HOUSTON (AP) -- Oh, well, wins in stadium openers aren't essential.

Scott Rolen broke up a scoreless game with a sixth-inning home run, and Enron Field officially opened Friday night with the Philadelphia Phillies beating the Astros 4-1 in Houston's first outdoor home game since 1964.

"It was such a wonderful atmosphere," Astros manager Larry Dierker said. "The most disappointing aspect of the loss was we couldn't get enough going to give our fans a chance to show their presence. We couldn't make those vibrations pay off with a win."

	Octavio Dotel had a three-hitter going until Scott Rolen homered in the seventh.

Ron Gant added a two-run homer off Doug Henry in the eighth for the Phillies, who avoided their first 0-4 start since 1987 before a sellout 41,583 fans.

"If you hit to left-center or right-center, you have to crush the ball," Astros shortstop Tim Bogar said. "We are still in a learning process. I can't say yet if it's good or bad."

With former President George Bush and Texas Gov. George W. Bush looking on, the $248 million, retractable-roof ballpark on the edge of downtown opened with a pregame ceremony that included skydivers and the raising of the NL Central flag, the Astros' third straight.

There were three exhibition games last week against the New York Yankees and Texas, but this was the one that counted.

The roof was open and the temperature was 78 degrees, a stark contrast to the climate-controlled Astrodome, the Astros' old home.

"It took me about 15 seconds to get used to the ballpark; it was electric," Rolen said. "The people were excited about the new ballpark. It was great to be here."

Rolen was the first batter to hit a regular season homer in Enron.

"It's a neat thing," he said. "I remember thinking this afternoon, that maybe I could be the first one."

Octavio Dotel (0-1) allowed only three hits until Rolen led off the seventh with a drive over the left-field scoreboard, his third home run of the season.

Rico Brogna's double chased Dotel, and Mickey Morandini's sacrifice fly off Doug Henry made it 2-0 for the Phillies, who also opened the Astrodome on April 12, 1965.

"It's a great ballpark. We're going to have some great memories here," Jeff Bagwell said. "We're going to hit a lot of home runs. We just didn't do it tonight."

Randy Wolf (1-0) also allowed a leadoff homer in the seventh, a 408-foot drive to left by Richard Hidalgo. Wolf allowed five hits in seven innings, leaving with the 2-1 lead. Wayne Gomes finished with hitless relief for his first save.

Wolf won his first five starts with the Phillies last season after being called up from the minors, then lost eight straight.

"I knew my curve was working well in the bullpen but in the first inning I was behind in the count," Wolf said. "Then, I started getting ahead, and I started using my curve and change and they were both working."

Dotel, obtained with outfielder Roger Cedeno in the December deal that sent Mike Hampton and Derek Bell to the New York Mets, allowed a leadoff single to Doug Glanville, then retired 10 straight before a single by Bobby Abreu.

Dotel allowed two runs and five hits in six innings, struck out five and walked one.
