Walters (1-0) struck out one in a perfect inning to earn the victory in Monday's 4-3 win over the Twins.
Walters has given up just one unearned run and posted a 2:1 K:BB over his first three innings in the majors. The 23-year-old surged through the Guardians' minor-league system after being selected 62nd overall in the 2023 First-Year Player Draft, logging just 50.1 innings in the minors. He's in the majors for bullpen depth currently, though this will also serve as a first audition for him to potentially be a part of Cleveland's relief corps in 2025.
