Stud versus underachiever. That's what we have in this matchup. Carlos Martinez doesn't get a lot of publicity, but he's a star and he's at his best on the road.

Andrew Cashner has been a dud the past couple of years after showing early promise. Going from the Padres to the Marlins isn't going to change that.

Let's begin with Martinez, who is having another superb season at 10-6 with a 2.87 ERA. He's 6-1 with a 1.89 ERA in eight road outings this season. St. Louis has won 77 percent of his past 22 away starts.

Now let's examine Cashner. His ERA was 4.34 last year. This season he's 4-7 with a 4.76 ERA. Cashner is 15-30 during the last three years. He hasn't reached the seventh inning in any of his last seven starts. The Marlins have bullpen fatigue issues after starter Colin Rea only went 3 1/3 innings on Saturday.

The Cardinals own the best road mark in the majors at 31-18. This is a bounce back game for them after an embarrassing 11-0 loss yesterday.
