The set-up: While I obviously wouldn't be completely shocked by an outright upset, I'm going to recommend laying what I feel to be a very reasonable mid-sized price for the extra run-and-a-half. The visitors go with Carlos Martinez and the home side goes with Kyle Hendricks.

The pitchers: Martinez is so far 6-5 with a 3.08 ERA. He most recently beat the Giants, giving up one run off six hits over seven innings while striking out three. It was Martinez's third straight victory and his ninth quality start of the season. After a small shaky stretch, Martinez is back on track across the board and he'll now look to improve upon his respectable 4-3, 3.57 ERA record on the road.

Hendricks is so far 6-8 with a 3.92 ERA. He most recently gave up one run over eight innings in a no-decision against San Francisco. Starts like that though were few and far between over the first half for Hendricks, who has just two quality efforts out of his last nine trips to the hill.

The pick: Take it for what you will, but St. Louis is 7-2 in its last nine when playing with three or more days rest, while Chicago is just 15-17 in its last 32 when playing with three or more days of rest. Martinez comes in as the much more consistent hurler and there's no reason not to think that the hard-throwing right-hander won't keep that momentum rolling with extra time off. Hendricks comes off a strong start, but I believe his inconsistencies come back to haunt him again. Play on St. Louis on the run-line.
