Second baseman Marco Scutaro hit a tiebreaking two-run single with two outs in the eighth inning and the Athletics beat the Angels 4-2 on Wednesday.
The A’s evened the season series between the AL West rivals at 6-6. Anaheim swept Oakland in a three-game series April 23-25.
Adam Kennedy hit a game-tying two-run homer in the fifth for the Angels, who lost for the fifth time in seven games.
Anaheim starter John Lackey gave up seven hits and two runs in six innings.
Washburn leads the Angels with an 8-3 record to go with his 4.76 ERA. The left-hander is 1-1 with a 5.40 ERA in five June starts. Washburn has been better of late, allowing only one earned run over the last three starts.
Washburn has a 7-8 record and 3.72 ERA in 21 career appearances against Oakland, including 20 starts.
The A’s have won two straight and five of seven to move with in 1 1/2 games of Texas for first place in the AL West.
Oakland’s bullpen seems to have gained some stability with the addition of closer Octavio Dotel. He worked the ninth inning Wednesday for his second save in three opportunities since being acquired from Houston in a three-team trade last Thursday.
Oakland has converted only 17 of its 30 save opportunities. Dotel now has 16 saves in 20 opportunities with both Houston and the A’s.
Oakland will start youngster Kirk Saarloos against Washburn in the series finale. Saarloos was called up from Triple-A Sacramento last week to bolster the team’s ailing bullpen.
The 25-year-old will make his first start of the year in place of right-hander Rich Harden, who partially dislocated his non-throwing shoulder over the weekend.
Like Dotel, Saarloos was acquired in a trade from Houston back on April 17.
