Red Sox Acquire Joe La Sorsa
6:41pm: Boston announced the trade but has yet to reveal the corresponding move.
5:20pm: The Pirates are going to trade left-hander Joe La Sorsa to the Red Sox, reports Ari Alexander of 7News Boston. The Bucs will get cash in return, per Alex Speier of The Boston Globe. It was reported a few days ago that the southpaw was triggering an upward mobility clause in his minor league deal. Alexander says that La Sorsa will be with the Sox in New York tomorrow as they kick off a series against the Yankees. Boston will need to open a 40-man roster spot for La Sorsa.
La Sorsa, 28, will be appearing in his fourth straight major league season once he gets into a game with the Sox. From 2023 to 2025, he pitched for the Rays, Nationals and Reds, posting a 5.21 earned run average in 57 innings.
He signed a minor league deal with the Pirates in the offseason and has been pitching for Triple-A Indianapolis. He has thrown 26 innings with a 3.46 ERA. His 21.2% strikeout rate is around average while his 5.8% walk rate and 47.9% ground ball rate a few ticks better than par.
The lefty triggered an upward mobility clause in his deal at the end of spring training. The way such clauses work is that the player must be offered to the 29 others teams in the league. If any of them want to give the player a roster spot, the signing team has to either trade him or give him a roster spot themselves. If they all pass, he will stay with the signing team. La Sorsa stayed with the Bucs in late March, suggesting all clubs passed on him at that time. In this case, the Sox have signed up.
Boston has three lefties in the bullpen, though Aroldis Chapman is the closer. That leaves Jovani Morán and Danny Coulombe as the lefty options for situations before the ninth inning. Coulombe spent about three weeks on the injured list due to cervical spasms and has a 6.55 ERA around that IL stint. Morán has a much better 3.19 ERA but has gotten some help from a fortunate .197 batting average on balls in play and 85.2% strand rate. La Sorsa will give the Sox another option in the southpaw relief corps.
The Sox don’t have a lot of flexibility in their current bullpen mix. Of their eight relief arms, only Justin Slaten and Greg Weissert are optionable, but those are two of their two setup arms. La Sorsa himself is optionable but, as mentioned, he is expected to be with the big league club in the Bronx tomorrow. Perhaps Coulombe will be designated for assignment, as that would open up a spot on both the active and 40-man rosters for La Sorsa. Other options for that kind of move would be Tyron Guerrero and Ryan Watson, who both have ERAs north of 5.00 at the moment.

Joe La Sorsa To Exercise Upward Mobility Clause In Pirates Contract
For the second time this year, Joe La Sorsa will trigger an upward mobility clause in his minor league deal with the Pirates. 7 News’ Ari Alexander reports that La Sorsa will exercise the clause tomorrow, and the Pirates will then have to offer the left-hander to the other 29 big league clubs.
If any other team is willing to give La Sorsa a roster spot, the Pirates are required to trade La Sorsa to an interested team, or add them to their own active roster. If none of the 29 teams are interested, La Sorsa will remain in Pittsburgh’s minor league system.
The two sides already went through this process at the end of Spring Training, when La Sorsa exercised his clause and went unclaimed. The Bucs haven’t felt compelled to select La Sorsa’s contract over the last two months, though he has a respectable 3.60 ERA, 5.9% walk rate, and 46.4% grounder rate rate over 25 innings with Triple-A Indianapolis.
La Sorsa has only a 20.8% strikeout rate, which about matches his moderate swing-and-miss ability over his pro career. After breaking into the majors with Tampa Bay in 2023, La Sorsa has a 5.21 ERA, 17.5K%, and 6.3BB% over 57 career innings with the Rays, Nationals, and Reds. The Mets inked La Sorsa to a minors deal last September that didn’t result in any big league playing time, and La Sorsa became a minor league free agent at season’s end before joining the Pirates.
Between closer Gregory Soto, Mason Montgomery, and Evan Sisk, Pittsburgh has been getting good results from the left-handed complement of its relief corps. Most teams generally don’t have more than three southpaws in the bullpen, so La Sorsa might not have a path to the Pirates’ roster. That said, the Bucs do have an open spot on the 40-man roster and even on their 26-man, as Cam Sanders was optioned back to Triple-A following a one-game cup of coffee in today’s 9-3 win over the Twins.
Another club with more of a pressing need for left-handed depth could have interest in La Sorsa. He has a minor league option remaining, so he has value for teams looking for bullpen arms that can be shuffled back and forth (up to five times) from Triple-A.
Joe La Sorsa To Stay With Pirates
March 25th: La Sorsa went unclaimed and will stay with the Pirates as non-roster depth, per Alexander.
March 22nd: La Sorsa has been told he won’t be breaking camp with the Pirates, so he’ll be triggering his clause tomorrow, Ari Alexander reports.
March 17th: Left-hander Joe La Sorsa has an upward mobility clause at the end of spring training in his minor league deal with the Pirates, reports Ari Alexander of 7 News Boston. If he triggers that clause, he’ll be offered up to the other 29 clubs. If any of them are willing to give him a roster spot, then the Pirates have to either give him a roster spot themselves or trade him to another club that will. If no club offers him a roster spot, then he can be sent to the minors as non-roster depth.
La Sorsa, 28 in April, agreed to a minor league deal with the Bucs right as free agency was beginning in early November. He hasn’t spent much time in camp because he joined the Italian team for the World Baseball Classic. The Azzurri went on a Cinderella run that just ended last night when they were eliminated by Venezuela in the semifinals. The lefty made four appearance for Italy, logging 2 2/3 innings, allowing two earned runs via two hits and one hit-by-pitch while striking out four.
His major league track record consists of 57 innings thrown for the Rays, Nationals and Reds over the past three years. In that time, he has a 5.21 ERA, 17.5% strikeout rate, 6.3% walk rate and 39.2% ground ball rate. In 2025, he only made five appearances in the majors. He spent most of the year in Triple-A, posting a 2.59 ERA in 48 2/3 innings. His 21.2% strikeout rate and 42.1% ground ball rate at that level were close to average but he walked 13% of batters faced.
With the upward mobility clause, La Sorsa will get a major league roster spot as long as one of the 30 clubs is willing to give him one, whether that’s the Pirates or not. The Bucs should have Gregory Soto and Mason Montgomery as their two primary lefties in the bullpen. Evan Sisk is also on the roster but he has already been optioned, so he should start the season in Triple-A. If La Sorsa does get a roster spot somewhere, he still has a minor league option remaining.

Pirates To Sign Joe La Sorsa
The Pirates are expected to sign left-hander Joe La Sorsa, reports Jon Morosi of MLB Network. It’s a minor league deal with an invite to MLB Spring Training.
La Sorsa has pitched in parts of three MLB seasons with three different teams. He debuted with the Rays in 2023. La Sorsa was most recently with Cincinnati. He made five appearances with the Reds last season.
Tampa Bay drafted La Sorsa in 2019. He tossed 36 1/3 innings at Low-A that same year. La Sorsa delivered a 3.60 ERA across 31 appearances in 2021, striking out nearly a batter per inning. He took a step forward the following season, with an elite 36.3% strikeout rate leading to a Double-A promotion. Minor leaguers hit just .191 against La Sorsa in 2022. He posted a 2.33 ERA across a career-high 73 1/3 innings.
La Sorsa was designated for assignment after just two games with the Rays in 2023. He was quickly scooped up by the Nationals via waiver claim. La Sorsa logged 23 appearances out of Washington’s bullpen that season. He limited walks and kept the ball in the yard, but finished with a 4.76 ERA. After a half-season with Triple-A Rochester, La Sorsa was back with the Nationals in August of 2024. He delivered similarly tepid results and was released in the offseason.
Cincinnati had La Sorsa traveling back and forth from Triple-A Louisville to Great American Ball Park all summer. He was recalled to the big-league club on four separate occasions, including three times in June. La Sorsa was knocked around for eight earned runs in 6 2/3 innings with the Reds. He allowed four home runs in his five outings with the team.

Mets Sign Joe La Sorsa To Minors Contract
1:12PM: The Mets have signed La Sorsa to a minor league contract, MLB.com’s Anthony DiComo reports. La Sorsa will provide some left-handed bullpen depth for a New York team that has had a revolving door of relievers going up and down from Triple-A all season.
11:59AM: Left-hander Joe La Sorsa has chosen to become a free agent instead of accepting an outright assignment to the Reds’ Triple-A affiliate, according to reporter Charlie Goldsmith. Cincinnati designated La Sorsa for assignment earlier this week, and after he cleared waivers, La Sorsa had the ability to decide his next step since he has been previously outrighted in his career.
Over his first two MLB seasons, La Sorsa posted a 4.47 ERA over 50 1/3 innings and 41 games with the Rays and Nationals in 2023-24. Cut loose by the Nats over the offseason, the southpaw caught on with Cincinnati on a minors contract, and that contract was selected to the active roster in early June.
The Reds made only sporadic use of La Sorsa and frequently only kept him in the majors for brief stints, and the up-and-down usage may have contributed to his ugly 10.80 ERA over five appearances and 6 2/3 innings. Within that small sample size, La Sorsa was tagged for four home runs.
Time is running out on La Sorsa’s chances of landing a big league job with another team before 2025 is over, yet signing elsewhere on another minors deal might at least give the lefty a head start on the offseason. La Sorsa has another minor league option year remaining, and clubs might be intrigued by La Sorsa’s career 2.88 ERA over 134 1/3 Triple-A innings. These excellent bottom-line results come with a modest 19.05% strikeout rate, and La Sorsa’s walk rate also drastically spiked upward when pitching with Triple-A Louisville this season.
Reds Designate Joe La Sorsa For Assignment
The Reds announced Tuesday that they’ve designated left-hander Joe La Sorsa for assignment and selected the contract of fellow southpaw Reiver Sanmartin from Triple-A Louisville. Cincinnati also optioned lefty Sam Moll to Louisville. Additionally, outfielder/first baseman Connor Joe has accepted an outright assignment to Triple-A after clearing waivers, per C. Trent Rosecrans of The Athletic.
La Sorsa, 27, has pitched just 6 2/3 innings with the Reds this year after signing a minor league deal in the offseason. He’s been tagged for eight earned runs on 13 hits (four homers) and a pair of walks with two strikeouts in that small sample. That’s clearly not an exciting line for any pitcher, but the lefty has been far better in Triple-A, where he’s pitched 44 2/3 frames with a 2.82 earned run average. La Sorsa’s 21.1% strikeout rate and 13.4% walk rate in Louisville both leave something to be desired, however.
This year’s brief look with the Reds brought La Sorsa’s career totals in the majors to 57 innings with a 5.21 ERA, a 17.5% strikeout rate and a 6.3% walk rate. He’s previously suited up for the Rays and Nationals. While the big league track record is limited, La Sorsa has a 2.88 ERA in three Triple-A seasons (134 1/3 innings). He sits 91-92 mph with his sinker and complements that pitch with an upper-70s slider and a seldom-used changeup in the mid-80s. Now that he’s been designated for assignment, La Sorsa will head to waivers and be available to all 29 other teams. He’ll have a minor league option remaining next season.
Sanmartin, 29, is a familiar face for Cincinnati fans. He spent considerable time with the Reds in the majors from 2021-23, picking up 82 2/3 innings out of the bullpen. Sanmartin was hit hard in the majors, yielding a 5.77 ERA and a .289/.366/.450 batting line to his opponents across those three seasons. He’s posted a 4.27 ERA with a strikeout per inning in parts of three Triple-A campaigns, although this year’s 15 runs in 18 1/3 innings (7.36 ERA) don’t exactly portend a breakout.
The Reds cycled through four relievers yesterday and have had both Emilio Pagan and Tony Santillan work on back-to-back days already. Starter Nick Lodolo was scratched from today’s start due to illness, the team announced earlier in the day, leaving reliever Scott Barlow to start what will be a bullpen game. With that in mind, it’s not surprising to see them bring up a fresh arm — particularly one who’s stretched out for multi-inning work. Each of Sanmartin’s past four relief appearances has been for two or more innings, and he last pitched two frames on Aug. 29. He should be fresh for the day and could give the Reds two to three innings in relief of Barlow at some point.
As for Joe, he’s been with the Reds since early May. Originally signed by the Padres to a one-year, $1MM contract over the winter, the veteran 33-year-old has struggled to a .186/.263/.243 slash in 80 plate appearances between the two teams this season. The Reds have only used Joe sparingly, giving him 70 big league plate appearances since his May 9 acquisition. He’s struggled with similar rate stats in a similar sample of Triple-A at-bats this season.
Given this year’s poor performance in the upper minors and in the majors, it’s not surprising that no team placed a claim on Joe. It’s also unsurprising that he accepted the outright assignment. Joe has the three years of service needed to reject an outright assignment but does not have the five years required to reject an outright assignment and retain the remainder of his guaranteed money. Rejecting the assignment would’ve meant forfeiting the remaining $150K or so on his contract, so he’ll stick with the Reds for the rest of the year. As a player with more than three years of service who’s been removed from the 40-man roster, he’ll have the right to become a free agent at season’s end (unless he’s added back to the 40-man roster in the interim).
Reds Designate Jake Fraley For Assignment
The Reds announced this morning that they’ve designated outfielder Jake Fraley for assignment. Outfielder Will Benson was recalled to replace Fraley on the active roster. Right-hander Connor Phillips was also recalled to the MLB roster after the club optioned southpaw Joe La Sorsa to Triple-A last night.
Fraley, 30, began his career with the Mariners and was shipped to Cincinnati as part of the trade that sent Eugenio Suarez and Jesse Winker to Seattle. Since making his Reds debut in 2022, Fraley has been a roughly league average bat for the club. He’s hit .260/.336/.421 (105 wRC+) in 362 games for the club over the past four seasons and has never posted a wRC+ below 96 over a full season. He’s proven to be a solid baserunner as well, with 20-steal campaigns in both 2023 and ’24, though his defense has left him mostly limited to being a middling defender in the outfielder corners.
The biggest flaw in Fraley’s game is his massive platoon split, however. He’s virtually unplayable against lefties, with a .187/.263/.260 (44 wRC+) slash line against southpaws in 137 plate appearances during his time with the Reds. That’s offset by his solid .269/.346/.441 (113 wRC+) line against right-handed pitchers, of course, but Fraley is also in a 1-for-17 slump since the start of August and is hitting a lackluster .226/.305/.377 (83 wRC+) dating all the way back to June 20. That’s not substantially better than Benson, who sports an 80 wRC+ in 201 plate appearances this year. Perhaps the Reds are hoping that giving Benson opportunities down the stretch will get him into position to take over Fraley’s role as a left-handed platoon outfielder for 2026, when Fraley would’ve been due a raise on his $3.125MM salary for 2025 via arbitration and likely found himself non-tendered come November.
As for Phillips, the righty was once a consensus top-100 prospect but suffered a brutal season at Triple-A last year as he walked 15.3% of his opponents in 19 starts. He’s converted to relief this year and done better for himself with a 2.84 ERA in 38 innings, though his 14.6% walk rate remains elevated. He’s made just four appearances at the big league level this year but will now get an opportunity to try and harness his high-octane stuff as the Reds shuffle out La Sorsa, who surrendered a three-run homer to infielder Andruw Monasterio in the 11th inning of yesterday’s brutal 6-5 loss to Milwaukee.
Reds Select Sam Benschoter
The Reds announced Tuesday that they’ve selected the contract of right-hander Sam Benschoter from Triple-A Louisville. Cincinnati also recalled southpaw Sam Moll from Louisville. Left-hander Joe La Sorsa and righty Connor Phillips were optioned to Triple-A in their place. The Reds already had an open 40-man roster spot after releasing Jeimer Candelario. Their 40-man roster is now at capacity.
Benschoter, 27, was an undrafted free agent out of Michigan State back in 2021. He’s spent the past four seasons climbing Cincinnati’s minor league ranks, reaching Triple-A late last season. That first run at the top minor league level didn’t go well, but the 6’3″, 215-pound righty has had a better showing in 2025. Benschoter has pitched 51 innings — 17 relief appearances, four starts — and logged a 4.06 ERA with a 21.6% strikeout rate, 6.4% walk rate and 51% ground-ball rate.
Benschoter relies heavily on a four-seamer that’s averaged 93.4 mph in 2025, combining that pitch with a sinker, slider, cutter and seldom-used curveball to round out his arsenal. He worked primarily out of the rotation in the lower minors but moved into more of a hybrid role in 2024. He’s progressively moved more and more toward a multi-inning relief role in 2025. Even in his four “starts” this season, Benschoter has pitched a combined 12 1/3 innings. He’s most commonly been used in relief for two to four innings at a time.
Top prospect Chase Burns lasted only one-third of an inning in yesterday’s drubbing at the hands of the Red Sox, forcing the Cincinnati bullpen to cover the rest of the game. The Reds turned to Brent Suter and the now-optioned La Sorsa and Phillips for two-plus innings apiece. All three men threw at least 31 pitches. That understandably prompted some moves to freshen up the relief corps. If today’s game gets out of hand one way or another, Benschoter would seemingly be an option for a long relief stint. He last pitched a week ago and should be able to cover several innings if need be.
Reds To Add Joe La Sorsa To 40-Man Roster
The Reds intend to select lefty reliever Joe La Sorsa onto their 40-man roster, reports Ari Alexander of KPRC 2. He’ll remain with Triple-A Louisville, as the team will immediately option him back to the minors. Cincinnati has an open 40-man spot after last week’s Alexis Díaz trade, so there’s no need for a corresponding move.
La Sorsa triggered an upward mobility clause in his minor league deal over the weekend. That required the Reds to gauge interest from other teams in selecting his contract. If any other team were willing to do so, Cincinnati would either have to carry him on their own 40-man roster or let him join another team. They took the former approach to keep him in the organization, but he still has two minor league option years and can remain in Louisville through the end of next season if he holds his 40-man spot for that long.
The 27-year-old La Sorsa made 41 MLB appearances with the Rays and Nationals between 2023-24. He owns a cumulative 4.47 earned run average across 50 1/3 innings. La Sorsa’s sinker has sat in the 87-88 MPH range during his big league tenure. The lack of velocity has contributed to a below-average 19.2% strikeout rate. His velocity is up across the board this year in Triple-A. His sinker is sitting closer to 92 MPH, while he has pushed his sweeping slider from the mid-70s to north of 78 MPH on average. He’s running his four-seamer up to 94 MPH, though he has continued to lean on the sinker as his main pitch.
The uptick in stuff intrigued the Reds and presumably at least one other team. It hasn’t resulted in improved results, though. La Sorsa owns a 3.92 ERA with matching 16.1% strikeout and walk rates across 20 2/3 frames for Louisville. He’s getting whiffs on only 7.1% his offerings, which is two percentage points lower than last year’s Triple-A swinging strike rate. La Sorsa had managed a 2.25 ERA with much better command over 56 innings in the Nats’ system last season. The Reds will give him some more time to try to establish the command of his bigger stuff.
