PHILADELPHIA -- Roy Oswalt threw seven strong innings and Doug Brocail tossed a flawless ninth in the Astros' 2-1 win over the Phillies on Wednesday. But manager Cecil Cooper couldn't stop gushing over the eighth-inning performance turned in by 23-year-old lefty Wesley Wright.

"He looked like a guy that was a seasoned veteran the way he went about it," Cooper said. "He attacked them and he was confident."

Wright struck out the side -- Pedro Feliz, Chase Utley and Ryan Howard -- on 12 pitches. With the scoreless inning, he lowered his ERA to 2.70. Wright has only allowed one hit and one earned run in six appearances, a span of 3 1/3 innings -- not bad for a 23-year-old Rule 5 Draftee who recently completed his first Spring Training as a Major Leaguer.

"It's been exciting for me," Wright said. "I'm having a lot of fun. When you get guys out, it's more fun. It's been a great experience all the way through from Spring Training until now."

Wright impressed the club in Spring Training and hasn't slowed down since, stabilizing the back end of the bullpen. To whiff Feliz, Utley and Howard in a key inning was even more pleasing.

"He just showed me a lot of confidence," Cooper said. "He showed me he believes in himself. He attacked the hitters, and I think that's what we talked about in Spring Training -- to try and command his fastball and get ahead of the hitters. Bang, bang, bang, that's what he did."
