There's more than meets the eye in this matchup. The Cardinals are home for the first time since Sept. 18. They return as National League Central Division champions. So their concentration level could be off especially facing the lowly Pirates. It's also their first home game since Albert Pujols hit his 700th big league homer. That could mean pregame festivities to celebrate and more distractions for the Cardinals. 

The pitching matchup is Johan Oviedo versus Jack Flaherty. Name recognition certainly goes with Flaherty. But, again, more than meets the eye here.
Flaherty is on the comeback trail. He's 1-1 with a 4.97 ERA in four starts this year. Flaherty last pitched on Sept. 22. So he could be rusty. The Cardinals probably aren't going to stretch him out either trying to balance rest and with getting prepared for their upcoming playoffs. 

Oviedo won't lack motivation being a former Cardinal. He pitched brilliantly in his last start, blanking the Cubs on three hits in seven innings last Saturday.
