RESULTS

* St. Louis 4, at Houston 2: Adam Wainwright, a converted closer making his first start, gave up five hits in seven innings and came through with a run-scoring double as the Cardinals avoided their first 0-4 start since 1997 and ended a five-game losing streak to the Astros. Wainwright filled in for ace Chris Carpenter, who sat out because of inflammation in his right elbow.

* Arizona 7, at Washington 1: Rookie Micah Owings shut out the Nationals for five innings on one hit and struck out six, including Ryan Zimmerman on three pitches with the bases loaded in the fifth.

* New York 11, at Atlanta 1: Oliver Perez gave up only five hits and did not walk a batter in seven innings. The Mets have an 0.75 earned-run average, and their starters have all four of their wins this season. They won their first four games, including three against St. Louis, by a combined total of 31-3.

* Chicago 9, at Milwaukee 3: Rich Hill retired the first 15 batters and yielded one hit in seven innings. He got all the run support he needed before he stepped on the mound. The Cubs scored six times in the first inning, capped by Mark DeRosa’s two-run homer.

* Philadelphia 8, at Florida 2: The Phillies were swept at home by Atlanta to start the season, scoring only nine runs in the series. They nearly matched that total in spoiling the Marlins’ home opener.

* at Cincinnati 6, Pittsburgh 1: Jeff Conine hit a three-run homer in the third inning to give the Reds a 4-1 lead.

* Colorado 4, at San Diego 3: Matt Holliday’s two-run homer helped the Rockies ruin the Padres’ home opener.

* Dodgers 2, at San Francisco 1: Brad Penny pitched shutout ball into the eighth inning in the Dodgers’ sixth straight victory in San Francisco.
