Dave Winfield and Don Baylor each drove in two runs and Joe Cowley and Dave Righetti pitched a nine-hitter yesterday to lead the New York Yankees to a 7-3 victory over the Red Sox in Boston.

The Yankees, who have won five straight, trail first-place Toronto by seven games in the AL East. Boston has lost six of eight.

Cowley (10-5) allowed eight hits and one walk while striking out six in seven innings. Righetti earned his 21st save.

Afterward, Righetti, who pitched for the third consecutive game, talked about leaving the bullpen: "(Yankees Manager) Billy Martin all along wanted me to be a starter, I wanted to be a starter and I think (owner) George Steinbrenner wanted me to be a starter, but someone was needed to fill some shoes in the bullpen. Now I would like to think that someone would have to fill my shoes. It looks as if that maybe they can move me back next year."

New York took a 3-0 lead in the first off loser Dennis (Oil Can) Boyd (11-10). Rickey Henderson walked and Don Mattingly singled. Winfield followed with a ground ball down the left field line that caromed off the edge of the stands for a double, scoring both runners. Winfield moved to third on Ken Griffey's fly ball and scored on Baylor's sacrifice fly.

The Yankees increased their lead to 4-0 in the second on Henderson's RBI groundout.

Cowley did not allow a hit until Wade Boggs led off the fourth with a single. Boston loaded the bases with none out, but Tony Armas grounded into a double play and first baseman Mattingly robbed Mike Easler of a hit with a diving grab of a grounder.
