Matt Carpenter led off with a walk but Lance Berkman and Carlos Beltran each flew out to put St. Louis on the brink of a loss. Rafael Furcal, however, kept the rally alive with a single and Skip Schumaker coaxed a walk to load the bases.
Matt Holliday then grounded a single into right field for two runs, tying the game and sending Schumaker to second. Craig followed the decisive blow -- looping an 0-2 pitch into left for the go-ahead RBI single.
Jason Motte (4-3) earned with victory with 1 2/3 scoreless innings as the Cards took the opener of a three-game series.
Corey Hart socked a solo homer for Milwaukee.
