Cubs Select Corbin Martin’s Contract
11:39PM: The Cubs officially announced Martin’s selection and Horton’s move to the 60-day IL.
11:04AM: The Cubs will select the contract of right-hander Corbin Martin prior to today’s game with the Mets, The Athletic’s Patrick Mooney reports. Cade Horton (who underwent Tommy John surgery yesterday) will be moved to the 60-day injured list to open up a 40-man roster spot for Martin, and the Cubs already had an open spot on their active roster after Daniel Palencia was placed on the 15-day IL yesterday.
Horton and Palencia are two of a whopping 10 pitchers on Chicago’s injured list, leaving the Cubs scrambling for extra arms. The situation has given Martin a path back to the majors after the righty signed a minor league deal back in January.
Martin is himself no stranger to injuries, as he missed the entirety of the 2020 season due to a TJ surgery and all of 2023 recovering from a lat tendon surgery. In the wake of the latter procedure, Martin spent all of 2024 in the minors before making his return to the Show to post a 6.00 ERA over 18 innings with the Orioles last season.
Over parts of four MLB seasons, Martin has a 6.54 ERA, 20.7% strikeout rate, and 12.8% walk rate across 75 2/3 innings with the Astros, Diamondbacks, and Orioles. Since his lat surgery, Martin has worked almost exclusively as a relief pitcher, but the role change hasn’t helped alleviate the control problems that have plagued Martin for much of his career.
Martin is out of minor league options, so Chicago would have to designate the righty for assignment and expose him to waivers before trying to send him back down to Triple-A via an outright. Given how the Cubs are hurting for pitching, Martin probably won’t be DFA’ed any time soon if he can provide decent results and eat a few innings out of the pen.
Cubs, Corbin Martin Agree To Minor League Deal
The Cubs are in agreement with right-hander Corbin Martin on a minor league contract, reports Marquee’s Lance Brozdowski. The 30-year-old will presumably get a non-roster invite to MLB camp.
Martin was on and off Baltimore’s big league roster throughout the 2025 season. He wound up throwing 18 innings, allowing 15 runs (12 earned). That actually lowered his career earned run average to 6.54 across 75 2/3 frames over parts of four seasons. Martin had similarly rough numbers with Triple-A Norfolk, allowing a 5.82 ERA in 34 appearances. He recorded an average 22.5% strikeout percentage while issuing walks at a huge 13.6% clip.
A former second-round pick of the Astros, Martin was a highly-regarded prospect whom the Diamondbacks acquired in the Zack Greinke trade. Injuries threw him off track. The 6’2″ righty underwent Tommy John surgery in 2019 and missed the entire ’23 season on account of a torn lat tendon. His control, which was solid enough early in his minor league career, has held him back at the upper levels. Martin has walked more than 12% of opponents in the big leagues and Triple-A alike.
The Cubs are intrigued enough by the raw stuff to give him a look on a non-roster deal. Martin’s heater sits in the 95-96 MPH range and he has a slider and curveball. It’s a good enough arsenal to miss bats but he’ll need to be around the strike zone more consistently to secure a spot in Craig Counsell’s relief group. Martin has exhausted his minor league option years, meaning the Cubs would need to keep him in the majors or expose him to waivers if they call him up.
22 Players Elect Free Agency
Now that the season is over, we’ll start seeing several players choose to become minor league free agents. Major League free agents (i.e. players with six-plus years of big league service time) will hit the open market five days after the end of the World Series, but eligible minor leaguers can already start electing free agency.
To qualify, these players must have been all outrighted off their team’s 40-man rosters during the 2025 season without being added back. These players also must have multiple career outrights on their resume, and/or at least three years of Major League service time.
We’ll offer periodic updates over the coming weeks about many other players hitting the market in this fashion. These free agent decisions are all listed on the official MLB.com or MILB.com transactions pages, for further reference.

Orioles Outright Corbin Martin
The Orioles announced that Corbin Martin accepted an outright assignment to Triple-A Norfolk. The right-hander cleared waivers after being designated for assignment on Tuesday. There has not yet been a resolution on Elvin Rodríguez, who was also DFA two days ago.
Martin spent a couple months in Tony Mansolino’s bullpen. He gave up 12 earned runs over 18 innings. Martin recorded a solid 25.8% strikeout rate but was plagued by walks and the home run ball. He gave up three runs apiece in his final two appearances against the Giants, though his defense let him down with a pair of errors in his last outing on August 31. While there was some poor luck in that appearance, Martin was pushed out when the O’s needed 40-man roster spots for Tyler Wells and Jorge Mateo.
Baltimore also ran Martin through outright waivers around the All-Star Break. He elected free agency that time but re-signed one day later. The 29-year-old decided not to try his luck on the open market this time around. It would’ve been too late into the season to be playoff eligible elsewhere. He’d likely have been looking at a minor league contract with a non-contender. It made more sense to stick with the O’s for the final weeks of the regular season. He’ll elect minor league free agency going into the offseason if the Orioles don’t call him back up this month.
Orioles Designate Corbin Martin, Elvin Rodríguez For Assignment
The Orioles announced that right-hander Tyler Wells and infielder/outfielder Jorge Mateo have been reinstated from the 60-day injured list. Catcher Maverick Handley has been optioned to Triple-A Norfolk in one corresponding active roster move. Right-hander Corbin Martin has been designated for assignment to open a second active roster spot and one 40-man spot. Righty Elvin Rodríguez, who was on optional assignment, has also been designated for assignment as the other corresponding 40-man move. The Wells activation was reported last week.
Mateo has been out since June due to a hamstring injury. The speedy utilityman hit just .180/231/.279 with a homer and 14 steals in 65 plate appearances prior to going on the injured list. The 30-year-old has never provided much in the way of offense, but even by his modest standards, that was well shy of the norm. In 1300 plate appearances from 2021-24, Mateo slashed .225/.271/.371 (79 wRC+) with 29 homers and 90 stolen bases. Mateo has long provided quality glovework at shortstop, though, and he can capably handle second, third or center field — all while providing elite speed on the bases.
This is the final guaranteed season the Orioles have with Mateo, though they can retain him via a club option for next season. They’d need to bring him back at a $5.5MM price point, however, which feels steep given the season he’s had and his prior lack of offensive production. There’s no buyout on the option, making it all the more likely that the O’s will turn it down, though there’s always a chance they’d try to bring him back at a lower rate.
Martin, 29, has been on and off Baltimore’s roster a few times this year. Around the transactions, he has tossed 18 innings, allowing 12 earned runs for an ERA of 6.00. He likely deserved better. His 10.1% walk rate was high but his 25.8% strikeout rate and 44.2% ground ball rate were solid figures. A .353 batting average on balls in play and 65.7% strand rate seemingly pushed some extra runs across. His 3.57 SIERA pointed to better run prevention going forward.
Regardless, the O’s have decided to move on again. Martin doesn’t have options and therefore can’t be easily sent back to the minors. With the trade deadline having passed, he’s destined for the waiver wire. If some club claims him, he can be controlled for four seasons after this one. He cleared waivers back in July, so it’s possible he’ll do so again. Last time he cleared, he exercised his right to elect free agency, which is another thing that could happen again in the coming days.
Rodríguez, 27, signed with the Brewers in January on the heels of some good results in Japan. Unfortunately, he hasn’t been able to have success in North America this year. The Brewers designated him for assignment in July, at which point the Orioles claimed him.
Between those two clubs, he has a 9.15 ERA in 19 2/3 major league innings. He has also tossed 40 1/3 Triple-A innings with a 4.46 ERA, 18.3% strikeout rate and 5.3% walk rate. Though the results haven’t been great, he does still have options, so perhaps he will appeal to a club looking for some extra depth in the minors.

Orioles Re-Sign Corbin Martin To Major League Deal
The Orioles announced that they have re-signed right-hander Corbin Martin to a major league deal. The O’s already had vacancies on their 40-man and active rosters, so no corresponding moves were necessary.
Martin was on the Baltimore roster as of a few days ago. On Sunday, he was designated for assignment to open an active roster roster spot for left-hander Grant Wolfram. Later that same day, just before gametime, Scott Blewett hit the IL with right elbow discomfort. Catcher David Bañuelos was recalled to take Blewett’s spot on the roster, presumably because he was with the club in a taxi squad capacity. Bañuelos was outrighted to Triple-A during the All-Star break. Martin cleared waivers and elected free agency but has quickly been re-signed, effectively taking the bullpen spot of Blewett.
Though he spent over a week on Baltimore’s roster, he only got to make one appearance. He tossed 1 1/3 scoreless innings back on July 2nd but then wasn’t used between that game and his DFA. Since he’s out of options, his grip on a roster spot is likely tenuous. However, the Orioles might sell some bullpen pieces prior to the deadline, with Seranthony Domínguez, Gregory Soto and Andrew Kittredge seeming like good candidates to be on the move. A trade of Félix Bautista is less likely but the O’s are at least listening to offers.
For now, he gets a major league job and will try to build on his season. Prior to getting called up at the start of July, he had tossed 32 1/3 Triple-A innings with a 5.29 earned run average. That probably disguises his performance a bit as his .306 batting average on balls in play, 68.4% strand rate and 17.9% home run to fly ball rate were all a bit to the unfortunate side. Meanwhile, he struck out 23% of batters faced with a 10.4% walk rate and 44.9% ground ball rate.
It wouldn’t be a surprise if he’s bumped off the roster again in the next few days but a greater path to innings could open up if the O’s pull the trigger on some trades. Perhaps he could hang on the roster into August or re-sign another time if he is bumped off again.

Corbin Martin Elects Free Agency
The Orioles announced Thursday that right-hander Corbin Martin, whom they designated for assignment this past Sunday, has cleared waivers and rejected an outright assignment to Triple-A Norfolk. He’s now a free agent.
The 29-year-old Martin appeared in one game for the O’s — his first time on a big league mound since the 2022 season with the D-backs. The former second-round pick was one of four players traded by the Astros to Arizona in 2019’s Zack Greinke trade. Martin was rehabbing from Tommy John surgery at the time of that trade and was ultimately unable to establish himself with the Diamondbacks. He’s pitched 57 2/3 innings in the big leagues to this point in his career (including his quick look with the O’s) and carries a 6.56 ERA, a 19.4% strikeout rate and a 13.4% walk rate.
The Orioles claimed Martin off waivers from the Brewers last June. He’s pitched 32 1/3 innings with a 5.29 ERA in Triple-A Norfolk this year. That includes a strong run from May 30 to the time of his call to the majors, during which he rattled off 12 innings of one-run ball with an 11-to-4 K/BB ratio. Overall, Martin has set down 23% of his opponents on strikes against a 10.4% walk rate. In parts of five Triple-A seasons, Martin has a 5.18 ERA, 23.1% strikeout rate and 11.8% walk rate in a total of 217 1/3 innings.
Orioles Designate Corbin Martin For Assignment
The Orioles announced this morning that they have recalled left-hander Grant Wolfram to the major league roster. Right-hander Corbin Martin was designated for assignment to make room for Wolfram on the club’s active roster. Baltimore’s 40-man roster now stands at 39 players.
Martin, 29, was a second-round pick by the Astros back in 2017 and received some attention as a top-100 prospect prior to the 2019 season. He underwent Tommy John surgery during the first half that year, and early in his recovery found himself traded to the Diamondbacks on the day of the trade deadline as part of the Zack Greinke blockbuster alongside Josh Rojas, Seth Beer, and JB Bukauskas. Martin didn’t return to a mound until 2021, and once he did so the results left much to be desired. He surrendered a 10.69 ERA in 16 innings of work during his first season with the Diamondbacks at the big league level, and while he showed some signs of improvement during his age-26 season in 2022 he suffered a number of additional injuries.
That includes a lat tear in his shoulder that required surgery and cost him his 2023 campaign. Martin was ultimately designated for assignment by the Snakes in early 2024, and after a brief stint in the Brewers’ minor league system last year he found himself claimed off waivers by the Orioles last May. He pitched at Triple-A for Baltimore’s Norfolk affiliate last year and was eventually removed from the 40-man roster, but remained with the organization and was brought back up to the majors earlier this month. This latest stint in the majors proved to be a brief one, as he remained on the roster for less than two weeks and made just one appearance. The appearance was an impressive one, however, as he struck out two and allowed just one hit in 1 1/3 innings of work against the Rangers.
Going forward, the Orioles will have one week to either work out a trade involving Martin or attempt to pass him through waivers. Should he clear waivers successfully, he would have the opportunity to either accept an outright assignment to the minor leagues or elect free agency in search of a better opportunity elsewhere. It wouldn’t be a shock to see some team take a chance on him now that he’s healthy, though his 5.29 ERA at Triple-A this year still raises some questions about his effectiveness even after his strong return to the majors earlier this month. As for Wolfram, the rookie made his big league debut with the Orioles earlier this year and has a 31.3% strikeout rate in three appearances at the big league level so far this season. With Keegan Akin on the injured list, Wolfram’s return to the bullpen should take some pressure off of fellow lefty Gregory Soto going forward.
Orioles Designate Matt Bowman For Assignment, Select Corbin Martin
The Orioles announced today that they have recalled right-hander Yennier Cano and selected the contract of right-hander Corbin Martin. In corresponding moves, they have designated right-hander Matt Bowman for assignment and placed left-hander Keegan Akin on the 15-day injured list, retroactive to July 1st, due to left shoulder inflammation.
Martin, 29, was a top-100 prospect with the Astros and D-backs several years ago. He was one of four players who went from Houston to Arizona in the 2019 Zack Greinke trade, but while he saw MLB time with both the ‘Stros and Snakes, he’s never really found his footing. Martin, who was on the mend from Tommy John surgery when he was included in that trade, has pitched 57 2/3 innings in the majors and recorded only a 6.71 ERA. He’s fanned 19% of his opponents against a 13.6% walk rate and been far too susceptible to home runs, yielding an average of 2.50 big flies per nine frames.
The Orioles claimed Martin off waivers from the Brewers last June. (Milwaukee had claimed him from Arizona a couple months earlier.) He was eventually removed from the 40-man roster but now returns after pitching 32 1/3 innings with a 5.29 ERA in Triple-A Norfolk this year. He’s set down 23% of his opponents on strikes against a 10.4% walk rate. It’s not a great set of season-long numbers, but Martin has been doing his best work of late. Dating back to May 30, he’s pitched a dozen innings and held opponents to just one run on three hits and four walks with 11 punchouts. If he gets into a game, it’ll be his first time on a major league mound since 2022.
Bowman, 34, has now been designated for assignment by the Orioles three times since Opening Day. He’s accepted a pair of outright assignments to Norfolk previously. The right-hander has appeared in 19 games for Baltimore this season but pitched to a middling 5.79 earned run average. In 23 1/3 innings, he’s fanned only 15.7% of his opponents. Bowman’s 5.6% walk rate is excellent, but he’s also plunked a pair of batters and served up four home runs (1.54 HR/9).
In parts of seven big league seasons, Bowman has pitched for seven different teams — including four in 2024 alone. He’s compiled 239 1/3 innings in the majors and recorded a collective 4.32 ERA, 18.7% strikeout rate and 8% walk rate. The O’s will trade him or place him on outright waivers within the next five days. If his prior DFAs this year are any indication, there’s a good chance Bowman will clear waivers and agree to head back to Norfolk while he awaits another call to Camden Yards.
Cano was only optioned to Norfolk last week, but he can return in under the 10-day minimum stint for an optional assignment because he’s replacing the injured Akin. The 30-year-old Akin has been an important part of the Orioles’ bullpen this season, pitching 38 innings of 3.32 ERA ball with a 23.3% strikeout rate and an uncharacteristically high 11% walk rate. Entering the season, Akin had just a 7.4% walk rate in more than 300 MLB frames.
Akin has cut back on the free passes lately — none in his past 4 2/3 innings — but Akin was roughed up for three runs (two earned) in an inning of work his last time out. There was no velocity drop or major signal that the left-hander’s shoulder was giving him trouble, but today’s IL placement means he’ll sit through at least the All-Star break as he mends.
Orioles Claim Corbin Martin, Recall Kyle Stowers
1:23pm: Baltimore will option top outfield prospect Heston Kjerstad to Norfolk to make room for Stowers, tweets Ghiroli.
12:50pm: The Orioles announced Monday that they’ve claimed right-hander Corbin Martin off waivers from the Brewers. He’s been optioned to Triple-A Norfolk. Baltimore’s 40-man roster had an open spot and is now at capacity. It seems as though this will be just one of multiple moves for Baltimore today, as Britt Ghiroli of The Athletic also reports that the O’s are calling up outfielder Kyle Stowers from Norfolk. The team has yet to announce that move or any corresponding transactions.
Martin, 28, was a second-round pick of the Astros in 2017 who went from Houston to Arizona as one of the headline pieces in 2019’s Zack Greinke blockbuster. His career trajectory has been impacted by injuries — Tommy John surgery most notably. Martin pitched in the big leagues in 2019, 2021 and 2022 but has just 57 2/3 MLB frames under his belt. He’s limped to a 6.71 earned run average in that time, fanning a well below-average 19% of his opponents against a weighty 13.6% walk rate.
Entering that 2019 season in which he was traded, Martin ranked 78th and 81st on the respective top-100 prospect lists published by Baseball America and MLB.com. He was touted as a high-probability mid-rotation arm, having just wrapped up a season that saw him toss 122 innings of 2.51 ERA ball with a 25.5% strikeout rate and 7.3% walk rate between High-A and Double-A. He underwent Tommy John surgery in early July and was included in the aforementioned Greinke trade just weeks later — a deal that was completed and filed just seconds before the deadline. Martin missed the entire 2020 season as a result and hasn’t looked the same in any of his post-surgery seasons.
In parts of three seasons since that ligament reconstruction, Martin has pitched to an ERA north of 6.00 in Triple-A. Hitter-friendly Pacific Coast League caveat notwithstanding, that type of performance simply doesn’t measure up to his prior promise. He was tagged for 21 runs in 16 big league innings with Arizona in 2021, posted a 6.08 ERA in 77 frames with the D-backs in 2022, and missed the entire 2023 season after suffering a torn tendon in his latissimus dorsi during spring training.
More concerning than the poor ERA marks was the evaporation of Martin’s command post-elbow surgery. The 7.3% walk rate he posted in 2018 feels like a distant memory. Martin issued a free pass to 11.4% of his opponents in 2021-22 (MLB and Triple-A combined). He walked a massive 13 of 50 opponents thus far in 2024 (26%).
All of those struggles aside, it’s not entirely surprising to see the Orioles claim Martin. Baltimore general manager Mike Elias was the Astros’ scouting director in 2017 when they selected Martin with the 56th overall pick in the draft and paid him a $1MM signing bonus. Elias is keenly familiar with Martin — both as the pitcher he was shaping up to be prior to his injuries and as a person.
As for Stowers, he’ll return to the big leagues for a third straight season. He hit fairly well in a small sample of 98 plate appearances in 2022 before floundering through a 2-for-30 stretch at the plate in the majors last season. The lefty-swinging 26-year-old is out to a .240/.315/.541 start in Norfolk this season and has already socked 11 home runs in 165 trips to the plate.
Contact remains something of an issue, as Stowers is still punching out in just shy of 27% of his plate appearances against a 7.9% walk rate. Nonetheless, he’ll add some left-handed pop to Baltimore’s outfield mix for the time being. Stowers has spent the bulk of his pro career in right field but has experience in all three spots and has spent more time in center this year (115 innings) than either right field (89) or left field (54).
