The Washington Nationals have completely collapsed, and they now sit 9.5 games back of New York in the NL East. After losing 2-of-3 in Miami, they begin a new series tonight in Philadelphia. The Phillies are coming off back-to-back home wins over the Cubs, and with a hot young pitcher on the mound tonight, we could see a pitcher's duel here in Philly.

Here are my keys to the game:

1. Pitching - The Phillies hand the ball to Aaron Nola, who has impressed in his first 10 major league starts. Nola (6-2, 3.56 ERA) blanked the Braves through seven innings, fanning seven in a 5-0 home win over Atlanta in his last outing. He's 3-1 with a 2.10 ERA in five starts at Citizen's Bank Park. The Nationals counter with Jordan Zimmerman, who is 10-5 with a 2.80 ERA in 22 starts under the lights this year.

2. Bryce Harper - The National League MVP candidate suffered an injury that forced him to leave last night's game, and his status remains uncertain for tonight's game. He's been struggling, just 4-for-20 in his last six games.

3. X-Factor - Zimmerman is 4-2 with a 2.63 ERA in his last six starts versus Philly.


Selection: This is a play on the Nationals@Phillies to go UNDER the total (10*)
