Houston pitcher J. R. Richard had reason to be pleased after pushing his season strikeout total - already a National League record for right-handers - to 303.
"I'm pretty well satisfied. I'm not totally content," Richard, 18-11, said after whiffing six in five innings as the Astros completed a three-game sweep with a 4-3 victory over the Atlanta Braves.
The victory clinched at least a tie for fifth place for the Astros, who took a three-game lead over the last-place Braves in the National League West with three games to play.
Braves Manager Bobby Cox said, "It's disappointing to be in that position. But when you look at our club this same time last year and look at it again this year, you have to be enthused about the future."
Richards, a tall fast-baller, socked his first homer of the season in the third inning, breaking up a scoreless battle with Atlanta rookie Larry McWilliams (9-3).
In the same inning, Terry Puhl walked and raced to third on Jeff Leonard's single, before Bob Watson's ground ball started a merry-go-round of Atlanta errors.
Third baseman Rod Gilbreath fielded the bouncer but his throw to second pulled Glenn Hubbard off the bag, allowing Leonard to siide in safely and Puhl to cross the plate. Hubbard's relay flew past first base for the second error on the play, but Leonard, trying to score all the way from first, was tagged out at the plate.
Atlanta broke a 32-inning drought against Houston pitching when Eddie Miller was hit by a pitch, stole second and continued to third when catcher Bruce Bochte's throw went into center field. Miller scored on an infield out by Bob Beall.
Pinch-hitter Reggie Baldwin doubled in Jose Cruz for another Astro run in the seventh, then scored himself on Raphael Landestoy's double.
Rowland Office singled home two runs in the eighth and chased Astro reliever Rick Williams. Ken Forsch finished the game and recorded his seventh save.
