Athletics 5, Blue Jays 1: Alberto Callaspo atoned for a costly error with a tiebreaking two-run double in the ninth inning as visiting Oakland rallied to take three of four in Toronto.

The Athletics carried a 1-0 lead into the bottom of the eighth, but Callaspo had a Jose Bautista grounder go off his glove with a runner on third to allow the tying run to score. Josh Donaldson led off the ninth with a base hit and pinch hitter Brandon Moss doubled before Callaspo - who had the go-ahead two-run double in Sunday's win - lined a shot into the corner in right off Casey Janssen (4-1).

Stephen Vogt followed with an RBI single and Eric Sogard had a sacrifice fly to cap the four-run ninth and help secure a win for Ryan Cook (5-2), who got the last two outs of the eighth in relief of Dan Straily. Oakland's starter yielded an unearned run and six hits in a career-high 7 1/3 innings as the Athletics remained one game behind first-place Texas in the American League West.

Chris Young slugged a leadoff home run against Blue Jays starter J.A. Happ to give the Athletics a 1-0 lead. Oakland produced only two more hits against Happ, who retired 14 in a row at one point and struck out six in seven innings, his longest start of the season and his second since suffering a skull fracture and sprained knee when he was hit by a line drive in Tampa Bay on May 7.

All seven Toronto hits were singles as the last-place club fell to 6-14 in its last 20 home games.
