Tom Brunansky's bases-loaded single scored Kent Hrbek from third with one out in the bottom of the 10th inning today to lift the Minnesota Twins to a 6-5 victory over the Toronto Blue Jays.

The loss dropped first-place Toronto's lead over the idle New York Yankees to 4 1/2 games in the AL East.

Hrbek led off the inning with a single off loser Tom Henke (3-1). One out later, Randy Bush singled to put runners on first and third. Henke then intentionally walked Mark Salas, and Brunansky singled to center off reliever Jim Acker.

Brunansky's RBI was his first since Aug. 16 and broke a one-for-18 batting slump. "Something's bound to go right," he said.

Pete Filson (4-5) pitched two innings and allowed just one hit to earn the victory.

Salas' two-run eighth-inning home run off reliever Henke tied the score, 5-5. The Twins had scored an earlier run in the inning on a sacrfice fly.

Toronto had broken a 2-2 tie with three runs in the seventh. Willie Upshaw tripled and scored on Ernie Whitt's single. After two walks and a force out, Lloyd Moseby singled to right and two runs scored when Brunansky bobbled the ball.

Twins Manager Ray Miller was ejected on the force play when he argued that Damaso Garcia had run out of the base line, which would have effected a double play.
