The best pitching matchup of the day pits Dan Haren against Justin Verlander. Haren still leads the American League with a 2.46 ERA, although he's coming off a period in which he's allowed 19 earned runs in 43 1/3 innings, a 3.95 ERA. Verlander's been shaky since 6/29, going 2-2 but allowing an ERA of 5.44.

The Diamondbacks try to continue their drive to the playoffs vs. the Nationals as John Lannan faces Brandon Webb. Lannan did a good job against Bonds in the game before the record breaker. Webb's posted a 2.21 ERA over his last thirteen starts, although it's only good for a 7-5 record. That pulls his seasonal ERA under 3.00.

Enjoy!
