PHILADELPHIA — A new stadium may not be the only change for the Washington Nationals. They've got a new attitude — a winning one.

Tim Redding took a one-hitter into the eighth inning and Ryan Zimmerman hit a solo homer to help the Nationals stay unbeaten with a 1-0 victory over the Philadelphia Phillies last night.

"Nobody likes to lose. We're tired of it," Zimmerman said.

Redding allowed just a single by Pedro Feliz in the second inning and walked three in seven innings. He outpitched Cole Hamels, who gave up one run and five hits in eight innings.

Redding retired 14 straight batters after Feliz grounded a single to center. He walked Ryan Howard in the seventh and left after walking Geoff Jenkins to start the bottom of the eighth.

Luis Ayala came in and retired the next three batters. Jon Rauch pitched a perfect ninth for his first save in two tries. Rauch got the win in the opener, after blowing a save while filling in for ailing closer Chad Cordero.

The Nationals are 3-0 for the first time since 2003, when they were the Montreal Expos. No team based in Washington has started 3-0 since the American League's Nationals opened 4-0 in 1951.

The Nationals haven't had a winning season since they moved to Washington in 2005.

"We believe," Redding said. "We believe we can compete and play with anybody in the league, whether it's Philadelphia, New York, Atlanta or Florida."
