Diamondbacks vs Guardians Key Matchups and Game Preview
Cleveland's Underrated Arm
Cleveland holds the edge on the mound with Tanner Bibee, who enters at 4-10 despite a solid 3.89 ERA and 1.18 WHIP over 125 innings. Bibee has struck out 97 batters while allowing just 111 hits, and his record has been hurt more by limited run support than ineffective pitching.
Arizona's Rookie Challenge
Arizona counters with rookie left-hander Mitch Bratt, who is 0-1 with a 6.32 ERA and 1.98 WHIP through 15.2 innings after making only a handful of major league starts. Bratt has surrendered 20 hits and 11 walks already, creating a difficult matchup against a disciplined Cleveland lineup.
