The Dodgers built a 5-0 lead by the time the Angels came to bat in the second inning, but Chad Billingsley was unable to hold it. Alberto Callaspo ignited a three-run rally in the second with an RBI double and Trout capped a three-run outburst in the fourth with his seventh blast of the season.

Aybar plated a run with a groundout in the second and added an RBI triple two frames later. Hunter completed the scoring in the sixth with a two-run single that saw Trout, who was running on the pitch, score from first base.

Dan Haren (5-7) benefited from the comeback as he surrendered five runs and nine hits over five innings. The right-hander, who has allowed a total of 14 runs in his last three starts, saw his home ERA balloon to 4.53.

Ernesto Frieri worked around a walk in the ninth for his eighth save in as many chances.

Billingsley (4-6) was even worse than Haren, yielding six runs and 10 hits in five frames. The 27-year-old, who has given up 11 runs in 11 innings over his last two outings, fell to 1-5 lifetime against the Angels.

Released by the Angels earlier this year, Bobby Abreu belted a three-run homer for the Dodgers, who have lost three of four in the season series and fell to 0-4 on their nine-game road trip. Andre Ethier and former Angel Juan Rivera had three hits apiece.
