Key Storylines
Pitching Matchup
- Mariners: Bryan Woo (10–7, 3.02 ERA) Woo has been a reliable force in Seattle’s rotation and he was an All-Star this year. His consistency and ability to limit runs will make him tough for the A’s to overcome in this contest.
- Athletics: Luis Morales (1–0, 1.86 ERA) Morales has only pitched 9.2 innings this year. He has impressed with a 1.86 ERA and a 1–0 record over that small sample size. Facing a potent Mariners lineup will be a significant test for him.
Key Players
- Mariners: Julio Rodríguez continues to be a key offensive contributor for Seattle. He brings both power and speed to the Mariners’ lineup.
- Athletics: Brent Rooker has been a bright spot for the Athletics and will need to do his part for the A’s to help figure out Woo.
