Tonight's lineup: Martinez in center; Howard sits

Two days after trading Shane Victorino and Hunter Pence, the basement-dwelling Phillies are prepping for a sweep of the division-leading Nationals.

Cole Hamels opposes lefty Ross Detwiler in the final meeting of a three-game set.

Ryan Howard has been given the night off, with Ty Wigginton filling in at first.

Nate Schierholtz, who played his first game as a Phillie Wednesday night, has been replaced in right field by John Mayberry, as the two begin their predicted lefty-righty platoon. Dom Brown shifts to left while call-up Michael Martinez, who has traditional played the infield for the Phils, gets the start in center.

Carlos Ruiz returns to the lineup and will back cleanup.

Here's how they'll face Detwiler in order:

1. Jimmy Rollins, SS
2. Kevin Frandsen, 3B
3. Chase Utley, 2B
4. Carlos Ruiz, C
5. Ty Wigginton, 1B
6. John Mayberry, Jr., RF
7. Domonic Brown, LF
8. Michael Martinez, CF
9. Cole Hamels, P
