Mariners vs Guardians Odds, Picks & Betting Preview

MLB

As Major League Baseball heads down the regular season home stretch, several teams remain viable contenders for playoff spots. Two of them will meet on Saturday night when the Cleveland Guardians host the Seattle Mariners.

The Guardians are five games out of the last American League wild card spot. At the beginning of August, Cleveland was in a prime position. However, the Guardians are in their worst stretch of the season, and that has badly damaged their playoff prospects.

On the other hand, if the season were to end today, the Mariners would secure the final American League wild card spot. This week, the Mariners began to emerge from a slump that had put their playoff hopes in danger.
