St. Louis Cardinals: Kyle Lohse  (12-2; 2.72 ERA)

Kyle Lohse will look to continue his dominant season tonight, carrying a 6-1 record and a 2.40 ERA in 11 starts at Busch Stadium. in St. Louis this year. Though he did not receive the win in his last start against the Philadelphia Phillies, he was very solid allowing one run and four hits over seven innings while striking out a season-high seven batters.

THE SKINNY: 

Arizona has lost 8 of their past 11 games and are quickly falling behind in this wild card race while the Cardinals are only improving. They have been unable to hit with runners in scoring position as of late (0-for-6 in the series) and have a tough challenge tonight as they go up against Kyle Lohse, who has not tended to allow a lot of base runners at all in his most recent few starts.
