OAKLAND, Calif. (AP) - Josh Donaldson homered with one out in the 12th inning, lifting the Oakland Athletics to a 4-3 victory over the Detroit Tigers for their ninth straight victory Friday night.
Donaldson's opposite-field drive to right off Brayan Villarreal (0-2) was his first career game-ending hit.
And in typical 2012 fashion for the reigning AL West champions, Josh Reddick found Donaldson with a pair of celebratory whipped cream pies - a scene reminiscent of the major league-best 14 walk-off wins the A's had last year.
Ramon Santiago hit a two-out triple in the top of the 12th before Chris Resop (1-0) relieved Jerry Blevins and retired Austin Jackson on a fly to center.
The A's improved to an AL-best 9-2, just the third time in Oakland history the club has opened at least 9-2, also done in 1981 (11-0) and 1990 (9-2).
Only the Atlanta Braves at 9-1 have a better record than Oakland.
