Dave Stapleton drove in four runs with a homer and a single and the Red Sox, with a five-run third inning, defeated the Milwaukee Brewers, 9-3, in Boston last night. It was the Red Sox's seventh victory in eight games.

"You can feel the pennant fever everywhere," Stapleton said.

Right-hander Dennis Eckersley (9-6) settled down after allowing two runs in the third to pitch his eighth complete game this year.

Stapleton, Jim Rice, Jerry Remy, Carl Yastrzemski, Carney Lansford, Tony Perez and Rick Miller each had two hits. Boston got 14 hits off three Milwaukee pitchers.

The Brewers, falling out of a tie with the Red Sox to third place in the AL East, scored twice in the third on a walk, Jim Gantner's double and Robin Yount's single.

However, the Red Sox, 24-16 since the strike ended, came back quickly against Milwaukee starter Moose Haas (9-7).

With one out in the home third, Remy singled and took second on an infield out. Rice doubled, scoring Remy, and, after Yastrzemski walked, Lansford lined an RBI single to right. Stapleton followed with a line shot into the left field screen for his eighth homer.

Boston scored twice in the fourth, once in the fifth and once in the sixth en route to its 10th victory in the last 13 games and 12th in the last 16.
