HOUSTON (Ticker) -- Ken Caminiti and Moises Alou each homered and knocked in three runs as the Houston Astros earned their first win at Enron Field, an 8-5 victory over the Philadelphia Phillies.

Caminiti and Alou both entered the contest without an RBI this season. But Caminiti belted a mammoth two-run homer into the upper deck in right field in the third inning and Alou added a solo shot in the seventh.

Tim Bogar stroked a two-run triple for the Astros, who opened Enron Field on Friday with a 4-1 loss to the Phillies. Houston played the last 35 seasons in the Astrodome before moving into its new ballpark this season.

Reliever Mike Maddux (1-0) allowed one run in one inning to get the win against one of his former teams. Four relievers gave up one run in four innings before Billy Wagner worked a perfect ninth for his second save.

Dwight Gooden had an unspectacular debut for the Astros, allowing four runs and six hits in four innings. The veteran righthander walked three and struck out one.

"It was weird. I was totally out of sync," said Gooden, who made his major league debut in 1984 in Houston. "I felt good in the bullpen when I was warming up. I just wasn't throwing strikes."

Phillies starter Chris Brock (0-1) lost his debut for his new team as he was tagged for six runs, six hits and three walks in 4 1/3 innings.

Alou came up with the key hit in the fifth, lining a one-out single off Kirk Bullinger into left field that scored a pair of runs that snapped a 4-4 tie.

"That's the matchup I wanted," Phillies manager Terry Francona said. "He can hit anybody high but you can get him out if you pitch him down. Bullinger usually keeps the ball low but that's a tough situation to bring anybody into."

"I felt pretty good and it felt pretty good to win a ballgame like this," said Alou, who missed all of last season with a knee injury. "I was feeling good and like to be in that situation. I came through today."

Philadelphia had a chance to tie it in the next frame but ran into some bad luck. Mickey Morandini was hit by a pitch to start the inning and Tom Prince singled, sending Morandini to third. Tomas Perez followed with an RBI single but Jose Cabrera got out of the inning.

Houston gave itself the final margin in the seventh. Caminiti lofted a sacrifice fly and Alou belted a two-out homer over the left-field wall.

Gooden got a rude welcome back to the National League in the first inning when Glanville sent his second pitch over the left-field wall.

Brock ran into his first trouble in the second. Richard Hidalgo singled with one out and Mitch Meluskey singled to put runners at the corners. Bogar followed with his triple in the right-center field gap.

Bobby Abreu knotted the score in the third with an RBI single before Caminiti belted a 436-foot homer into the right-field seats, giving the Astros a 4-2 advantage.

"Every field in this league (stinks)," Brock said. "That's why you have five or six guys that hit 50 homers every year. I might get 10 if I had 500 at-bats. That's good if that's what the fans want."

Perez and Brock each had RBI doubles in the fourth to bring Philadelphia even again.
