because of a left forearm strain.

Fraley has made headway this season in making himself a big league outfielder, slashing .213/.359/.388 in 220 plate appearances, making his season thus far worth 1.5 rWAR. Misiewicz, meanwhile, has made 54 appearances covering 46 1/3 innings. He has a 4.08 ERA/3.32 FIP, 24.1 percent strikeout rate, 5.6 percent walk rate, and 44.9 percent groundball rate.

To fill their roster spots, Wyatt Mills was recalled from Triple-A, and Jimmy Yacabonis had his contract selected. To make room on the 40-man roster, Shed Long was transferred to the 60-day injured list. Long went on the injured list on July 30, so he’s very likely done for the year. Keynan Middleton was also outrighted to Triple-A Tacoma.

Yacabonis will make his first appearance in the bigs since last year when he made two appearances with the Mariners. For his career, he owns a 5.71 ERA/6.05 FIP across 104 innings, mostly with the Orioles from 2017 to 2019. The 29-year-old right-hander has been sharp in Triple-A this season, tossing 31 1/3 innings with a 1.74 ERA. He will provide the Mariners with some length out of the bullpen should they need it.

Mariners Claim Sean Doolittle Off Waivers From Reds

By | at

The Mariners have claimed veteran reliever Sean Doolittle off waivers from the Reds, per a team announcement. Fellow reliever Keynan Middleton has been designated for assignment in a corresponding move. Doolittle had been designated for assignment earlier this week.

For the bulk of his career, Doolittle has been an elite reliever. After breaking into the big leagues in 2012, he posted an ERA of 3.23 or lower every year through 2018 (excluding a 2015 campaign in which he logged just 13 2/3 innings due to injury). That run of consistency earned him the closer’s role in Oakland, a job he held after being traded to the Nationals in 2017.

Doolittle has fallen on harder times over the past few seasons. While he posted strong strikeout and walk rates in 2019, an increase in home runs allowed pushed his ERA up to 4.05. The southpaw then missed most of last year’s shortened campaign due to knee and oblique issues. Upon reaching free agency, he signed a $1.5MM guarantee with the Reds over the winter.

While he has stayed healthy all year, Doolittle didn’t find enough success to stick in the Cincinnati bullpen over the entire season. His strikeout and walk rates (23.7% and 10.4%, respectively) have dipped to about league average for the first time in his career. And while Doolittle hasn’t been quite as home run prone this season as he was two years back, his 18.2% ground-ball rate is the lowest mark among the 207 relievers with 30+ innings pitched. That made for a tough fit in the hitter-friendly Great American Ball Park.

Doolittle’s fly-ball heavy ways are easier to manage in Seattle’s more spacious T-Mobile Park. And while Doolittle’s strikeout and walk rates suggest he’s no longer the elite late-innings option he was at his peak, the 34-year-old still looks to be at least an average middle reliever.

Acquiring Doolittle comes with very little risk, as the M’s will simply have to assume the remainder of that modest $1.5MM deal (approximately $295K). For a Seattle club a mere two and a half games back of the final Wild Card spot in the American League, it’s a worthwhile cost to bolster the bullpen depth for the season’s final five weeks. If the Mariners do make the playoffs, Doolittle will be eligible for the postseason roster because he was acquired before August 31.

To make room for Doolittle, the Mariners do run the risk of losing Middleton. A well-regarded relief prospect during his days in the Angels’ system, Middleton broke into the majors with a very promising rookie season in 2017. By early the following year, he had assumed the closing duties in Anaheim.

Unfortunately, Middleton blew out his elbow in May 2018 and required Tommy John surgery. His stuff didn’t look the same upon his return and the Angels non-tendered last winter after he spent most of the 2020 campaign at the alternate training site. Seattle jumped in to add the righty on a one-year, $800K guarantee in free agency.

Middleton has logged significant action for Seattle this season but hasn’t recaptured his peak form. Across 31 frames, he’s managed just a 4.94 ERA with a career-low 17.1% strikeout rate and a lofty 13.6% walk percentage. Middleton has actually induced plenty of swinging strikes (14.2%) but they’ve yet to translate into consistent results.

Seattle will now place Middleton on waivers over the coming days. Another team could take a speculative flier in the hope that Middleton’s swing-and-miss stuff and still strong velocity could lead to stronger production moving forward. Any claiming team could keep him under club control through 2023 via arbitration if he figures things out down the stretch.
