Cubs Reliever Brad Keller Steps into Closer Role, Showcasing Enhanced Velocity and Pitch Mix

Chicago Cubs right-hander Brad Keller has emerged as the team's closer following Daniel Palencia's shoulder injury, presenting a significant opportunity for the former starter. Keller has been exceptional in a full-time bullpen role this season, boasting a 2.17 ERA and 0.96 WHIP, with no earned runs allowed since the All-Star break. His transition to relief has notably increased his fastball velocity to over 97 mph, up from his career average of 93-95 mph, and improved its vertical break. Additionally, his changeup is now harder with more arm-side run, achieving a 43.1% whiff rate against lefties. His sweeper, a pitch only introduced in 2023, has become a dominant offering against right-handed batters, with a 49.1% whiff rate and 86 mph velocity.
