The Chicago Cubs have bolstered their bullpen by selecting the contract of right-handed pitcher Corbin Martin, moving him from Triple-A Iowa to the major league roster. The transaction comes after right-hander Daniel Palencia was placed on the 15-day injured list due to right shoulder inflammation, as confirmed by the team on Saturday, June 15, 2024. Martin’s promotion adds depth to a relief corps navigating a stretch of heavy usage early in the season.
Martin, a 29-year-old right-hander, made his Cubs debut that same afternoon against the St. Louis Cardinals at Wrigley Field, entering the game in the seventh inning with the Cubs trailing 4-2. He recorded one inning of operate, allowing one hit and striking out two batters while walking none. The move reflects the club’s ongoing effort to balance performance and health as they maneuver through a competitive National League Central race.
The decision to activate Martin underscores the Cubs’ reliance on their Triple-A affiliate as a pipeline for ready contributors. Iowa Cubs manager Marty Pevey confirmed prior to the promotion that Martin had been throwing consistently in his last five outings, posting a 2.45 ERA over 22 innings with 24 strikeouts and only four walks. His ability to throw strikes and generate ground balls made him a logical choice for high-leverage situations, especially with the backend of the bullpen needing reinforcement.
Corbin Martin’s Path Back to the Majors
Martin’s return to the major leagues marks another chapter in a career defined by perseverance. Originally drafted by the Arizona Diamondbacks in the third round of the 2016 MLB Draft out of Campbell University, Martin made his MLB debut with Arizona in 2018. After stints with the Diamondbacks, Seattle Mariners, and Cincinnati Reds, he signed a minor league contract with the Cubs in February 2024, receiving an invitation to spring training.
Though he did not make the Opening Day roster, Martin remained a consistent performer in Triple-A, where he worked primarily as a multi-inning reliever and occasional spot starter. His season with Iowa began in early April, and by mid-June, he had appeared in 24 games, logging 38 innings with a 3.30 ERA and 41 strikeouts. Notably, he held opponents to a .210 batting average and induced ground balls at a 52% rate — metrics that align with the Cubs’ current emphasis on inducing weak contact.
According to Baseball Savant, Martin’s four-seam fastball averages 92.3 mph, while his slider generates 14.2 inches of horizontal break, ranking in the 78th percentile among right-handed relievers. His ability to miss bats — particularly against left-handed hitters, whom he has held to a .182 average this season — adds versatility to a bullpen that has leaned heavily on right-handed options.
Daniel Palencia’s Injury and Timeline
The move to place Daniel Palencia on the injured list was made official on June 15, 2024, following an evaluation by the Cubs’ medical staff. Palencia, 25, had been experiencing discomfort in his right shoulder during his last two appearances, prompting the team to act preventatively. He last pitched on June 12 against the Pittsburgh Pirates, throwing 1.1 innings in a high-leverage spot before being removed due to fatigue, and tightness.
Palencia, a Rule 5 Draft selection from the 2022 offseason, had emerged as a reliable middle-relief option for Chicago in 2024. Prior to his injury, he held a 2.89 ERA over 28 appearances, with 34 strikeouts and a 1.18 WHIP. His ability to throw multiple innings and handle high-leverage situations had made him a key part of manager Craig Counsell’s early-season plan.
The Cubs have not disclosed a specific return timeline for Palencia, but shoulder inflammation typically requires a minimum of 10–14 days of rest before a gradual throwing program begins. The team emphasized that the move is precautionary, aiming to avoid a more significant setback. As of June 20, Palencia has begun light tossing exercises at the team’s spring training facility in Mesa, Arizona, though no official rehabilitation assignment has been announced.
Bullpen Dynamics and Usage Patterns
With Palencia sidelined, the Cubs’ bullpen has seen increased workload from remaining options such as Nate Pearson, Tucker Barnhart, and rookie reliever Javier Assad. Pearson, who was activated from the injured list earlier in June, has logged 12 appearances since May 28, averaging 1.2 innings per outing. Assad, meanwhile, has been used in back-to-back games on three separate occasions in June, raising concerns about long-term durability.
Counsell acknowledged the strain during a pre-game press conference on June 18, stating, “We’re trying to spread the load, but when someone goes down, we have to lean on the guys who are ready. Corbin gives us another arm that can go multiple innings if needed, and that’s invaluable.”
The Cubs’ bullpen has ranked in the bottom third of the National League in reliever ERA (4.62) and inherited runner scoring rate (48.3%) through June 20. But, their strikeout rate of 9.4 per nine innings ranks eighth in the league, indicating that while damage prevention remains a concern, the ability to miss bats is present.
Martin’s addition allows Counsell to mix and match based on matchups, particularly in late-inning scenarios where left-handed hitters are due up. Martin has held lefties to a .190 average in Triple-A this season, compared to .230 against righties — a split that could prove useful in close games.
Roster Moves and 40-Man Implications
To make room for Martin on the 40-man roster, the Cubs transferred infielder Nick Schwindel to the 60-day injured list on June 15. Schwindel, who has been sidelined since early May with a left oblique strain, was already unlikely to return before the All-Star break. The move cleared space without requiring a designation for assignment or loss of control over another player.
Martin remains on minor league contract terms, meaning he is not yet on the 40-man roster. His promotion was achieved through a standard contract select, which does not require 40-man space. However, if the Cubs intend to preserve him beyond a short stint, they will need to make a corresponding move to add him to the 40-man roster, potentially involving a DFA or trade.
As of June 20, Martin has not been added to the 40-man roster, indicating the Cubs may view his promotion as temporary — possibly a bridge until Palencia’s return or until another option emerges from the minors or trade market.
Looking Ahead: Bullpen Health and Trade Deadline Considerations
The Cubs’ front office, led by president of baseball operations Jed Hoyer, has indicated that bullpen depth will be a priority as the July 30 trade deadline approaches. While the team remains in contention for a National League Wild Card spot — sitting 3.5 games behind the Milwaukee Brewers as of June 20 — their relief pitching has been identified as an area needing improvement.
Internal options such as Peyton Remy and Hugh Bowman are being monitored in Triple-A, both of whom have posted ERAs under 3.50 with high strikeout rates. Externally, the Cubs have been linked in speculative reports to relievers like Tanner Scott of the Miami Marlins and Andrew Chafin of the Detroit Tigers, though no concrete discussions have been confirmed.
For now, the focus remains on getting healthy and maximizing current assets. Palencia’s progression will be monitored closely, with his next medical evaluation expected around June 25. If he continues to respond well to rest and treatment, a minor league rehab assignment could begin as early as June 28, with a potential return to the active roster by July 5–7.
Martin, meanwhile, will continue to be evaluated based on performance and matchup needs. His ability to stay in the zone and induce ground balls could earn him extended looks, especially if the Cubs continue to navigate a congested relief schedule.
As the season progresses, the Cubs’ ability to balance short-term fixes with long-term roster construction will be tested. For now, the addition of Corbin Martin represents a measured, data-informed response to an immediate need — one that reflects the organization’s commitment to pitching depth and player health.
