The Phillies will host the Atlanta Braves in a three-game series that could ultimately determine the outcome of the National League East.

For the first time this season, the Braves could make some noise in the NL East. They've trailed the Phillies all season but if they sweep the three-game series in Philly, they will be leading the division.

In tomorrow's game, Roy Halladay will face Brandon Beachy. Cliff Lee goes against Tommy Hanson on Saturday. And the series concludes with Cole Hamels squaring off against Derek Lowe.

So far this season, the Phillies have the best record in major league baseball. They have won 55 games and lost just 33. The Braves, with 53 wins and 36 losses, have the second best record in the National League, and the fourth best record in all of baseball.
