Wade Boggs, going over the 200-hit mark for the third consecutive season, was four for four in the second game in leading the Red Sox to a 5-3 victory and a split of a doubleheader with the Baltimore Orioles yesterday in Boston.

In the first game, Eddie Murray, Mike Young and John Shelby hit eighth-inning homers as the Orioles broke a 1-1 tie with six runs, then held on for a 7-5 victory. Boggs had a single and double, his 199th and 200th hit this season, in the first game.

In the second game, Dennis (Oil Can) Boyd had a shutout going into the ninth for Boston when Murray and Young hit consecutive doubles and Larry Sheets hit his 16th homer. Steve Crawford got the last out for his ninth save.

Dwight Evans led off the Boston first with his 22nd homer and Jim Rice drove in two runs with a single and sacrifice fly as the Red Sox got their eighth victory in 10 games.

Boyd (13-11) who ended a nine-game winless streak with a victory over Cleveland last Thursday, didn't allow a runner beyond second base until the ninth. He struck out seven and walked two.

Boggs raised his league-leading average to .368 with four singles in the second game. He also walked.

With two out in the fifth, he singled, went to third on a single by Bill Buckner and scored on Rice's single.

Singles by Marc Sullivan and Evans and the walk to Boggs set up Rice's sacrifice fly in the seventh.

"Two hundred hits is not something I shot at for the year," Boggs said after his fifth four-hit game of the season gave him 204 hits, with 23 games left. "It's very gratifying, but it's not something I think of at the start of the year."

Baltimore right-hander Mike Boddicker (12-15) was the loser in the second game.

In the opener, Storm Davis (10-7) allowed nine hits and struck out six without allowing a walk in seven innings, outpitching Bruce Hurst (10-11). Don Aase pitched 1 2/3 innings for his ninth save.

After Young tied the score at 1-1 with his 25th homer in the sixth, Cal Ripken began the Orioles' eighth with a double, extending a career-equaling hitting streak to 16 games.

Murray then broke a zero-for-16 slump against Hurst and a zero-for-12 against Boston this season with his 27th homer.

Young followed with a homer into the bleachers in center, knocking out Hurst, who allowed eight hits, struck out six and walked five.
