HOUSTON (AP) -- Frank Thomas needed only two innings to join the home run parade at Enron Field.

Thomas hit a three-run homer over the short left-field wall to highlight a five-run second inning as the Chicago White Sox beat the Houston Astros 7-4 Friday night in the first interleague game played at the new ballpark.

Houston was 14-6 in interleague play at the Astrodome before moving into its new park this season. The game drew 39,028 to put the Astros over 1 million in attendance this season, the quickest they've reached the mark.

"Actually, the homer was a good pitch," Thomas said. "I didn't know he'd come in like that."

The Astros failed to hit a home run for the first time in 18 games, stopping their franchise record streak. There have been 96 homers in 26 games at Enron, just 22 short of the entire 1999 total in the Astrodome.

For the first time, the retractable roof was moved during a game. The game started with the roof closed, but it was opened before the start of the seventh inning.

"It's kind of small, but it is a good atmosphere," White Sox manager Jerry Manuel said of the ballpark.

The White Sox scored five unearned runs in the second inning off Shane Reynolds (5-2), highlighted by Thomas' homer and helped by rookie shortstop Julio Lugo's fielding error. Lugo also ended the sixth by flying out with the bases loaded.

"It was just one of those days, I missed a play, those kinds of things will happen," Lugo said. "They know I'm capable but I'm going to make errors just like anybody else. It's not the first one I've made and I hope it's not the last."

Jim Parque (5-2) allowed three earned run and five hits in 5 1/3 innings. He retired his first 10 batters before Craig Biggio singled, but Biggio was out trying to stretch it to a double.

Parque wasn't ready to leave the game.

"I wanted to go as long as I could," he said. "I'm not questioning his decision. I'd be more worried if I wanted to come out of the game."

Keith Foulke got the final four outs for his 11th save in 12 opportunities.

Chicago went ahead in the big second, starting with singles by Carlos Lee and Greg Norton, the latter bouncing off Lugo's glove. Two outs later, Ray Durham's grounder got through Lugo into center field for an error that allowed bother runners to score.

"Actually, he (Lugo) had two errors, even though they ruled one a hit (Norton's)," Astros manager Larry Dierker said. "They played a big part in the five-run innings.

"We just didn't hit as well as we could have. And we didn't pitch very well, so you add those three things together, poor hitting, fielding and pitching, and it's pretty hard to win at this level," he said.

Jose Valentin singled and Thomas followed with his 11th home run.

Norton's sacrifice fly made it 6-0 in the third.

Houston chased Parque with a four-run sixth inning that included run-scoring singles by Ken Caminiti and Richard Hidalgo and a two-run single by pinch-hitter Matt Mieske.

Chicago scored its final run on an RBI double by Herbert Perry in the ninth.

Game notes
Thomas needs to score one run to become the sixth active player with 300 home runs, 1,000 runs scored, 1,000 RBI and 1,000 walks. ... Lugo led off for the first time this season. "I led off in the minor leagues most of the time," he said. "I'm comfortable there but I'm just grateful to be in the lineup in any spot. I know I need to get on base."
