DETROIT -- The Tigers' bullpen let another game slip away.
Vernon Wells' two-out, two-run double capped a four-run seventh inning to lift the Toronto Blue Jays to a 6-4 come-from-behind win over Detroit on Tuesday night.
Adam Lind had three hits, including a home run. He drove in two runs for Toronto, which has won two straight over Detroit to move two games above .500.
Gary Sheffield hit two home runs and Magglio Ordonez also homered for Detroit. The Tigers have lost nine of their last 12 games.
After the Tigers went ahead 4-1 with three in the sixth, the Blue Jays did their damage off relievers Bobby Seay and Joel Zumaya in the seventh.
"We've been losing too many games in the seventh inning and later," said Detroit manager Jim Leyland. "You can't do that."
Seay relieved starter Zach Miner and allowed a single to Lind and a double to John McDonald sandwiched around a strikeout. Joe Inglett brought in a run with a groundout. Zumaya came in and allowed Marco Scutaro's RBI single to make it 4-3. After a walk to Alex Rios, Wells lined a pitch into the left-center gap to bring in Scuttaro and Rios and give Toronto the lead.
"I came in and just didn't get the job done," said Seay. "Gave up a couple of hits."
Leyland said he thinks Zumaya (0-2) might be injured. He faced five batters, and gave up two hits and three walks. He was charged with two runs.
"We're getting him checked out. We're very suspicious he's not right," the Tigers manager said. "He's not right -- I know that for a fact. I don't know if he's hurt -- but he's not right."
Zumaya was being examined after the game.
Lind singled in a run in the ninth.
"This was a real team effort," Blue Jays manager Cito Gaston said. "It was a good win because it was a total team effort. We battled from the start. It something that we haven't done in a long time."
A.J. Burnett (15-9) won his fifth consecutive game. He allowed four runs and eight hits in six innings, walking one and striking out six.
"I made a couple of mistakes, but I was able to make the rest of my pitches," he said.
Brandon League pitched the seventh, Scott Downs the eighth and B.J. Ryan the ninth for his 23rd save in 26 chances.
Lind gave Toronto a 1-0 lead with his two-out solo homer in the second. He drove Miner's 0-1 pitch deep into the right-field stands for his sixth home run, estimated at 425 feet.
"This was a complete team effort. Everybody did well," said Lind. "We got got at-bats, good pitching and key hits."
Sheffield tied it with his first homer, with two out in the second.
"The big thing was that I didn't let that first home run bother me," said Burnett. "It was a good pitch that he hit. If you let things like that get to you, you never get yourself straight."
Ordonez led off the sixth with his 15th home run to give Detroit a 2-1 lead. Sheffield hit his second homer, 12th of the season and 492nd of his career two outs later. Brandon Inge added a RBI double later in the inning.
After a pre-game report said he had been placed on waivers, Sheffield didn't speak to reporters after the game. "Not today," he said when reporters approached his locker. ... Detroit 3B Carlos Guillen left the game after seven innings because of lower left back tightness. "I don't know anything about that situation," Leyland said after the game. ... Lind's home run broke an 0-for-13 slump. ... Downs stretched his scoreless streak to 17 2/3 innings.
