Cleveland Guardians vs. Seattle Mariners preview
The Mariners roll into Cleveland sitting six games above .500 and looking to keep pace in what's been a competitive American League wild card race, while the Guardians find themselves at the .500 mark desperately needing wins down the stretch.
Seattle's offense has been middling at best this season, ranking 11th in runs per game at 4.6, but they've gotten solid production from their pitching staff with a 3.97 ERA that's kept them in most games.
George Kirby takes the mound for Seattle with a respectable 3.53 career ERA and strong command, having walked just 90 batters while striking out 581 in his professional career.
The Guardians counter with Logan Allen, who's struggled with consistency throughout his career and brings a concerning 4.55 ERA and 1.464 WHIP into this crucial home start.
Cleveland's offense has been one of the league's worst this season, managing just 3.85 runs per game and ranking 28th in baseball, which puts enormous pressure on their pitching to keep games close.
With both teams' bullpens showing decent save percentages but some vulnerability in high-leverage spots, this shapes up as a game where the starting pitchers could determine the outcome early.
