The Chicago Cubs have bolstered their pitching staff by signing left-handed pitcher Jake Brentz. Brentz, 30, brings significant experience to the bullpen. He made his MLB debut with the Kansas City Royals in 2021, leading the team with 72 appearances and posting a 3.66 ERA over 64 innings. However, his career was interrupted by a Tommy John surgery in 2022, sidelining him for the entire 2023 season.
After his recovery, Brentz joined the Kansas City Monarchs in the American Association in 2025. In 13 appearances, he recorded a 4.38 ERA with 17 strikeouts and one save over 12.1 innings. Notably, he averaged 95.7 mph on his fastball, showcasing the velocity that made him a promising prospect earlier in his career.

The Cubs’ decision to sign Brentz reflects their ongoing efforts to strengthen their bullpen. With his previous MLB experience and recent performance in the American Association, Brentz offers the potential to contribute effectively to the Cubs’ pitching depth. His addition provides the team with a left-handed option capable of facing both left- and right-handed batters.
Brentz’s signing is part of a broader strategy by the Cubs to enhance their pitching staff. The team has also made other moves to improve their bullpen depth, aiming to maintain a competitive edge throughout the season.
As the Cubs continue to evaluate their roster, Brentz’s performance in the coming weeks will be crucial in determining his role within the bullpen. His ability to regain his pre-injury form could make him a valuable asset for the team moving forward.
