Darryl Strawberry's three-run homer in the sixth inning put the New York Mets ahead to stay in Atlanta yesterday and their 10-5 victory over the Braves extended their winning streak to 10.

The homer, good for a 7-5 lead, came on a 3-2 pitch from Craig McMurtry (0-1). Wally Backman, who had gotten his fourth single of the game, and Keith Hernandez, who had walked, were on base.

"That was a big one," Strawberry said.

The Mets are within a victory of tying the club record for consecutive victories set in 1969 and tied in 1972. Bruce Berenyi (1-0), second of their four pitchers, threw 1 1/3 innings of hitless relief for his first victory since April 12, 1985.

Braves center fielder Dale Murphy, playing in his 675th straight game, left in the third inning after colliding with a fence. He needed nine stitches to close a cut on the palm side of the hand after he chased down Keith Hernandez's fly ball. He is expected to be out a week.

"The panels of the plexiglass just kind of separated a little bit and it sliced it when it went in," Murphy said. He hasn't missed a game since Sept. 26, 1981. His streak is 14th best in major-league history and best among active players.

Manager Chuck Tanner said Murphy definitely wouldn't play tonight.

"I can still hit with the stitches in," Murphy said.

*Padres 5, Cubs 4: Chicago's Rick Sutcliffe took a four-hitter and 4-1 lead into the ninth inning in San Diego.

Marvell Wynne led off with a single. Tony Gwynn hit into a force, but Steve Garvey's single chased Sutcliffe. Pinch-hitter Jerry Royster greeted Ray Fontenot (1-1) with an RBI single. Terry Kennedy then hit a 2-1 pitch over the right field fence to win for Craig Lefferts (3-0).

The Padres' LaMarr Hoyt made his first start this year and left after the fifth, trailing 2-0.

*Expos 7, Reds 4: In Cincinnati, starter Mario Soto (2-2) became the 11th major leaguer to allow four homers in an inning.

Montreal's Andre Dawson and Hubie Brooks homered consecutively to start the fourth. One out later, Tim Wallach homered. After Al Newman's single, Mike Fitzgerald homered.

*Phillies 12, Astros 4: Mike Schmidt homered with two on and Luis Aguayo with one on, all in the first inning off Nolan Ryan (3-3) in Philadelphia.

The six-run inning enabled Shane Rawley (3-1) to win despite yielding 12 hits in his 6 1/3 innings.

Ryan, who never got through the inning, has allowed Schmidt only five hits in his career. But all were homers.

*Giants 2, Cardinals 0: In San Francisco, Mike LaCoss, starting his first major-league game in two years, pitched three-hit ball for 7 1/3 innings, then Greg Minton saved the victory by retiring the last five batters. Jose Uribe's outstanding plays at shortstop helped. He also drove in a run.

*Dodgers 5, Pirates 4: Pinch hitter Cesar Cedeno tripled home the tying run and scored the winning run on Dave Anderson's single in the sixth inning in Los Angeles.

Winner Orel Hershiser (3-2) worked six innings, allowing five hits and striking out seven.
