The San Diego Padres never got a man past first base last night against Bob Welch, whose three-hitter gave the Dodgers a 1-0 victory. The teams totaled five runs in the three-game series in Los Angeles.

The Padres' Andy Hawkins allowed seven hits in seven innings, but yielded three in a row in the fourth. Mike Marshall got the important one, which scored Bill Madlock. There were no extra-base hits in the game.

Fernando Valenzuela beat the Padres' Eric Show, 2-1, Monday. Dave Dravecky blanked Orel Hershiser and the Dodgers, 1-0, Tuesday.

*Phillies 5, Reds 3: In Cincinnati, Tom Browning of the Reds held the Phillies to one hit but left cold and tired after eight innings with only a 1-1 tie. Reliever Ted Power lost the game in the 11th.

Glenn Wilson broke the tie with a sacrifice fly to center and another run scored on third baseman Buddy Bell's error. Then John Russell hit a home run that ended up providing the winning margin because Steve Bedrosian (1-0) nearly blew the lead in the bottom of the inning.

Gary Redus, who played for the Reds last season, had the hit off Browning, an RBI single in the third.

*Giants 4, Astros 1: The Giants started all-star re-liever Scott Garrelts, who relieved in all his 74 games last season. He had a two-hitter after five innings and yielded only a run on six hits in his 7 2/3 innings in Houston's Astrodome.

"I was worried before the game throwing out of the windup," he said, "but after the first couple of innings I felt comfortable." Teammates Will Clark and Bob Melvin made him feel even better by doubling runs home.
