There's nothing wrong with St. Louis' offense - fourth in the majors in runs and sixth in homers - and now the Cardinals have a strong pitching matchup edge with a rejuvenated Adam Wainwright drawing Tom Koehler.

The buy sign is on with Wainwright as he's returned to ace status holding the Brewers and Pirates to a combined one run in his last two starts spanning 14 innings. Wainwright tied his season high in strikeouts against the Pirates with nine.

Wainwright has a good post-All-Star history (50-28 with a 3.05 ERA) and is 4-2 with a 2.33 lifetime ERA versus the Marlins in eight starts.

Koehler historically is worse on the road and that's held up this season with a 4.72 away ERA compared to 4.22 ERA at Marlins Park. Koehler has a career WHIP at 1.56 and a 7.56 lifetime ERA versus St. Louis in three starts. Koehler is vulnerable to the Cardinals' power bats, too. He didn't allow a homer in his last start, but surrendered four during his previous three outings.

The Marlins are 0-7 the past seven times Koehler has started versus an above .500 opponent.
