ANAHEIM Pinch hitter John Jaso had a go-ahead, three-run homer in the seventh inning, and the A's blew a four-run lead before rallying to beat the Los Angeles Angels 9-5 Tuesday night in the majors' final home opener.
Brandon Moss had three hits and four RBIs, delivering an early two-run single before adding a two-run homer after Jaso's shot. Coco Crisp also hit his fourth homer for the A's (6-2), who have won six in a row.
Josh Hamilton went 0 for 4 with a sacrifice fly in his home debut for the big-budget Angels, who dropped to 2-5.
Howie Kendrick had three hits and capped Los Angeles' three-run rally in the sixth with a tiebreaking triple off Ryan Cook (1-0).
After the A's put two runners on in the seventh against Kevin Jepsen (0-1), Jaso's two-out drive landed on top of the chest-high fence in right field, skipping into the seats for his first home run.
Two batters later, Jepsen yielded Moss' first home run.
Albert Pujols reached base four times for the Angels, whose first homestand already was off to a rocky beginning before C.J. Wilson's mediocre start and the bullpen's struggles: Staff ace Jered Weaver was ruled out for at least a month with a broken left (non-throwing) elbow Tuesday morning.
Hamilton was greeted in right field by fans holding up "Hamiltown" signs for his first game at Angel Stadium since he left the Texas Rangers last winter to sign with their American League West rivals.
The $125 million slugger struck out on three pitches with the bases loaded in his first plate appearance and grounded weakly back to the mound with the bases loaded again in the fourth. But Hamilton also made a diving catch in right field in the fifth inning before tying the score with his sacrifice fly in the sixth.
Note A's second baseman Scott Sizemore left in the fourth inning after spraining his left knee while chasing Mike Trout's short outfield fly. He is returning to the Bay Area today for an MRI.
