Dave Winfield drove in four runs with a homer and single and Ken Griffey saved the victory with a sensational catch as the Yankees won their fifth straight, beating the Boston Red Sox, 6-5, yesterday in New York. The victory, coupled with Toronto's 5-3 loss in Cleveland, closed the Yankees within four games of the Blue Jays in the East.

Winfield, who gave the Yankees a 2-0 lead with his first-inning homer off Bruce Hurst, singled home two runs in the seventh to tie the score, 5-5, then scored on Don Baylor's double.

With one out in the top of the ninth, Marty Barrett hit a fly ball off Bob Shirley that almost tied the game. But Griffey, who entered the game as a pinch hitter in the seventh, climbed the eight-foot-high wall with his right foot, balanced atop the fence with his left arm and reached several feet over the wall to make the catch. As he came down, he stumbled and turned a somersault but held the ball.

Rich Bordi came on to strike out pinch hitter Tony Armas.

"Really, I'm just stunned by the whole thing," Griffey said. "I didn't do any planning or thinking, I just reacted. The ball came down and hit in my glove and then bounced and I had to recatch it. I was glad I was stuck in the wall."

New York's Don Mattingly extended his hitting streak to 17 games with a double.
