Prelander Berroa

White Sox Promote Ky Bush For MLB Debut

By | at

August 5: The White Sox made it official today, selected Bush’s contract. They also reinstated right-hander Dominic Leone from the 60-day injured list. Right-hander Prelander Berroa and left-hander Sammy Peralta were optioned in corresponding moves. The 40-man roster is now full.

August 4: The White Sox will select the contract of left-hander Ky Bush prior to their next game on Tuesday, the Chicago Sun-Times’ Daryl Van Schouwen reports (via X).  Bush will get the start against the A’s in his Major League debut.  No 40-man roster move is required, as the Sox have space available after all their moves at the trade deadline.

A second-round pick in the 2021 draft, Bush was part of a unique Angels draft class that saw the team use all 20 of its selections on pitchers.  He pitched at the Double-A level in 2022-23 and at the start of the 2024 season, with both a lat strain and a trade to Chicago interrupting his progress last season.  Bush and Edgar Quero were the prospects sent from the Angels to the White Sox in the July 2023 deal that brought Lucas Giolito and Reynaldo Lopez to Los Angeles.

Bush settled in with his new organization this season, delivering a 2.12 ERA over 80 2/3 Double-A innings.  This earned him his first taste of Triple-A action, though he has a 6.16 ERA in 19 innings and four appearances in Charlotte.  For the season as a whole, Bush’s ERA is 2.89 over 99 2/3 frames, with a 10.45% walk rate, and 23.4% strikeout rate.

Baseball America ranked Bush sixth on its midseason ranking of the White Sox prospect pool, noting that the 24-year-old has “”No. 4 starter potential” and an arsenal of “solid pure stuff.”  To that latter point, BA’s scouting reports puts a 50 grade on all four of Bush’s pitches, though his slider is considered his best offering.

It isn’t the standout resume that would immediately land a pitcher a ticket to the big leagues, but the 24-year-old Bush will get a chance to show what he can do against MLB competition.  The rebuilding White Sox will be giving plenty of playing time to young players down the stretch, so a good showing could certainly earn Bush more looks in the rotation.  If the pressure of making his debut in the Show wasn’t enough, Bush will also be trying to help the White Sox end a 20-game losing streak that is nearing record levels.

White Sox Select Brad Keller, Designate Deivi Garcia For Assignment

By | at

The White Sox announced a series of roster moves this morning, highlighted by the club selecting the contract of veteran right-hander Brad Keller. Right-hander Deivi Garcia was designated for assignment to make room for Keller on the 40-man and active rosters. Additionally, Chicago announced that right-hander Jonathan Cannon had been optioned to Triple-A Charlotte. Right-hander Prelander Berroa was recalled to take Cannon’s place on the active roster.

The news leaves Keller poised to make his White Sox debut in the coming days as he likely steps into the rotation in Cannon’s stead. The 28-year-old signed a minor league deal with Chicago in early March after lingering on the free agent market throughout the offseason following a difficult 2023 campaign. Keller was limited to just 45 1/3 innings of 4.57 ERA baseball last year due to shoulder surgery and a thoracic outlet syndrome diagnosis, which MLB.com’s Mark Feinsand noted last month necessitated its own surgery back in October.

Surgery to correct TOS has rarely seen players return to the majors and enjoy success, with Stephen Strasburg and Chris Archer among the arms who have seen their careers impacted by the procedure in recent years. One example of a player who has returned effectively is Arizona right-hander Merrill Kelly, who stands as a prime example of the fact that not all types of TOS have the same long-term outlook. It’s not clear which type of TOS Keller went under the knife due to, though his decent 4.50 ERA in 16 innings of work at the Triple-A level across three starts this season gives reason for optimism that he could return to form as a viable back-of-the-rotation option in the majors.

Making room for Keller on the 40-man roster is Garcia, who will celebrate his 25th birthday next month. The right-hander was once a top prospect in the Yankees’ farm system and made his big league debut at just 21 years old during the shortened 2020 season, which saw him post a 4.98 ERA and 4.15 FIP across six starts in New York. Unfortunately, Garcia then struggled badly in the minor leagues over the next two seasons, with ERAs north of 6.80 in both campaigns. Garcia’s time with the Yankees came to a close in 2023, when he was designated for assignment after struggling through two relief appearances in the majors.

The White Sox took a chance on Garcia and claimed him off waivers from New York before installing him in the club’s bullpen. While he posted a strong 2.04 ERA in six appearances with the club down the stretch last year, Garcia walked more batters than he struck out and posted an ugly 6.04 FIP during that same timeframe. While Chicago retained Garcia on its roster through the offseason, the results began to match the peripherals in 2024 as the right-hander surrendered 16 runs (11 earned) in just 14 innings while walking 16.2% of batters faced.

Those major struggles were evidently enough for the White Sox to pull the plug on Garcia, who they’ll now have one week to either work out a trade for or attempt to pass through waivers. If they’re successful in the latter, they’ll have the opportunity to outright the youngster to the minor leagues where he can serve as non-roster depth going forward.

Also departing the club’s active roster is Cannon, a 23-year-old rookie who has made three starts in the majors for the White Sox so far this year. That first taste of big league action hasn’t gone particularly well for the youngster, as he’s posted a brutal 7.24 ERA in 13 2/3 innings of work despite a solid 4.04 FIP. Cannon figures to return to the Triple-A rotation and wait for his next opportunity in the majors.

In the meantime, his roster spot will go to Berroa, who figures to replace Garcia in the club’s bullpen. The 24-year-old right-hander was acquired from the Mariners in the deal that sent Gregory Santos to Seattle back in February and has just 1 2/3 big league innings under his belt to this point in his career. He’s struggled mightily to this point at the Triple-A level this season, with an 8.74 ERA across 11 appearances. Nonetheless, he’ll look to contribute to the White Sox bullpen during the middle innings alongside the likes of Jordan Leasure and Dominic Leone.

Mariners Acquire Gregory Santos

By | at

The Mariners have acquired right-hander Gregory Santos from the White Sox in exchange for right-hander Prelander Berroa, outfielder Zach DeLoach, and their 2024 Competitive Balance Round B draft pick (#69 overall), according to Jeff Passan of ESPN. Both clubs have since announced the deals. To make room for the club’s additions on the 40-man roster, the White Sox announced that they’ve designated right-hander Lane Ramsey for assignment.

Santos, 24, entered the 2023 campaign with just 5 2/3 innings in the majors under his belt for his career but fashioned a strong rookie performance out of the White Sox bullpen last year. The right-hander posted a strong 3.39 ERA in 66 1/3 innings of work across 60 appearances for Chicago last season, and those already solid numbers are backed up by even stronger peripherals. Santos paired a solid 22.8% strikeout rate with a microscopic 5.9% walk rate last season all while generating grounders at an excellent 52.5% clip. Those quality peripheral numbers left Santos with a 2.65 FIP last year, a figure bested by only Felix Bautista, Tanner Scott, Matt Brash, and David Bednar among relief arms with at least 60 innings of work last year.

Given the presence of both Brash and flamethrowing closer Andres Munoz at the back of Seattle’s bullpen, it seems unlikely that Santos will find himself in line for many save opportunities with the Mariners after picking up five saves in eight opportunities with the White Sox last season. That being said, Santos appears likely to step into the void created by right-hander Justin Topa’s departure from the club’s late-inning mix. Topa, who posted a 2.61 ERA and 3.15 FIP for the Mariners last year, was shipped to Minnesota last week alongside Anthony DeSclafani and two prospects in exchange for infielder Jorge Polanco. While reporting earlier this winter indicated that Santos may not be ready for Spring Training after ending the season on the injured list with elbow inflammation, MLB.com’s Daniel Kramer relays that the Mariners expect Santos to make six to eight appearances this spring in preparation for Opening Day.

In exchange for parting ways with a quality relief arm with five seasons of team control remaining, the White Sox are receiving a pair of rookie-eligible youngsters as well as what should become a third noteworthy piece in the form of the #69 selection in this year’s draft. That will be Chicago’s third pick in next year’s draft as things stand, as they will also draft the #5 and #43 selections this summer.

Berroa, 23, was acquired by the Mariners back in May of 2022 in a deal that sent Donovan Walton to San Francisco. The right-hander was listed as Seattle’s #15 prospect by MLB.com last season on the heels of a 2022 campaign that saw him post a 2.86 ERA in 26 starts split between the High-A and Double-A levels of the minors. The Mariners converted Berroa to the bullpen in 2023 and he found considerable success in the role as he punched out 36.6% of batters faced while compiling a 2.89 ERA in 65 1/3 innings of work in a return to Double-A last year. Impressive as those strikeout numbers are, Berroa’s penchant for issuing free passes stands out as a possible red flag. The righty walked 14.1% of batters faced last season and has walked at least 11.8% of opponents every year since he made the jump to full-season ball back in 2019.

Though the youngster has yet to appear at the Triple-A level to this point in his career, he got his first taste of big league action last year, with 1 2/3 scoreless innings of work across his first two appearances in the majors. There should be plenty of opportunities this season for the righty to step into a significant role in Chicago’s bullpen, where they figure to rely on the likes of John Brebbia, Tim Hill, and Garrett Crochet as late-inning options.

As for DeLoach, the 25-year-old was Seattle’s second-round pick in the 2020 draft. Early in his professional career, DeLoach struggled to create much power with his swing, clubbing just 14 home runs in each of his first two pro campaigns. The right fielder managed to improve his power output this past season, however, as he slashed .286/.387/.481 in 623 trips to the plate at the Triple-A level. While that translates to a wRC+ of just 111 in the inflated offensive environment of the Pacific Coast League, where the Mariners’ Triple-A affiliate plays its games, DeLoach’s 23 homers last season still show the power potential necessary to make him a potential big league contributor as soon as this season.

While star slugger Luis Robert Jr. is locked into the everyday center field job and veteran outfielder Andrew Benintendi figures to get the lion’s share of starts in left for the White Sox this year, the club’s right field situation is far less certain. Oscar Colas was the club’s main contributor at the position last year, though he posted a brutal .216/.257/.314 slash line in 75 games with the big league club last year. As such, there’s plenty of room for either DeLoach or fellow recent addition Dominic Fletcher to seize an everyday role with the club during Spring Training later this month. That trio also figure to battle with non-roster invitees Brett Phillips and Kevin Pillar for the club’s fourth outfield role headed into Opening Day.

Making room on the 40-man roster for the additions of DeLoach and Berroa is Ramsey, a 27-year-old who made his big league debut last season. Originally acquired by the White Sox in the 23rd round of the 2018 draft, Ramsey struggled to a 5.85 ERA in 20 innings of work with the big league club last year as he struck out just 19.6% of batters faced while walking 9.8%. The club will have seven days to either trade Ramsey or attempt to pass him through waivers. If they are successful in doing so, they’ll have the opportunity to outright him to the minor leagues where he’ll remain with the club as non-roster depth headed into the 2024 campaign.

Mariners Promote Prelander Berroa, Devin Sweet

By | at

The Mariners announced a few roster moves prior to tonight’s game, selecting the contract of right-hander Devin Sweet and recalling fellow righty Prelander Berroa, with both players set to make their respective major league debuts as soon as they get into a game. In corresponding moves, right-handers Ty Adcock and Isaiah Campbell were optioned to Double-A Arkansas. The club already had a 40-man vacancy and won’t need to make a corresponding move in that regard.

Berroa, 23, came over the Mariners last year in a trade that sent Donovan Walton to the Giants. Berroa finished last year with a combined 2.86 earned run average across those two systems and different minor league levels, tossing 100 2/3 innings. The M’s liked him enough to give him a 40-man roster spot in November in order to protect him from being selected in the Rule 5 draft.

He started this year in the Double-A rotation but had a 5.16 ERA through his first five starts. He was moved to the bullpen at that point in a move that seems to have worked out quite well. He’s thrown 23 1/3 innings over 19 appearances since taking on a relief role, posting a 0.77 ERA in that time. His 13.5% walk rate is certainly on the high side but he’s limiting damage by striking out 39.3% of batters faced. He won’t be able to sustain a .238 batting average on balls in play or 90.9% strand rate but the results are nonetheless encouraging enough to earn him a big league look. He’s currently considered the club’s #10 prospect at Baseball America and #11 at FanGraphs.

Sweet, 26, cracks a 40-man roster for the first time in his career. An undrafted free agent who signed with the Mariners in 2018, he’s been climbing the minor league ladder since then. He’s spent all of this year in Double-A, posting a 1.54 ERA in 35 innings over 27 appearances. He’s struck out 34.6% of opponents while walking just 5.9%. He’s ranked the club’s #26 prospect by BA and #29 at FanGraphs.

The Mariners suffered a rough 10-3 loss at the hands of the Twins last night, with Bryan Woo allowing six earned runs and getting bounced in the fourth inning. Each of Adcock, Campbell and Tayler Saucedo tossed 29 pitches or more, while many of the high-leverage hurlers appeared in close games on both Monday and Sunday. With a fairly taxed relief corps, these moves give the club an injection of fresh arms.

Mariners Select Four Players

By | at

The Mariners announced Tuesday that they’ve selected the contract of righties Prelander Berroa and Isaiah Campbell and outfielders Cade Marlowe and Jonatan Clase. All four are now on the 40-man roster and protected from being selected in next month’s Rule 5 Draft. The quartet of additions fills Seattle’s 40-man roster for the time being.

Each of Berroa (13), Clase (15) and Marlowe (21) rank within the organization’s top 30 prospects, per Baseball America. Mariners president of baseball operations had already confirmed last week that Berroa would be selected to the 40-man roster, though the other additions had not been made public.

Berroa, 22, was acquired from the Giants in a deal that sent infielder Donovan Walton to San Francisco. The Dominican-born righty split the year between the High-A affiliates of the Giants and Mariners before topping out with Seattle’s Double-A club later in the year. In a combined 100 2/3 innings, Berroa posted a 2.86 ERA with a gaudy 36.5% strikeout rate but also a problematic 15.3% walk rate.

Clase, just 20, draws 80-grade reviews for his speed and is considered a potential above-average or better defender in center field. He spent the year in Class-A, hitting .267/.373/.463 with a hearty 13% walk rate but also a more suspect 26.7% strikeout rate. While earlier scouting reports on him suggested he lacked power, Clase smacked 13 home runs in 499 plate appearances and posted a .196 ISO (slugging minus batting average) this season, showing more pop than some might have expected.

Marlow posted an impressive .287/.377/.487 slash with 23 home runs and a whopping 42 steals in 578 plate appearances between Double-A and Triple-A this season. It was an impressive enough showing that he was on the taxi squad and under consideration to make his Major League debut during the playoffs for the Mariners in 2022. The Mariners are expected to add some veteran outfielders this offseason, but Marlowe will be among the options if the team needs to tap into its depth in the event of an injury early in 2023.

Campbell, 25, was the Mariners’ second-round pick in 2019. The 6’4″, 230-pound righty tallied 21 saves and posted a pristine 1.57 ERA with a 33% strikeout rate against a 6.7% walk rate in 46 innings between High-A and Double-A this year.

It’s possible, though not a given, that the Mariners will have further moves in the hours ahead. Seattle is reportedly active on the trade market as teams look to set their rosters in advance of the deadline to protect players from the Rule 5 Draft. Seattle is reportedly open to dealing Jesse Winker on the heels of a disappointing season, and they’ve been receiving interest in fifth-starter candidates Chris Flexen and Marco Gonzales since the offseason began.

Mariners To Select Prelander Berroa

By | at

The Mariners are planning to select right-hander Prelander Berroa onto their 40-man roster, president of baseball operations Jerry Dipoto tells reporters (including Ryan Divish of the Seattle Times). The 22-year-old would otherwise be eligible for the Rule 5 draft this winter, and Seattle will keep him away from other clubs by adding him to the 40-man.

Seattle acquired Berroa in May, adding him from the Giants in a deal that sent utilityman Donovan Walton to San Francisco. It was the second trade of Berroa’s young career, as he’d previously gone from the Twins to the Giants in a 2019 deadline deal. A native of the Dominican Republic, Berroa draws praise from evaluators for his fastball-slider combination but has some questions about his control.

That was mostly borne out in his 2022 numbers. Berroa split his time between High-A and Double-A, starting all 26 of his appearances. He posted a cumulative 2.86 ERA through 100 2/3 innings, striking out an incredible 36.5% of batters faced. He also walked an elevated 12.6% of opponents, highlighting that his strike-throwing remains a work in progress. Nevertheless, the M’s feel there’s a chance another club would’ve plugged Berroa directly onto the MLB roster next year given the quality of his stuff.

Giants Acquire Donovan Walton, Designate Mike Ford

By | at

The Giants have acquired infielder Donovan Walton from the Mariners in exchange for pitching prospect Prelander Berroa, according to announcements from both teams. San Francisco has designated first baseman Mike Ford for assignment to clear space on the 40-man roster.

Walton, 28 later this month, has appeared in the majors in each of the past four seasons. He’s tallied just 102 cumulative plate appearances across 37 games, though, and his only MLB outing this year saw him enter as a pinch-runner. A left-handed hitter, Walton has posted a modest .196/.260/.315 showing in the majors.

The Oklahoma State product has a more robust body of work in the minors, where he’s a .287/.375/.427 hitter in parts of six seasons. That includes a .302/.391/.518 line in just shy of 400 trips to the plate at Triple-A, and Walton’s hitting .294/.368/.510 through 12 contests there this season. Perhaps of greatest import to the Giants, he’s a versatile defender who has a ton of professional experience in the middle infield. He figures to bounce around the diamond in a utility capacity for a Giants team that has dealt with injuries to both Evan Longoria and Tommy La Stella (although Longoria is making his season debut today). Walton is in his final minor league option year, meaning the Giants can shuttle him between San Francisco and Triple-A Sacramento for the remainder of the season if he sticks on the 40-man roster.

Walton, somewhat ironically, becomes the third infielder the Giants have acquired from Seattle in as many weeks. San Francisco also picked up Kevin Padlo on April 26 and acquired Ford on April 30. Both those deals were for cash considerations, but the M’s recoup a minor league arm in exchange for Walton.

Berroa, a 22-year-old righty, originally signed with the Twins as an amateur out of the Dominican Republic. San Francisco acquired him at the 2019 trade deadline, and he’s spent the past few seasons in the lower levels of the farm system. Baseball America named Berroa the #29 prospect in the Giants’ system over the offseason, writing that he owns a mid-upper 90s fastball and a solid slider. The outlet suggested Berroa’s control is a work of progress but that he has a chance to develop into a back-of-the-rotation starter.

Over four appearances with High-A Eugene this season, Berroa has worked 13 1/3 innings of one-run ball. He has 16 punchouts and six walks, a continuation of the high-strikeout, high-walk ways he’s shown throughout his young career. Berroa will be eligible for the Rule 5 draft this winter if he’s not added to the Mariners’ 40-man roster.

Ford, meanwhile, suited up in just one game in black and orange. He collected a single in four plate appearances and has a .271/.417/.417 line over 60 Triple-A plate appearances this season. It’s the second time this year that Ford has been designated for assignment, as a DFA preceded the aforementioned trade from Seattle to San Francisco. The Giants will have a week to trade the 29-year-old or try to run him through outright waivers.
