SEATTLE -- Vladimir Guerrero hit two home runs -- including a two-run shot in the ninth inning -- and the Los Angeles Angels moved closer to securing home field throughout the playoffs with a 6-4 victory over the Seattle Mariners on Thursday night.

Mark Teixeira had a one-out single off J.J. Putz (6-5) in the ninth. Guerrero then hits the first pitch from Putz into the bullpen in left for his 27th home run and his 36th multihomer game.

With the victory, Los Angeles (99-60) closed in on the best record in the American League and home-field advantage. Tampa Bay (96-63), which lost to Detroit 7-5 on Thursday, is three games back with three to play.

The Angels matched the franchise record for wins in a season, set by the 2002 team that won the World Series, and extended the franchise record for road wins with 50.

Jose Arredondo (10-2), who allowed a tying two-run homer to Yuniesky Betancourt in the seventh, was the winner.

Scot Shields finished the ninth to pick up his fourth save.
