PHILADELPHIA -- Saturday's game between the Phillies and Nationals, originally scheduled to begin at 7:05 p.m. ET, has been pushed up to 3:55 p.m. and will be broadcast on FOX.

Depending on how the next few days unfold, Saturday's game could be a big one for Philadelphia, which currently holds a 2 1/2-game lead over the New York Mets with five to play.

The Phils will likely turn to their veteran left-hander, Jamie Moyer, on Saturday. The 45-year-old leads the team in wins and has been Philadelphia's most consistent starting pitcher in 2008.
