HOUSTON (AP) _ Moises Alou hit a two-run single in the fifth inning and a solo homer in the seventh for his first RBIs since the 1998 season, leading the Houston Astros to an 8-5 victory over the Philadelphia Phillies on Saturday.

Alou, who missed all of last season recovering from knee surgery, put the Astros ahead to stay 6-4 with his single off Kirk Bullinger. His first homer since Aug. 24, 1998, made it 8-5.

Ken Caminiti hit a two-run homer off Chris Brock (0-1) in the third inning to put Houston up 4-2 and added a sacrifice fly in the seventh.

Consecutive RBI doubles by Tomas Perez and Brock tied it again at 4-4 in the fourth inning. It was Brock's first career extra-base hit.

Brock walked the bases loaded in the fifth before Alou lined a single to left off Bullinger to score Craig Biggio and Roger Cedeno. Brock gave up six runs and six hits in 4 1-3 innings.

Mike Maddux (1-0) allowed one run in one inning to get the win. Billy Wagner pitched the ninth for his second save.

It took only two pitches for the Phillies to get the early lead off Dwight Gooden, trying to hold down the Astros' No. 5 starting position. Doug Glanville led off the game with a 404-foot homer over the left-field fence.

The Astros regained a 2-1 lead in the second inning on Tim Bogar's two-run triple. Former Astros outfield Bobby Abreu's RBI single tied it in the third.

Gooden allowed four runs and six hits in four innings.

Notes: Cedeno was 0-for-11 before his seventh inning triple. ... Brock was 6-8 with the Phillies last season but his season ended July 23 with a knee injury. ... Jeff Bagwell has averaged a home run in every 18 at bats in his career. He has gone 51 at-bats since his last homer Sept. 19 at St. Louis.
