The Washington Nationals host the Philadelphia Phillies in the nation's capital tonight, and neither team will be going to the post-season in 2015. The Nats may have more to play for though, with Bryce Harper gunning for a batting title and Jordan Zimmerman looking for his 14th win.

Here are my keys to the game:

1. Pitching - Zimmerman (13-8, 3.49 ERA) gave up a pair of runs on six hits, striking out seven in six innings in a home win over Miami in his last start. He's 8-3 with a 2.50 ERA in 18 starts at Nationals Park, and 2-0 with a 3.80 ERA in four starts in September. The Phillies counter with rookie Jerad Eickhoff, who is 1-3 with a 3.16 ERA in his last six starts.

2. Bryce Harper - He leads the National League in batting average (.339) and home runs (41). He's batting .340 with eight home runs versus the Phillies this season.

3. X-Factor - The Nats are 6-1 in the last seven head to head meetings between the two teams, and all but one of those games were decided by more than one run.
