Walters has a 2.97 ERA, 1.22 WHIP, 41 strikeouts and six saves in 30.1 innings across 33 appearances for Triple-A Columbus.
A pure reliever who received almost $1 million after the Guardians selected him with the No. 62 overall pick last year, Walters was assigned to Double-A to begin his pro career and dominated to the tune of a 1.35 ERA, 1.05 WHIP, two saves and 38 strikeouts in 20 innings. His strikeout rate dipped from 46.3 percent to 31.8 percent and his walk rate spiked from 9.8 percent to 13.2 percent after the bump to Triple-A, but Walters is still one of the best relief pitching prospects in the game. He should figure prominently into Cleveland's setup mix as the 2025 season unfolds.
