TORONTO -- Five weeks after bottoming out at 15 games below .500, the Oakland Athletics are back at the break-even mark.
The A's have won 10 of 11 to move back to .500 (41-41) for the first time since May 2. Oakland has gone 24-9 since it was 15 games below .500 on May 29.
"That's a tremendous climb, a tremendous climb," Oakland manager Ken Macha said. "I credit those guys out there. They are absolutely going for it every night, fever pitched."
Justin Duchscherer (4-1) worked two innings and earned the victory.
"We have that winning attitude, and it's back," Swisher said. "In the month of May when we were struggling, it was really frustrating. Now, we're back to our old ways and having fun."
Kotsay and Crosby led off the 11th with singles off Miguel Batista (4-1) before Eric Chavez hit a long single off the left-field wall. Kotsay and Crosby didn't advance too far, fearing left fielder Gabe Gross would make the catch.
Hatteberg followed with a single to right that scored two, and two batters later, Swisher hit an RBI double to make it 10-7.
"It seemed like whoever was going to hit last was going to win," Swisher said.
Kotsay, Oakland's center fielder, made a spectacular play in the bottom of the 11th when he faked as if he was going to catch Gross' blooper before letting it drop. He then flipped the ball from his glove to his hand and forced out Russ Adams at second.
"That's one of the best plays I've ever seen," Macha said. "What a play. And clutch. It could have been first and second and nobody out. That's why people who don't see this guy everyday don't appreciate what he does. That won the ball game."
The A's had a chance to close out the win in the bottom of the ninth. But second baseman Marco Scutaro failed to turn a potential game-ending double play when his throw to first sailed into the stands and allowed Adams to score the tying run.
Crosby's first career inside the park homer gave Oakland a 5-3 lead in the sixth. Crosby's ball hit off the center-field wall before deflecting off Vernon Wells, who crashed into the wall and fell to the turf. The ball trickled about 10 feet away, far enough for Crosby to race around the bases for the two-run homer.
"I was definitely out of gas. I was hurting for the next couple of innings," Crosby said.
Toronto's Eric Hinske cut the deficit to 5-4 with an RBI grounder in the bottom half of the sixth. Orlando Hudson homered in the seventh to tie it at 5-all. Hudson grabbed his right hamstring while running toward second base and left the game after hobbling home.
Hudson's homer barely cleared the wall in center, and he was running full speed when he pulled up. The team said he had tightness in his hamstring and will be reevaluated Wednesday.
"I don't think we can evaluate it now," Toronto manager John Gibbons said. "We need to wait for the body to cool off."
Swisher gave Oakland a 6-5 lead with his homer off Vinnie Chulk in the eighth. Kotsay also homered off Chulk in the inning, giving Oakland a 7-5 lead.
Reed Johnson's two-run triple in the second gave Toronto a 2-0 lead. Oakland scored three runs in the fourth on Johnson's solo homer and Crosby's two-run single.
Adams tied it with a sacrifice fly in the fifth before Crosby hit his two-run homer in the sixth.
Oakland starter Dan Haren allowed four runs on eight hits in six innings in a no decision. It was just the second time in his last 10 starts that Haren allowed more than three runs.
- Macha has ordered his players not to show up before 4 p.m. ET for Wednesday's 7 p.m. game. Macha said his team always struggles in the second game of an East Coast trip, so he wants them well rested. There is a $450 fine for an early arrival.
- Terrence Long was the last A's player to hit an inside the park home run, on May 9, 2003, against the New York Yankees.
