Dave Bergman's fourth hit of the game was a three-run homer in the 10th inning that gave the Detroit Tigers a 7-4 victory over the Blue Jays in Toronto last night.

The Tigers scored four runs in the eighth inning to tie the game. They lead the second-place Blue Jays by 9 1/2 games in the East and reduced their magic number for clinching the division title to 13.

"It was just one of those nights," Bergman said. "The funny thing is, I know I'm not a home run hitter."

Mike Laga started the rally with a single to center and Tom Brookens ran for him. Chet Lemon singled, then Bergman hit a 1-2 pitch over the center field wall. Ron Musselman (0-1), the sixth Toronto pitcher and former Alexandria Dukes player, was the victim of Bergman's homer, his seventh, and almost a duplicate of his 10th-inning homer that beat the Blue Jays June 4.

"Bergman's killed us all year," Toronto Manager Bobby Cox said. "We'll try to catch Detroit, starting tomorrow."

Willie Hernandez (9-2) worked the last three innings for the victory.

Toronto's Doyle Alexander had a 4-0 lead and a four-hit shutout into the eighth. Kirk Gibson drove in three of the runs with his 24th homer.

"I wanted to win this game as bad, I think, as I've ever wanted anything," Detroit Manager Sparky Anderson said. "If we hadn't won, I probably wouldn't say that. The time has come to play them -- not watch scoreboards. No more scoreboard watching. Let's get it on."
