Mets' Robert Stock: Hard-luck loss in season debut
Rotowire
Stock (0-1) took the loss Sunday against the Marlins, allowing one run on three hits and no walks in five innings. He struck out four.
The Mets traded away Freddy Peralta earlier Sunday, but Stock filled in admirably during what was his first major-league start since 2021. The journeyman right-hander held Miami scoreless until the fifth inning, with the lone blemish on his line being a Joe Mack solo home run. New York has an open rotation spot now that Peralta has been dealt, and Stock figures to have earned himself another opportunity with the big-league club next week against Pittsburgh.

Mets' Robert Stock: Making first MLB start since 2021
Rotowire
The Mets selected Stock's contract from Triple-A Syracuse ahead of his scheduled start Sunday against the Marlins at Citi Field.
Stock will be making his 2026 MLB debut in what will be his first big-league start since the 2021 season. The 36-year-old right-hander has staged an incredible comeback from thoracic outlet syndrome, after he experienced symptoms of the nerve condition back in March while pitching for Team Israel in the World Baseball Classic. He was cleared to resume pitching in minor-league games June 19 and moved into the rotation earlier this month at Syracuse, where he allowed just two earned runs on five hits and two walks while striking out nine in 7.2 innings between two starts. Stock will now make the jump into the rotation at New York, though his opportunity to stick around with the big club in a starting role beyond Sunday will likely depend on whether at least one of Clay Holmes (fibula) and Freddy Peralta is moved ahead of Monday's trade deadline. Expect Stock to have a limited workload Sunday, as he hasn't thrown more than four innings or 66 pitches in any of his minor-league outings.

Mets' Robert Stock: Start with big club on tap
Rotowire
Stock will be called up from Triple-A Syracuse to start the Mets' series finale against the Marlins on Sunday, Andrew Tredinnick of The Bergen Record reports.
Stock is in line to make his first major-league appearance since June 8, 2025 and his first start in the majors since 2021. The 36-year-old right-hander opened the season on the shelf at Syracuse while recovering from thoracic outlet syndrome surgery, which he underwent in March. He was cleared to begin a rehab assignment June 19 and allowed two runs on five hits and two walks while striking out nine across 7.2 frames in two starts upon returning from Syracuse's injured list earlier this month. Stock will likely be in line for a limited workload Sunday and may be in store for just one start until the Mets get Clay Holmes (fibula) back from the 60-day IL.

Mets' Robert Stock: Debuts for Triple-A club
Rotowire
Stock (shoulder) struck out three and allowed one earned run on three hits and no walks across four innings Saturday in his 2026 debut for Triple-A Syracuse after being reinstated from the 60-day injured list.
While pitching for Team Israel in the World Baseball Classic back in March, Stock experienced shoulder discomfort and was later diagnosed with symptoms consistent with thoracic outlet syndrome. The 36-year-old later underwent surgery to address the condition, and he made rapid progress from a procedure that often entails a 3-to-6-month recovery. He kicked off a rehab assignment June 19 and received the green light to join the Syracuse rotation coming out of the All-Star break after he logged a 2.38 ERA, 0.62 WHIP and 17:1 K:BB in 11.1 innings over his five outings with High-A Brooklyn.

Mets' Robert Stock: Slated for TOS surgery
Rotowire
Stock (shoulder) said Sunday that he'll require surgery to address thoracic outlet syndrome and could be sidelined for the remainder of the season, Jon Heyman of the New York Post reports.
Stock is leaving the door open to pitch late in the season, but since he had been attending Mets camp on a minor-league deal, he's unlikely to surface in the majors at any point in 2026. The right-hander first experienced discomfort in his shoulder following his start Tuesday for Team Israel in an exhibition game against the Marlins.

Mets' Robert Stock: Dealing with shoulder discomfort
Rotowire
Stock experienced shoulder discomfort while playing with Team Israel in the World Baseball Classic and will undergo testing, Laura Albanese of Newsday reports.
Stock, entering his age-36 season, is on a minor-league contract with the Mets, and just weeks away from Opening Day, the veteran reliever began experiencing shoulder discomfort. The results of his testing should paint a clearer picture of how long he'll be sidelined, but according to Mark Feinsand of MLB.com, Stock won't pitch for Israel for the rest of the WBC.

Brewers' Robert Stock: Inks minors deal with Milwaukee
Rotowire
Stock signed a minor-league contract with the Brewers on Thursday that includes an invitation to spring training, per Adam McCalvy of MLB.com.
Stock spent the 2022 season with the Doosan Bears of the Korea Baseball Organization and pitched to an overall 3.60 ERA with 138 strikeouts (and 83 walks) in 29 starts covering 165 innings. Control problems plagued him throughout his time in MLB-affiliated ball, and it seems that those issues haven't been fully ironed out yet. The hard-throwing 33-year-old will probably be viewed as organizational bullpen depth by Milwaukee, though he did at least prove in the KBO that he can handle a starter's workload.

Robert Stock: Heading to KBO
Rotowire
Stock agreed to a one-year, $700,00 contract with the Doosan Bears of the Korean Baseball Organization on Tuesday, Jee-ho Yoo of the Yonhap News Agency reports.
Stock refused an outrighted assignment to Triple-A from the Mets in late October and elected free agency, and he'll continue his career in South Korea. The 32-year-old appeared in three games between the Mets and Cubs in 2021 and surrendered eight earned runs with a 9:9 K:BB over nine innings. However, he did find some MLB success as a rookie in 2018 with the Padres with a 2.50 ERA across 39.2 frames out of the bullpen.

Robert Stock: Elects free agency
Rotowire
Stock (hamstring) elected free agency after refusing an outright assignment to Triple-A Syracuse on Friday.
Stock made one start for the Cubs this season and two for the Mets before missing the majority of the second half with a strained right hamstring. Between that injury and his career 4.71 ERA in 72.2 major-league innings, Stock may be stuck looking for a minor-league deal heading into his age-32 season.

Mets' Robert Stock: Moved to 60-day IL
Rotowire
Stock (hamstring) was transferred from the 10-day injured list to the 60-day IL on Friday.
The transaction opens up a spot on the 40-man roster for Rich Hill, whom the Mets acquired from the Rays earlier Friday. In addition, the roster move means that Stock won't be eligible to return from the IL until late September, after he suffered what was an apparently severe right hamstring strain. The Mets are expected to get multiple rehabbing starting pitchers back from injuries before then, so in all likelihood, Stock will remain on the shelf for the rest of the season.

Stock exited Tuesday's game against the Reds due to a right hamstring issue, and he'll miss additional time after he was diagnosed with a strain Wednesday. It's not yet clear whether he'll be forced to spend more than the minimum of 10 days on the shelf, and the Mets haven't yet announced who could take his place in the rotation. Travis Blankenhorn and Nick Tropeano were recalled from Triple-A Syracuse as part of a corresponding move.
