Featured Matchup: Mariners vs. Athletics

The Seattle Mariners travel to Sutter Health Park to face the Athletics on Saturday, September 12, 2026, at 9:40 PM ET. Both American League West clubs enter this late-season matchup looking to finish their 2026 campaigns on a high note.

Seattle hands the ball to right-hander Bryan Woo (11-9), while the Athletics counter with left-hander Gage Jump (6-10). Woo has provided steady rotation depth for the Mariners throughout 2026, displaying consistent command and keeping opponents under control. On the other side, Jump has shown high strikeout upside in his rookie campaign, though pitch counts and long-ball vulnerability have impacted his overall record.

The offensive matchup highlights contrasting team styles. Seattle relies heavily on middle-of-the-order production from Julio Rodríguez and Randy Arozarena, while the Athletics rely on explosive power outbursts, featured prominently when they hit four home runs in a single inning against Seattle earlier this season.
