The set-up: While far from perfect, I still think that the Cardinals' Carlos Martinez is well worth the price of admission in this particular matchup, as the Reds send the erratic Matt Harvey to the hill.

The teams: Harvey is so far 4-5 with a 4.80 ERA. Most recently he gave up three runs off nine hits and a walk over 5.2 innings in a no-decision to the Cubs on Saturday. Harvey has looked decent over a five-start stretch by posting a 2.48 ERA, but I'll point out that he's still only 1-4 with a 5.15 ERA on the road this season.

Martinez is so far 6-4 with a 3.05 ERA. He most recently gave up one run off six hits over seven innings with three strikeouts in a victory over San Francisco on Saturday. It was Martinez's third straight win and he'll now be looking to improve upon his 2-1, 2.38 ERA home record.

The pick: Harvey has been anything but trustworthy over the last few seasons and while he has admittedly looked better of late, I think he's going to stumble in this difficult venue. Martinez is the correct call here, as I expect him to come in focused in friendly confines. This one has blowout written all over it, play on hard-hitting St. Louis.
