He's far from a household name, but Luke Weaver may be the hottest pitcher in baseball. The Cardinals right-hander is 5-0 with a 1.15 ERA during his last five starts. The Cardinals have won these five games by a combined margin of 22 runs.

The Cardinals are in must-win mode trailing Colorado by 3 1/2 games for the second NL wild-card spot.

The Cardinals have gotten healthy, too, with power-hitting middle infielder Jedd Gyorko back on the field. Matt Carpenter should be in the lineup, too, after getting a day off on Tuesday.

The Reds are in rebuild mode pitching different rookies nearly every game. Today the Reds are going with one of their lesser arms, Rookie Davis. And, yes, Rookie is rookie. He's 1-2 with a 7.58 ERA in five big league starts.
