Sean Gallagher allowed two hits over seven innings in his Oakland debut and fellow newcomer Mike Murton drove in two runs as the Athletics beat the Los Angeles Angels 9-2 on Friday might.

Both players were acquired by Oakland earlier in the week as part of a six-player trade that sent pitchers Rich Harden and Chad Gaudin to the Chicago Cubs.

Jack Hannahan homered and drove in three runs for the A's, who sent 11 batters to the plate in the third and seven in the fourth to break the game open after Los Angeles had taken a 2-0 lead.

Gallagher, who went 3-4 in 10 starts with the Cubs, gave up two runs in the third. He didn't allow a runner past first over his final four innings and retired 14 of the final 16 batters he faced.

Gallagher had seven strikeouts, one shy of his career high, and walked three.

Jon Garland (8-6) lasted 2 2-3 innings and gave up 10 hits and seven earned runs in his shortest outing since going the same distance against Seattle on Aug. 19, 2007. Three of Garland's six losses are to the A's, who are 11-4 lifetime against the right-hander.

Andrew Brown and Dallas Braden both worked a scoreless inning of relief for Oakland, which pulled within four games of first-place Los Angeles in the AL West. The teams play twice more before the All-Star break.

The nine runs were the most for the A's since they scored a season-high 15 to beat Arizona on June 17. Oakland had scored nine runs total in its previous three games.

Murton, who was originally assigned to Triple-A Sacramento but never reported before being notified he was needed in Oakland, had only one hit in five at-bats but made it count with a two-run single off Gallagher. The left fielder made two running catches near the wall.

Los Angeles entered the game with the best road record in the majors but fell to 3-6 in their last nine games away from home.

Chone Figgins accounted for all of the Angels' scoring when his triple drove in Erick Aybar in the second and he later scored on a sacrifice fly.

Hannahan had three hits in a game for the second time this season. Emil Brown also had three hits for the A's.
