A day after clinching a playoff spot, the A's can lock up home-field advantage in the AL Wild Card Game with a win Saturday in Seattle.
Left-hander Brett Anderson will be on the hill for Oakland, making his 31st start of the season to match a career-high. The 31-year-old enters the game with a 12-8 record and 4.00 ERA. The 12 wins are already a career-best.

Seattle counters with fellow southpaw Marco Gonzales. The 27-year-old is 16-12 with a 4.09 ERA in 33 starts this year. The 16 wins are tied for fifth in the AL.
Gonzales has already faced the A's four times this season, going 3-1 with a 4.00 ERA. In eight career appearances against Oakland, he is 4-2 with a 3.88 ERA.
The A's will load their lineup with right-handed hitters against the left-handed Gonzales. First baseman Matt Olson is the only lefty in the lineup, batting fourth. Chad Pinder will start in left field again, despite taking a scary spill late in Friday's game. He will hit seventh.
Here are the full lineups for the A's-Mariners game, which will be broadcast on NBC Sports California and the MyTeams app. Coverage begins at 5:30 p.m. PT, with first pitch at 6:10.
