Athletics 10, Angels 4: Bartolo Colon allowed one run in seven innings to win his third straight start and host Oakland swatted four home runs to snap a three-game losing streak.

Derek Norris hit a two-run homer and Jonny Gomes, Adam Rosales and Josh Reddick added solo shots as the Athletics moved a half-game ahead of Los Angeles in the American League West and into a tie with Baltimore for the second wild card spot.

Colon (9-8) retired 16 of 17 batters at one point and stretched his scoreless streak to a career-high 22 1/3 innings before allowing an unearned run with two outs in the seventh.

Angels rookie sensation Mike Trout clubbed his 20th homer in the eighth, becoming the fifth player since 1918 to go deep on his 21st birthday. He also became the youngest player in league history to have 20 homers and 20 stolen bases in a season. Erick Aybar added a two-run blast in the ninth.

C.J. Wilson (9-8) lost his fourth straight decision, surrendering six runs on nine hits in five innings to remain winless in his last eight starts.

A two-run error by Angels third baseman Alberto Callaspo led to a four-run third inning for Oakland, which turned it into a laugher when Norris and Rosales smacked back-to-back homers in the sixth for a 9-0 lead.
