The Sacramento Athletics host the Seattle Mariners at Sutter Health Park on Saturday, September 12, 2026, with first pitch set for 9:40 PM ET. Gage Jump gets the ball for the A's against Seattle's Bryan Woo in a late-season regular season matchup that carries real weight for both clubs. The game airs locally on NBCSCA and Talk 650 KSTE, with Spanish-language coverage on KVMX 92.1/105.5.

Starting Pitchers: Gage Jump vs. Bryan Woo

Jump draws the start for Sacramento in what shapes up as a pivotal assignment. Specific season numbers for Jump are not available heading into the start, so the focus falls on what he does on the mound Saturday night — plain and simple. The left-hander will need to keep a Seattle lineup at bay long enough to give the A's bullpen a manageable situation late.

On the other side, Bryan Woo toes the rubber for the Mariners. Woo has established himself as a legitimate rotation piece in Seattle, and Sacramento's lineup will have to work counts and manufacture offense to get to him. No current ERA or win-loss figures are confirmed for Woo entering this start, but his presence at the top of the Seattle rotation speaks for itself.

Keys to Watch at Sutter Health Park

Lawrence Butler and Shea Langeliers Must Produce

With Butler slotted third and Langeliers anchoring the cleanup spot, the middle of this order carries the offensive load. If those two can get on track against Woo, the A's have enough depth around them to string something together. A quiet night from that duo makes life very difficult.

Jump's Command in the Early Innings

Getting through the Seattle lineup cleanly in the first two or three innings sets the tone for everything that follows. If Jump commands the zone and avoids early traffic, Sacramento controls the game. If he struggles, the bullpen faces a long, grinding night at Sutter Health Park.

Zack Gelof's Presence in the Six Hole

Gelof batting sixth gives this lineup a genuine threat deeper in the order. Woo cannot coast through the bottom third without respecting that bat. Gelof producing in that spot keeps pressure on Seattle's pitcher well past the cleanup hitter.

Prediction

This is a tight, low-scoring game that comes down to which starter goes deeper. Woo is a difficult assignment, but Sutter Health Park has been a genuine home for this team, and the lineup has the pieces to scratch out enough runs. Jump needs to give the A's five solid innings. If he does, take Sacramento in a 3-2 decision. If the bullpen is forced in early, this one gets away late.
