Pitching Matchup
Seattle Mariners – George Kirby
Kirby is 6-7 with a 3.94 ERA and 1.33 WHIP over 96.0 innings this season. The right-hander has allowed 105 hits while striking out 84 batters and walking only 23. Kirby has consistently worked deep into games and gives Seattle another dependable start.
Cleveland Guardians – Gavin Williams
Williams is 9-4 with a 3.82 ERA and 1.14 WHIP across 96.2 innings. The right-hander has surrendered 79 hits while striking out 111 batters with 31 walks. Williams has been Cleveland's most reliable starter and gives the Guardians an opportunity to even the series.
Seattle Mariners vs. Cleveland Guardians Prediction
Cleveland has a slight edge because of the stronger starting pitching matchup and home-field advantage. Williams has been one of the American League's most consistent starters, and the Guardians continue to rank near the top of MLB in team ERA despite recent offensive struggles. Seattle's pitching should keep this game close, but Cleveland is in a good position to respond after Friday's loss and salvage a split heading into the finale.
