HOUSTON(AP) -- Rookie Bud Norris regrouped like a seasoned veteran
after giving up Jimmy Rollins' leadoff homer Sunday.

The 24-year-old right-hander struck out six in six efficient
innings for his first win in a month and Carlos Lee had a
two-run single in the Houston Astros' 4-3 win over the
Philadelphia Phillies.

Norris (4-3) allowed two runs and six hits to snap a personal
three-game losing streak and earn his first victory since Aug.
12 at Florida. He had been hit hard since becoming the first
rookie in Astros history to win his first three starts.

"They let you know where you stand a little bit," Norris said of
his last three outings. "You kind of gather yourself, get back
to the basics, just keep going at it and that's exactly what I
did."

Michael Bourn stole two bases and scored twice for the Astros.
Lance Berkman and Miguel Tejada each drove in a run, and Jose
Valverde pitched a scoreless ninth for his 21st save in 25
chances.

The Astros, out of the NL playoff race, have won seven of their
last eight home games.

"They keep playing all the time, they don't quit," manager Cecil
Cooper said. "They play hard all the time."

Jimmy Rollins, Ben Francisco and Jayson Werth homered for the
Phillies. Cole Hamels (8-9) gave up four runs and eight hits
over six innings to lose for the fourth time in seven starts.

Rollins drove Norris' fourth pitch into the Astros' bullpen for
his fourth leadoff homer of the season and No. 32 for his
career. Norris then struck out two of the next four hitters.

"The first batter of the game is always a question mark," Norris
said. "But I came back and the rest of the game, I pitched
really well."

Hamels extended his scoreless streak to a career-best 21 innings
before the Astros got to him in the third. Bourn singled, stole
second and scored on Berkman's one-out bloop single to right for
the first run allowed by Hamels since Aug. 21.

The Phillies traded Bourn to the Astros in November 2007 as part
of the Brad Lidge deal and are familiar with his abilities in
the leadoff spot.

"With the type of speed he has, I think there's a reason he's
been such a huge threat and a big player for their team," Hamels
said.

The Astros scored three times in the fifth to take a 4-2 lead.
Bourn beat out an infield single, stole second and advanced on
Kaz Matsui's infield single. After Berkman grounded out, Lee
blooped a two-run single to right. Tejada then drove in Lee with
a double down the third-base line.

Once again, Bourn triggered the rally.

"He set the stage for the game," Phillies manager Charlie Manuel
said. "He set up their offense a couple of times there. He can
turn the game around. That's what speed will do for you."

Norris retired eight of the last nine hitters he faced. Cooper
said Norris showed more poise than he had in his previous three
starts.

"He's got the stuff, he just has to learn how to pitch," Cooper
said. "Today, he kept his emotions out of it and just kept
pitching."

The Astros called up Norris on July 29, when he was leading the
Pacific Coast League in ERA and strikeouts. He pitched seven
shutout innings in St. Louis, then beat Milwaukee and Florida
before the losing streak.

Norris quickly found his rhythm against the Phillies and his
confidence grew with every pitch.

"As the game progressed, I got into a groove," he said. "Once I
got the ball rolling a little bit, I felt great. I want to keep
it going for the next couple of starts."

LaTroy Hawkins allowed Werth's leadoff homer in the eighth
before Valverde finished.

NOTES: Bourn leads the NL with 52 stolen bases. ... The Phillies
lead the NL with 94 home runs on the road. ... The Phillies
dropped to 51-15 this season when Rollins scores a run. ...
Cooper said INF Jeff Keppinger will miss a few days with
tightness in his back.
