Pittsburgh ? Jason Bay’s two-run single in the sixth inning off Wandy Rodriguez gave the Pittsburgh Pirates a 5-3 victory Thursday over Houston and their second three-game sweep of the Astros this season.

Barely 12 hours after the Astros left 18 runners on base during a 4-3, 16-inning loss to the Pirates, they stranded 13 and played sloppily in the field with two errors during Pittsburgh’s go-ahead sixth inning against Rodriguez (0-3).

Houston pushed across two runs in the ninth but John Grabow got Adam Everett to ground into a forceout at second with the bases loaded to end the game. It was Grabow’s first save since 2004.

Jonah Bayliss (2-1) got the victory by pitching two scoreless innings.

The Pirates scored three runs in the eighth when pinch-hitter Xavier Nady was hit by reliever Chad Qualls’ pitch with the bases loaded and Ryan Doumit, recalled from the minors earlier in the day, added a two-run single.

St. Louis – Skip Schumaker had a career-best three hits and two RBIs to help the Cardinals rally for the win.

Kyle Lohse (1-1) allowed five runs and 11 hits in six innings for Cincinnati, which is 3-7 in its last 10. Brandon Phillips and David Ross homered.

Diamondbacks 7, Padres 4

Phoenix – Tony Clark has his second two-homer game of the season, and Livan Hernandez pitched seven solid innings to lead Arizona past San Diego.

Clark broke a 3-3 tie with shot into the pool area in right-center leading off the fourth. He drove in two more with a towering homer to right in the sixth.

Both home runs came off San Diego starter Chris Young (2-2), who gave up six runs, five earned, in 5 1/3 innings. He walked six, struck out three and had two wild pitches.

Jose Valverde pitched the ninth for his eighth save in nine chances.

Durham doubled home the go-ahead run in the eighth inning after Bonds hit into a double play with runners on the corners, and San Francisco won its eighth straight.
