Cubs Add Left-Handed Reliever Antoine Kelly to Bolster Pitching Depth

The Chicago Cubs made a quiet but notable addition to their pitching staff on Saturday, acquiring left-handed reliever Antoine Kelly from the Los Angeles Dodgers. The move reflects the organization’s ongoing effort to reinforce its depth as injuries continue to test the pitching staff.

While the deal does not represent a major deadline acquisition, it underscores Chicago’s willingness to remain active in the market for controllable arms. President of baseball operations Jed Hoyer has repeatedly emphasized that the club is not fully focused on the trade deadline, but smaller moves remain part of its approach.

Kelly, 26, arrives as a pitcher still searching for his first major league opportunity. Despite never appearing in the big leagues, he has drawn attention throughout his minor league career for his ability to generate strikeouts at a high rate.

Now joining his fourth organization, Kelly brings both upside and uncertainty as the Cubs look to stabilize a bullpen that has been effective in results but less consistent in underlying metrics.

1. Strikeout Potential Defines Kelly’s Profile

Kelly’s most attractive trait has consistently been his ability to miss bats. At Triple-A Oklahoma City this season, he maintained a strikeout rate of more than one per inning, continuing a trend that has followed him throughout his professional career. That swing-and-miss ability has kept him on the radar of multiple organizations, even as command issues have limited his progression. His high walk rate, recorded at 18.1%, remains one of the key concerns evaluators continue to monitor. Advanced metrics also highlight the volatility in his performance. His expected ERA of 5.16 and expected FIP of 6.38 at Triple-A suggest that while his raw stuff is intriguing, results have not consistently matched the underlying profile. Despite those concerns, teams remain interested in his potential as a low-cost bullpen option, particularly given the premium placed on left-handed relief pitchers with strikeout upside.

2. Journeyman Path Through Multiple Organizations

Kelly’s career has included several stops since entering professional baseball as a second-round pick by the Milwaukee Brewers in the 2019 MLB Draft. He initially developed within Milwaukee’s farm system under then-manager Craig Counsell’s organization. In 2022, he was traded to the Texas Rangers as part of a multi-player deal that included Matt Bush and Mark Mathias. That move marked the beginning of a series of transitions across multiple organizations. Since leaving Milwaukee, Kelly has also spent time with the Colorado Rockies and most recently the Dodgers. With Colorado’s Triple-A affiliate, he logged 34 appearances and posted a 5.63 ERA over the course of the season. Despite flashes of dominance, he has struggled to find consistency, a factor that has kept him from breaking through to a permanent major league role.

3. Cubs Seek Low-Risk Bullpen Reinforcement

For the Cubs, the move represents a depth-focused addition rather than a guaranteed roster upgrade. Chicago’s bullpen has performed respectably in terms of results, but underlying indicators suggest potential regression if injuries continue to mount. The team currently holds a 3.69 ERA from its bullpen group, though advanced metrics such as a 4.51 expected ERA point to areas of concern beneath the surface performance. That gap has made additional depth increasingly valuable. Kelly now enters an organization that may offer a clearer pathway to the majors. With pitching injuries already impacting Chicago’s roster, there is a realistic opportunity for him to contribute sooner rather than later. If he can improve his command while maintaining his strikeout ability, the Cubs could uncover a useful bullpen piece at minimal cost. For now, however, the move represents a calculated depth addition as Chicago continues to navigate the long MLB season.
