PHILADELPHIA -- Nationals starter John Lannan was 21 months old when Jamie Moyer picked up his first big league "W."

On Sunday afternoon, the veteran Phillies lefty will try, for the sixth time, to become the 46th member of baseball's 250-win club -- with only Lannan and his Washington teammates standing in the way at Citizens Bank Park.

Moyer has been stuck on 249 victories since April 26, dropping four straight starts.

But while he was knocked around by the Mets and Dodgers, the 46-year-old Moyer looked and felt better in his past two outings. He allowed three runs in six innings during a 5-1 loss to the Reds and four runs in six innings during Monday's 5-3 loss to the Marlins -- considerable improvement, given his 7.42 season ERA.

"I feel like I'm back to where I need to be," Moyer said after Monday's start. "The final result's not there. It's a work in progress."

Over his 23-year career, Moyer is 12-4 with a 2.96 ERA against the Nationals/Expos franchise.

WSH: LHP John Lannan (2-4, 4.11 ERA)
On Monday, Lannan was solid for the first five innings, but a Gary Sheffield home run proved costly, and the Nationals lost to the Mets, 5-2.

After Luis Castillo led off with a double and Carlos Beltran walked, Sheffield came to the plate, swung at the first pitch and hit a three-run homer over the left-field wall.
