Sammy Peralta

Nicky Lopez, Sammy Peralta Elect Free Agency

By | at

The White Sox announced that both infielder Nicky Lopez and left-hander Sammy Peralta cleared waivers and elected free agency in lieu of accepting outright assignments. The club’s 40-man roster count drops to 36.

There wasn’t any previous indication that either player had been removed from the roster, but it’s a common time of year for a bit of shuffling. The Rule 5 protection deadline is coming up on November 19, meaning that all clubs are likely going to be needing a few spots to shield young players from that draft. As that deadline date approaches, roster spots around the league will be at a premium, increasing the chances of a player being nudged off and then passing through waivers unclaimed.

Lopez, 30 in March, has a decent track record now as a glove-first utility player. He was acquired by the White Sox as part of the November 2023 trade that sent Aaron Bummer to Atlanta, then went on to appear in 124 games for Chicago this year. He hit just one home run in 445 plate appearances, leading to a pyramid-shaped slash line of .241/.312/.294. That production translated to a 77 wRC+, indicating he was 23% worse than league average at the plate.

That season brought his career batting line to .248/.312/.314, which equates to a 73 wRC+. Lopez has been able to bounce around the field, playing all four infield spots and even a small amount in the outfield, stealing some bases here and there as well. But the bat is clearly subpar, with seven career homers in 2,346 trips to the plate.

The Sox could have retained him for one more season via arbitration, with MLBTR contributor Matt Swartz projecting him for a salary of $5.1MM, but it seems the Sox weren’t planning to do that. Lopez has more than enough service time to reject an outright assignment, so he’ll head to the open market. He’ll likely garner interest from clubs interested in a depth infielder, either on a minor league deal or a major league pact with a modest guarantee.

Peralta, 27 in May, was first selected to Chicago’s roster in May of 2023, but he’s been on and off since then. He was designated for assignment in March of this year, went to the Mariners via waivers, but then came back to the Sox via another waiver claim in May. Shortly after coming back to the Sox, he was put back on waivers and cleared, getting outrighted to Triple-A. He was selected back to the 40-man in June but has now been outrighted for a second time.

Around those transactions, he has thrown 35 big league innings with a 4.37 earned run average, 17.9% strikeout rate and 11.1% walk rate. His Triple-A track record consists of 125 2/3 innings over the past three years. He has a 4.80 ERA at that level, along with a 24.1% strikeout rate and 8.8% walk rate.

Since this is his second career outright, he has the right to elect free agency and has done so. He will market himself to other clubs around the league and will likely be looking at minor league offers.

White Sox Claim Jacob Amaya, Designate Nick Senzel For Assignment

By | at

The White Sox announced today that they have claimed infielder Jacob Amaya off waivers from the Astros. The latter club had designated him for assignment on the weekend. Infielder Nick Senzel was designated for assignment by the White Sox in a corresponding 40-man roster move for the claim of Amaya. Infielder Bryan Ramos has been recalled to take Senzel’s active roster spot. The Sox also recalled left-hander Sammy Peralta and optioned lefty Ky Bush.

Amaya, 25, has just five major league games and ten plate appearances but is now joining the fourth organization of his career. An 11th-round pick of the Dodgers, he was flipped to the Marlins in the January 2023 trade that sent infielder Miguel Rojas to Los Angeles. He spent just over a year in the Marlins’ system but was designated for assignment in April of 2024 before being flipped to the Astros for right-hander Valente Bellozo and cash considerations.

Prospect evaluators have long praised Amaya for his defense, but his bat has been more questionable, which is borne out by the numbers. In 450 minor league games from 2021 to the present, he has slashed .240/.335/.384 for a wRC+ of 86. His 12.3% walk rate in that time is strong but he hasn’t made a ton of impact when putting the bat on the ball.

Amaya can still be optioned for the rest of this year but will be out of options next year. He has mostly played shortstop but has also seen some time at second and third base. The rebuilding Sox don’t have a ton set in stone in their future infield. Nicky Lopez has appeared in 105 games for them this year but is hitting a tepid .240/.309/.293 for a wRC+ of 74. He could be retained via arbitration for next year but would be a due a raise on his $4.3MM salary and could be non-tendered. Paul DeJong was traded to the Royals. Yoán Moncada is in the final guaranteed season of his contract and club won’t have much interest in picking up his $25MM club option for 2025.

Perhaps that will get Amaya a chance to earn some playing time for the rebuilding club. Even if his bat doesn’t come around, having a glove-first infielder is a sensible move for a rebuilding team that will undoubtedly be giving plenty of chances to unproven pitchers in the future.

That same uncertainty is what opened a spot for Senzel. The White Sox signed him in the middle of July after he was released by the Nationals. He got 32 plate appearances with the Sox but hit just .100/.129/.133 in those. Those struggles have nudged him off the roster and the Sox will have to put him on waivers now that the trade deadline has passed.

The Nats signed him to a one-year, $2MM deal in the offseason after he was non-tendered by the Reds. He was designated for assignment by the Nats in July, when a trade was still possible, but he ended up released. Presumably, the interest hasn’t been raised during Senzel’s tenure with the White Sox, so he’s likely to end up a free agent again.

Though he was once a second overall pick and ten ten prospect in the sport, his bat hasn’t played at the major league level. He has over 1600 plate appearances to this point but has hit .232/.299/.363 in those for a wRC+ of 76.

The Nats are still on the hook for the majority of that $2MM salary. If another club is intrigued by Senzel’s past prospect pedigree, they could sign him and pay him only the prorated portion of the $740K major league minimum salary. That amount would be subtracted from what Washington pays.

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 Promote Drew Thorpe For MLB Debut

By | at

June 11: The White Sox have officially announced Thorpe’s selection today. Left-hander Sammy Peralta was optioned to open a spot on the active roster. To open a spot on the 40-man, right-hander Dominic Leone was transferred to the 60-day injured list. Leone was put on the 15-day IL about three weeks ago due to inflammation in his throwing elbow and it now appears the Sox aren’t expecting him to return in the near future.

June 9: The White Sox are planning to promote top pitching prospect Drew Thorpe to the majors on Tuesday, manager Pedro Grifol told reporters (including James Fegan of SoxMachine). The right-hander will make his MLB debut against the Mariners in Seattle.

Thorpe, 23, was the headliner of a four player package the White Sox received from the Padres in the deal that sent ace righty Dylan Cease to San Diego back in March. It was the second time Thorpe had been traded that offseason, as the Padres acquired Thorpe from the Yankees as part of the Juan Soto package back in December. As one might expect from a prospect that was part of the return for two superstars in separate blockbusters during the same offseason, Thorpe is a consensus top-100 prospect in the sport. The righty currently ranks #41 at Baseball America and #54 at MLB Pipeline.

Prospect evaluation services universally praise Thorpe’s excellent command, ability to eat innings, and the devastating changeup that he complements with a 92-94 mph fastball that’s generally regarded as average and a average-or-better slider that sits in the mid-80s. Aside from his three main pitches, BA also notes that Thorpe mixes in a high-80s cutter and a low-80s curveball. That arsenal allowed the 2022 second-rounder to tear through the lower minors during his first taste of professional ball with the Yankees last year. Thorpe dominated to the tune of a 2.81 ERA with a 32.4% strikeout rate in 18 starts at High-A last year before earning a late season promotion to Double-A.

Thorpe’s star really began to rise with that promotion. The then-22-year-old impressed with a sparkling 1.48 ERA across five starts. The righty racked up a whopping 44 strikeouts in just 30 1/3 innings of work while walking just five. Punching out 40% of batters faced while walking just 4.5% in your first taste of Double-A action is a surefire way to get plenty of attention, and so it’s hardly a surprise that both the Padres and White Sox front offices coveted Thorpe enough to make him a key piece of the trade returns for their star players.

Upon joining the White Sox organization, the right-hander returned to Double-A for the start of the 2024 campaign and has continued to dominate hitters at the level, with similar surface-level numbers in 11 starts this season to his five-start taste of Double-A last year. Thorpe has pitched to a 1.35 ERA in 60 innings of work this year, though his strikeout rate has dipped to a more pedestrian 25% this year while his walk rate has crept up to 7.6%. Even with those diminished peripherals, however, Thorpe has more than proved himself capable at the Double-A level and figured to be in line for a promotion in the near future.

What’s surprising, then, isn’t so much the promotion but that he will skip Triple-A entirely and jump directly into big league action. The White Sox optioned right-hander Nick Nastrini to the minors earlier today, leaving them with just a vacancy in a starting rotation that lost Mike Clevinger to the injured list and now features only Garrett Crochet, Erick Fedde, Chris Flexen, and Jonathan Cannon. Rather than call up a veteran at the Triple-A level such as Chad Kuhl or Touki Toussaint to fill out the rotation, the White Sox will instead turn to Thorpe in a bold move to get the righty a taste of big league action.

It’s a decision that could come with financial implications for Thorpe, as he’ll be in a good position to earn a fourth arbitration year as a Super Two player if he remains with the big league club going forward without returning to the minor leagues. Thorpe could theoretically earn himself a full season of service time by finishing in the top 2 in AL Rookie of the Year voting this season, although that would be quite the feat given the massive head starts afforded to players like Luis Gil of the Yankees and Mason Miller of the A’s who have been dominating in the majors all season.

White Sox Designate Shane Drohan For Assignment

By | at

The White Sox announced a series of roster moves this morning, including that they’ve activated left-hander Shane Drohan from the 60-day injured list and designated him for assignment. In a separate move, the club selected the contract of left-hander Sammy Peralta. The club optioned right-hander Nick Nastrini to make room on the active roster. Chicago’s 40-man roster stands at 39.

Drohan, 25, joined the White Sox organization over the offseason when he was selected from the Red Sox in the Rule 5 draft. Chicago will have one week to either trade or waive Drohan, and if he clears waivers they must offer him back to Boston for $50K. If he lands with a new organization by trade or on waivers, Drohan’s Rule 5 obligations will carry over to that new club. Drohan underwent shoulder surgery back in February but began a rehab assignment on May 10. The 30-day window for Drohan’s rehab assignment ended today, meaning that he had to be activated from the IL and either placed on Chicago’s active roster in compliance with Rule 5 restrictions or designated for assignment.

The White Sox evidently chose to part ways with Drohan, and given his struggles during his rehab assignment it’s not hard to see why. In 9 1/3 innings of work over ten appearances spread across three levels of the minors, Drohan struggled to an 8.68 ERA with a 17.4% walk rate despite an excellent 32.6% strikeout rate. Those results worsened when he departed complex ball, as he yielded a 9.53 ERA with identical 20.7% strikeout and walk rates in seven appearances split between High-A and Triple-A. Even for a 17-48 club like Chicago, it’s difficult to justify dedicating an active roster spot to a player facing struggles that deep against minor league hitters.

Prior to the aforementioned shoulder surgery, Drohan had the look of an interesting pitching prospect in the Red Sox organization. The lefty dominated Double-A pitching to the tune of a 1.32 ERA with a 28.1% strikeout rate across six starts last year before being promoted to the Triple-A level. Drohan hit a wall during his time at Triple-A, however, as he walked 14.9% of batters faced across his 21 appearances (19 starts) while yielding a 6.47 ERA in 89 innings of work.

Those struggles were seemingly enough to convince Boston to leave Drohan off their 40-man roster this winter, although Chicago evidently believed that a move to short relief could help with Drohan’s control problems enough to make him a viable big leaguer. Should he wind up returning to Boston, it’s possible the Red Sox will keep Drohan in his new short relief role or perhaps look to stretch him back out as a potential depth option for the big league club in the event he manages to sort out his control issues.

As for Peralta, the lefty’s contract was first selected to the club’s roster back in May of 2023. He performed decently in a middle relief role for the club last year, with a 4.05 ERA and 4.41 FIP in 20 innings of work. Peralta’s lackluster minor league numbers and worrisome big league peripherals were enough to make him expendable for the White Sox as they sorted through their Opening Day roster crunch, and he was designated for assignment to make room for right-hander Jordan Leasure on the 40-man roster. That led to him being claimed off waivers by the Mariners, who then designated Peralta themselves to make room for righty Eduardo Salazar.

The White Sox then claimed him off waivers from Seattle to return him to the organization, only to designate him for a third time in two months in order to make room for righty Jake Woodford on 40-man roster. Peralta then finally cleared waivers and was outrighted to the minors in late May, but he spent less than two weeks there before being selected back to the roster today. Peralta’s rollercoaster first two months of the season have led him to a familiar role: that of a fill-in relief option who can pitch from the left side. The lefty struggled badly during his time in the Mariners organization but has 3 2/3 scoreless innings of work at the Triple-A level for the White Sox this year. He’ll hope to take that success into the majors with him as he joins the club’s bullpen alongside fellow lefties Tanner Banks, Jared Shuster, and Tim Hill.

As for Nastrini, the right-hander was a key component of the return for right-handers Lance Lynn and Joe Kelly after Chicago traded them to the Dodgers last summer. Nastrini has made six starts at the big league level so far this season and has generally struggled badly, with a 8.39 ERA and 7.92 FIP in just 24 2/3 innings of work. While he held the Red Sox to just one run over 4 1/3 innings last night, he walked five of the 19 batters he faced. That performance at the big league level has clearly indicated to the Sox that the 24-year-old needs more time in the minors before he can contribute on the south side on a more permanent basis.

White Sox Outright Sammy Peralta

By | at

The White Sox announced Thursday that left-hander Sammy Peralta, who was designated for assignment Tuesday, went unclaimed on waivers and has been assigned outright to Triple-A Charlotte.

It’s been a rollercoaster season for Peralta, whom the White Sox originally designated for assignment back on March 28 when setting their Opening Day roster. The Mariners claimed him off waivers and sent him to Triple-A Tacoma, where he was tagged for 13 runs in 12 2/3 innings of work. Seattle designated him for assignment over the weekend, at which point the White Sox claimed him back … only to again DFA him just two days later. This time, Peralta passed through waivers and will now remain in the Sox organization as a depth option in Charlotte.

Peralta, 26, made his big league debut with the Sox last season. In 20 innings he posted a 4.05 ERA with a 20% strikeout rate, 12.2% walk rate and 39.3% ground-ball rate. Peralta posted strong run-prevention numbers and big strikeout rates up through the Double-A level as he climbed through Chicago’s system following his 18th-round selection in the 2019 draft, but he’s been hit hard in 87 Triple-A frames (5.65 ERA) and had uncharacteristic struggles with his command dating back to last year’s initial MLB call-up.

White Sox Place Mike Clevinger On IL Due To Elbow Inflammation

By | at

White Sox announced that right-hander Mike Clevinger has been placed on the 15-day injured list due to right elbow inflammation, retroactive to May 25. Fellow righty Jake Woodford has been selected to the roster and will start tonight’s game in Clevinger’s place. Left-hander Sammy Peralta has been designated for assignment to open a 40-man spot for Woodford. Daryl Van Schouwen of the Chicago Sun-Times was among those to relay the Clevinger and Woodford on X prior to the official announcement.

Since Clevinger is being scratched just hours before his schedule start, it seems fair to conclude that it’s something that popped up recently. He tossed 4 2/3 innings in his most recent start, finishing with 98 pitches thrown that day. He says he has received a cortisone shot and will be shut down for 48 hours, per Van Schouwen on X. The righty expects to return after the 15-day minimum is up.

Clevinger underwent Tommy John surgery in 2020 and hasn’t quite been the same pitcher since. He had a 3.19 ERA in his career before going under the knife but has a 4.20 mark since then. He had a 27.3% strikeout rate prior to the surgery but has punched out just 19.4% of batters faced after.

He lingered in free agency this winter and didn’t land a deal until the Sox signed him in early April to a modest one-year deal with a $3MM guarantee. He went to the minors to build up his workload and was recalled in early May. The Sox were likely hoping for him to stabilized the rotation a bit by eating some innings and perhaps turning himself into a midseason trade candidate. That plan hasn’t worked out so far, as he has a 6.75 ERA through four starts and is now going on the injured list for at least a short spell.

The Sox have traded away many of their starters in recent years as part of their ongoing rebuild, including Dylan Cease, Lance Lynn and Lucas Giolito. This year, some of the guys they have tried have not worked out. Michael Soroka has been moved to the bullpen while Brad Keller was bumped off the roster entirely.

The Sox are left with a rotation core consisting of Garrett Crochet, Erick Fedde, Chris Flexen and Nick Nastrini. Crochet and Fedde have pitched well but Crochet will likely hit some kind of workload limit eventually, given how little he’s pitched in previous seasons. Fedde is on a two-year deal and will be a trade candidate this summer. Flexen is an impending free agent and would be a logical trade candidate as well, though his 5.69 ERA this year doesn’t give him massive appeal at the moment.

For now, Woodford will step in and make at least one start for the club. The 27-year-old was signed to a minor league deal in the offseason and has been pitching in Triple-A this year. He has logged 49 2/3 innings in his ten starts with a 5.26 ERA, 19.6% strikeout rate, 7.9% walk rate and 40.9% ground ball rate.

Prior to this year, he spent his entire career with the Cardinals. He threw 184 2/3 innings over the past four seasons with a 4.29 ERA. His 47.3% ground ball rate in that time was solid but his 15.1% strikeout rate well below par. He exhausted his option years in that stretch with St. Louis and they non-tendered him at the end of last season, which led to his deal with the Sox.

Since he’s out of options, the Sox will have to keep him on the active roster or else remove him from the 40-man entirely. If he manages to last on the roster all year, he can be retained beyond this season via arbitration. He came into 2024 with his service time count at three years and 48 days. If the club needs another starter down the line, Jonathan Cannon is on the 40-man but tossed six innings on Sunday. He wouldn’t have been available today but will perhaps get consideration going forward. Chad Kuhl and Touki Toussaint are non-roster options with some major league experience.

Peralta, 26, was just claimed off waivers from the Mariners two days ago. That brought him back to his original organization, as the Sox drafted him back in 2019 but lost him to the M’s off waivers in April of this year.

He made 16 appearances for the Sox last year with a 4.05 ERA in 20 innings. He struck out 20% of batters faced and walked 12.2%. With Triple-A Tacoma this year, he had a 9.24 ERA in 12 2/3 innings. His 20% strikeout rate and 13.3% walk rate with Tacoma were quite similar to last year’s major league work, but three home runs, a .361 batting average on balls in play and 57.7% strand rate pushed some extra runs across the plate.

The Sox were clearly still intrigued by their old friend and tried to bring him back, but the need for a roster spot nudged him off in short order. They will now have one week to trade him or pass him through waivers. He can still be optioned for the rest of this year and one more season as well. In the minor leagues in 2022, he tossed 62 innings with a 3.77 ERA, 29.2% strikeout rate, 8.5% walk rate and got grounders on roughly half the balls in play he allowed.

White Sox Claim Sammy Peralta Off Waivers From Mariners

By | at

The White Sox announced this afternoon that they’ve claimed left-hander Sammy Peralta off waivers from the Mariners and optioned him to Triple-A. The White Sox had an open space on their 40-man roster, so no corresponding move was necessary to bring Peralta into the fold.

Peralta, 26, returns to the south side of Chicago just a few weeks after being claimed off waivers from the club by Seattle. An 18th-round pick by the White Sox in the 2019 draft, Peralta ascended the minor league ladder to arrive in the big leagues with the club in 2023. In 16 appearances with the big league White Sox last year, the lefty pitched to a solid 4.05 ERA with a 4.41 FIP in 20 innings of work. While he struck out a decent 20% of batters faced during his time in the big leagues, control was a problem for the lefty as he surrendered free passes to 12.2% of his opponents. In 69 innings of work at the Triple-A level last year, Peralta managed to keep his walks to a minimum but had a problem with the home run ball, resulting in an ugly 5.09 ERA across his 29 appearances at the level that year.

Peralta’s lackluster minor league numbers and worrisome big league peripherals were enough to make him expendable for the White Sox as they sorted through their Opening Day roster crunch, and he was designated for assignment to make room for right-hander Jordan Leasure on the 40-man roster. That led the Mariners to claim him off waivers and stash him at the Triple-A level, but Peralta struggled to a 9.24 ERA in 12 appearances with the club and quickly found himself squeezed out of the organization in favor of righty Eduardo Salazar.

Fortunately for Peralta, the roster crunch in Chicago had lessened over the first two months of the season, and the club was able to add him back to their 40-man roster when the Mariners once again exposed him to the waiver wire. As such, he’s now set to return to his first MLB organization and act as optionable depth for the club capable of pitching multiple innings out of the bullpen alongside Prelander Berroa. Tim Hill, Tanner Banks, and Jared Shuster currently occupy the club’s bullpen as options from the left-hand side.

Mariners Claim Eduardo Salazar, Designate Sammy Peralta

By | at

The Mariners announced that they have claimed right-hander Eduardo Salazar off waivers from the Dodgers and assigned to Triple-A Tacoma. The Dodgers designated him for assignment earlier this week. In a corresponding move, left-hander Sammy Peralta has been designated for assignment.

Salazar, 26, signed a minor league deal with the Dodgers in the offseason and he was added to their roster in mid-April. He only made one appearance for the big league club, tossing two scoreless innings, spending most of his time this year on optional assignment.

He made seven starts for Triple-A Oklahoma City this year, tossing 33 2/3 innings with a 5.61 earned run average. He only struck out 13.7% of batters faced but limited walks to a 7.8% clip and got grounders on 58.6% of balls in play. With a .389 batting average on balls in play, it’s possible that luck played a role in how many runs he allowed to cross the plate.

Keeping the ball on the ground has been a feature of his game in the past as well. He made his major league debut with the Reds last year and had a 51.1% grounder rate in 12 1/3 innings, while also getting opponents to pound the ball into the dirt at a similar rate in the minors.

Salazar has worked both as a starter and a reliever in his career and could perhaps provide the Mariners with depth in both departments. He can be optioned for the rest of this year and for one more season as well. He also has just a handful of service days, meaning the Mariners can hang onto him for the foreseeable future as long as he continues to justify his roster spot.

Peralta, 26, was claimed off waivers from the White Sox in early April. He has made 12 appearances for Triple-A Tacoma but allowed 13 earned runs in 12 1/3 innings. His 20% strikeout rate, 13.3% walk rate and 36.8% ground ball rate are all subpar.

That poor performance has led to him being bumped off Seattle’s roster and they will now have one week to trade him or pass him through waivers. Perhaps some club will be interested based on his previous work. He made his major league debut last year with the White Sox and had a 4.05 ERA in 20 innings. His 5.09 ERA in Triple-A last year wasn’t especially impressive but he did strike out 23.1% of batters faced while walking just 6.4%.

Mariners Claim Sammy Peralta From White Sox

By | at

The White Sox announced that left-hander Sammy Peralta has been claimed off waivers by the Mariners. The southpaw was designated for assignment on Opening Day and has now been assigned to Triple-A Tacoma. The Mariners had two open spots on their 40-man roster, which is now at 39.

Peralta, 26, just made his major league debut with the Sox last year, frequently being shuttled between Triple-A and the big leagues. He ultimately tossed 20 innings in the majors with a 4.05 earned run average, striking out 20% of batters faced while walking 12.2%. He seemed to do a decent job of limiting damage, as his average exit velocity, barrel rate and hard hit rate were all better than average in that small sample.

He also tossed 69 innings over 29 appearances in Triple-A with a 5.09 ERA, though he likely deserved better. His 23.1% strikeout rate and 6.4% walk rate were both strong but a 59.2% strand rate seems to have hampered him, which is why his 4.21 FIP was almost a full run better.

The Mariners are currently a little bit snakebit in the bullpen, with Gregory Santos and Matt Brash trying to come back from injuries while Jackson Kowar is out for the year due to Tommy John surgery. They have two lefties on the big league roster in Gabe Speier and Tayler Saucedo but Peralta will give them a third option on their 40-man for when a need arises.

He still has two option years and less than a year of service time, so he can be a long-term depth piece for the club if he continues to hang onto that 40-man spot. The M’s have done a good job in recent years with unearthing hidden gems by grabbing fairly unheralded relievers and polishing them until they shine, so the club and Peralta will be hoping he is the latest point on that trendline.
