The Seattle Mariners visit Progressive Field this Saturday looking to tighten their grip on the final AL wild card spot while the Cleveland Guardians desperately need wins to stay within striking distance of October baseball.
Seattle sits 72-62 and holds a crucial three-game cushion over Kansas City for that playoff berth, but Cleveland has clawed back into contention at 66-66 despite a recent six-game skid.
With Logan Gilbert taking the mound for the Mariners against Gavin Williams, who carried a no-hitter into the ninth earlier this month but has struggled since, this matchup could prove pivotal for both clubs' postseason hopes.

Cleveland Guardians vs. Seattle Mariners preview
The Mariners arrive in Cleveland clinging to the final AL Wild Card spot, just three games ahead of Kansas City, while the Guardians find themselves five games back and desperately needing to string together wins in the season's final month.
Logan Gilbert takes the mound for Seattle riding momentum from his dominant 13-strikeout performance against Oakland, though his road struggles this season could be problematic against a Cleveland offense that's managed just 3.85 runs per game.
Gavin Williams has been maddeningly inconsistent for the Guardians, carrying a no-hitter deep against the Mets three weeks ago before failing to escape the fourth inning in two of his last three starts.
Seattle's offense has been more productive away from T-Mobile Park this year, averaging nearly five runs per game on the road, which could be crucial against a Cleveland pitching staff that's allowed 4.32 runs per nine innings.
The Guardians desperately need their home ballpark to provide an advantage, sitting at .500 overall while watching their playoff hopes slip away with each passing series.
With both teams fighting different battles in the playoff race, this middle game of the series could prove pivotal for Seattle's wild card positioning and Cleveland's fading postseason dreams.
