Michael Wacha powered through the heart of the Giants order the first two times he faced them but he couldn't do it a third time and the Giants pulled even with the Cardinals 1-1 in the sixth.
Matt Duffy and Brandon Belt started the inning with singles off Wacha. Hunter Pence grounded into a double play, with Duffy taking third as Kolten Wong fielded a grounder, tagged out Belt and threw out Pence at first.
Shortstop Brandon Crawford then doubled off the center field wall to score Duffy with the tying run. Andrew Susac grounded out to end the inning.
