The Seattle Mariners wrap up their homestand with a Sunday afternoon tilt against the Athletics at T-Mobile Park, first pitch scheduled for 4:10 PM ET on September 6. Bryan Woo takes the ball for Seattle opposite Oakland's Gage Jump in a matchup of two AL West clubs playing out the final stretch of the regular season. With September baseball carrying serious weight in the standings, this is exactly the kind of divisional game the Mariners need to handle at home in front of their own crowd.

Starting Pitching Matchup: Bryan Woo vs. Gage Jump

Bryan Woo is the story on the mound for Seattle. The right-hander has been one of the more intriguing arms in the Mariners' rotation, and Sunday gives him another chance to build on whatever momentum he's carrying into the final weeks of the season. Woo's stuff — particularly his ability to generate weak contact — makes him a legitimate weapon when he's commanding the strike zone.

Gage Jump gets the call for the Athletics. The left-hander is a young arm still carving out his footing at the big-league level, and Seattle's lineup will be looking to make him work deep into counts and get to the Oakland bullpen early if possible.

Seattle Mariners Lineup

• Randy Arozarena, LF
• Dominic Canzone, RF
• Julio Rodríguez, CF
• Cal Raleigh, DH
• J.P. Crawford, SS
• Josh Naylor, 1B
• Weston Wilson, 3B
• Michael Arroyo, 2B
• Jhonny Pereda, C

Athletics Lineup

• Henry Bolte, CF
• Jeff McNeil, 1B
• Zack Gelof, 3B
• Lawrence Butler, RF
• Carlos Cortes, LF
• Max Muncy, DH
• Donovan Walton, 2B
• Alika Williams, SS
• Brian Serven, C

Keys to Watch

• Cal Raleigh in the cleanup spot: Raleigh hitting fourth as the DH puts his power bat in prime position. If Julio Rodríguez gets on base ahead of him, the middle of this order can do real damage against a young starter still finding his footing.
• Julio Rodríguez setting the table: J-Rod batting third means Seattle is leaning on his athleticism and bat speed to ignite the offense. His at-bats against a left-handed starter will be worth watching closely.
• Woo's command in early innings: Woo is at his best when he's throwing strikes and keeping hitters off-balance from pitch one. If he establishes his fastball early, this could be a long afternoon for Oakland's lineup.
• Oakland's middle of the order: Lawrence Butler and Zack Gelof give the A's legitimate threats in the three and four spots. Woo will need to keep them from doing damage with runners on base.

Prediction

This is a game Seattle should win at home. Bryan Woo against a relatively inexperienced Athletics starter at T-Mobile Park is a favorable setup for the Mariners, and the lineup has the firepower — particularly with Raleigh and Rodríguez in the heart of it — to generate enough offense to get the job done. The Athletics aren't pushovers, and Butler and Gelof can make anyone pay for a mistake, but expect Woo to go six-plus innings and the Mariners to close this one out. Mariners 4, Athletics 2.
