Pirates 5, Cardinals 3: Russell Martin hit a game-tying two-run homer in the seventh inning and later doubled and scored as visiting Pittsburgh rallied after St. Louis pulled starter Jake Westbrook.

Westbrook tossed six scoreless innings but watched as the bullpen gave away his chance at career win No. 100. Martin homered off Joe Kelly (0-1) in the seventh and Andrew McCutchen later drew a bases-loaded walk against Trevor Rosenthal to snap the 2-2 tie.

The seventh-inning rally made a winner of A.J. Burnett (2-2), who allowed two runs in six innings. Tony Watson worked around a leadoff walk in the seventh, Mark Melancon survived a leadoff double in the eighth and Jason Grilli allowed an RBI double to Carlos Beltran in the ninth before securing his league-leading 10th save.

Westbrook stranded runners in four innings and got an inning-ending double play in the fifth. Although he had thrown an average of 109 pitches in his first three starts, he was lifted after just 91 in this one and the Pirates took advantage right away.

After Pedro Alvarez singled and Martin homered to tie it, Pittsburgh loaded the bases on a base hit, a walk and a hit batter before Rosenthal walked McCutchen and Garrett Jones had an RBI groundout to make it 4-2. Martin doubled and scored in the eighth to make it a three-run margin as the Pirates won for the seventh time in nine games.
