Summer fun: National League's best clash for three-game set at Busch

The Pittsburgh Pirates and St. Louis Cardinals, the teams with the two best records in the National League, have played to a stalemate through 10 games this season.

Despite being on a pace for almost 100 wins, the Pirates have work to do to catch the NL Central-leading Redbirds.

The Cardinals' pitching staff is having an historic season up to this point.

The Cardinals have been wildly successful all year when either Carlos Martinez or Michael Wacha (tomorrow night's starter) get the start.

Matt Carpenter is having one of the best home-run hitting seasons ever for a Cardinals' hitter batting at the top of the order.
