Shane Bieber is currently undergoing rehab from Tommy John surgery, which leaves the Cleveland Guardians with a young and inexperienced pitching rotation. Pitching coach Carl Willis, who has a long history of developing pitchers, is tasked with adapting his strategies to their strengths. With new technology and training methods, Willis emphasizes the need for pitchers to develop a complete arsenal of pitches, capable of attacking various zones of the strike zone. The Guardians are also working with new additions like Luis Ortiz and Slade Cecconi, focusing on refining their pitches and maximizing their potential. The team aims to create pitchers who command multiple pitches effectively while ensuring that they remain competitive in games.
