TORONTO -- After striking out in each of his first three at bats, Yoenis Cespedes came to the plate with the bases loaded in the seventh and promptly delivered a big hit.
That's the way things are going right now for the streaking Oakland Athletics.
Cespedes broke open a close game with a three-run single and the Athletics beat the Toronto Blue Jays 7-2 Tuesday night for their season-best sixth win in a row.

"We're on a roll," left-hander Travis Blackley said. "We're enjoying the game and we expect to be able to come up big in certain situations and we're doing it over and over again."
Derek Norris hit a two-run homer and Blackley won his third straight decision as the A's improved to 15-2 in July. Oakland (52-44) is eight games over .500 for the first time since July 12, 2008.
"Just winning in itself is contagious," infielder Jemile Weeks said. "Once you get the belief that you can win, it's easier to come about finding that W."
All seven Oakland runs were scored with two outs.
"That's just perseverance, that's just going out there and being clutch," Weeks said.
Travis Snider and J.P. Arencibia each hit solo homers and Brett Lawrie had three hits for the Blue Jays, whose three-game winning streak came to an end.
Blackley (3-2) allowed one run and five hits in seven innings. The left-hander, who has not lost since June 10 at Arizona, walked one and struck out a career-best eight.
"I felt a bit like a fish out of water early, just didn't have a rhythm," Blackley said. "The cutter was disgustingly bad today, it didn't work at all. Luckily the curveball was just phenomenal today. I was able to throw it for strikes and below the zone for swings. That pretty much changed the game for me today because I really didn't hit many spots with any other pitch."
Evan Scribner worked the eighth and Jim Miller gave up Arencibia's 16th homer in the ninth.
Brett Cecil (2-3) allowed two runs and five hits in six innings and has won just once in his past six starts.
"Brett used his changeup, his curveball and his cutter in to right-handers and had a number of batters off-balance," Blue Jays manager John Farrell said.
Cecil has allowed at least one home run in all seven of his starts this season, and 15 of his past 18 overall.
The Athletics put the game away with a five-run outburst in the seventh. Brandon Hicks doubled and Weeks chased reliever Chad Beck with an RBI triple. J.A. Happ came on immediately gave up an RBI double to Coco Crisp, then walked Jonny Gomes.
After a double steal, Josh Reddick walked to load the bases for Cespedes, who had struck out swinging three times. On Happ's 3-2 pitch, Cespedes snapped an 0 for 8 slump by lining a bases-clearing single to center.
Cespedes has at least one hit in 10 of his past 11 games and has 16 RBI in that span. He's batting .487 (19 for 39) in 10 games since the All-Star break.
"He's a tough kid, he doesn't get down on himself," Athletics manager Bob Melvin said of Cespedes. "I've often said that. He'll get upset with himself and you can see he kind of wears it on his sleeve sometimes but he goes up there with more conviction the next time."
Happ was making his Rogers Centre debut after being acquired in Friday's 10-player trade with Houston but failed to make a good impression on his new fans.
"We were in this game, we were battling and I took us right out of it so it's not a good feeling," Happ said.
Oakland opened the scoring in the second when Brandon Inge reached on a two-out single and Norris hit Cecil's next pitch into the second deck in left, his third homer of the season.
The Blue Jays answered in the third on a leadoff homer by Snider, his second. Snider also connected in Sunday's 15-7 victory at Boston.
