OAKLAND — Jose Bautista hit a go-ahead double in the top of the 10th inning, and the Toronto Blue Jays beat the A's 5-2 on Wednesday for a series win.
Bautista lined a double to right against Jesse Chavez (2-3). Rookie catcher Stephen Vogt's second costly passed ball of the game allowed Jose Reyes to advance after a leadoff infield single, and Reyes scored on Bautista's hit.
Casey Janssen (4-0) pitched a 1-2-3 ninth for the win, while Brett Cecil finished for his first major-league save in two opportunities.
Colby Rasmus added a two-run single off Jerry Blevins for insurance in the 10th.
A's starter Bartolo Colon and Toronto knuckleballer R.A. Dickey each settled for no-decisions, leaving after six innings apiece with the game tied at 2-2.
A's All-Star closer Grant Balfour struck out the side in order in the ninth, but Chavez couldn't hold down the heart of Toronto's batting order.
Oakland lost for the first time in nine games with Vogt starting behind the plate. His passed ball in the fourth allowed a run to score.
The A's missed plenty of chances in losing for only the fourth time in 11 games — and the fourth in 11 extra-inning contests this year.
Dickey wasn't helped by four errors, two of which allowed the A's to score, and the knuckleballer did not yield an earned run.
Colon, a 14-game winner and All-Star at age 40, allowed seven hits and two runs — one earned — struck out one and walked three.
The AL West-leading A's lost consecutive games for the first time since opening the second half by dropping two in a row in Anaheim.
A's right fielder Josh Reddick was a late lineup scratch after he showed up at the ballpark with a headache, a day after teammate Jed Lowrie's knee hit him in the head after both chased a foul ball along the right field line.
Manager Bob Melvin said it wasn't considered to be a concussion but the team would be cautious and give him until Friday's series opener with the Texas Rangers after an off day today.
