Chicago at St. Louis

The Chicago Cubs have won 2-of-3, cashing as a dog of +113 and +170. The offense is clicking, scoring 18 runs the last three games. Southpaw starter Paul Maholm is a veteran arm off a fine season with a 3.66 ERA allowing fewer hits than innings pitched, plus he has a 3.72 ERA against St. Louis in 92 career innings. The Cardinals are 2-7 in their last nine home games vs. a left-handed starter. 24-year-old Jake Westbrook has average stuff and doesn't deserve to be this big a favorite, off a season where he was 4-5 at home with a 5.32 ERA. Opponents hit .290 off him for the entire 2011 season and the Cardinals are 1-4 in Westbrook's last five starts as a home favorite. Play the Cubs.
