St. Louis, MO -- (Sports Network) - Ryan Ludwick finished 3-for-4 with two runs batted in, as St. Louis used a four-run eighth inning to upend Milwaukee, 5-3, and earn a split in the two-game set with the Brewers.

Albert Pujols and Yadier Molina each had two hits, while Aaron Miles drove in the go-ahead run for the Cardinals, who have won four of six. St. Louis also moved within 3 1/2 games of first-place Milwaukee in the NL Wild Card standings.

Adam Wainwright allowed three runs -- two earned -- on eight hits in a six- inning start for the Cardinals, but didn't factor into the decision. Ryan Franklin (5-5) threw a scoreless eighth to earn the win.

David Riske (1-2) took the loss for the Brewers after giving up three runs in the eighth. Starter Manny Parra was solid in six-plus innings, as he gave up one run on six hits and struck out seven for Milwaukee, whose five-game win streak ended.

The Brewers also fell to six games back of the Chicago Cubs for first in the NL Central.

Mike Cameron and Jason Kendall each finished with two hits and an RBI, while J.J. Hardy had three hits and drove in a run for the Brewers.

The Cardinals trailed by two heading into the bottom of the eighth, but got a rally started when Pujols hit a lead off double off Riske. Ludwick followed with another double to plate the run, and Troy Glaus singled to tie the game.

After Riske got Molina to ground out, Brian Shouse came on in relief to face pinch-hitter Miles with Glaus on third. Miles sent a grounder to shortstop, but Glaus slid under the tag as Hardy went home with the throw.

Braden Looper sacrificed Miles to second with a bunt and Felipe Lopez singled to center to bring another run home for a 5-3 lead.

Chris Perez entered for the Cardinals in the ninth and gave up a one-out double to Hardy. However, he struck out Ryan Braun and Prince Fielder to end the game and notch his sixth save.

Hardy's RBI single in the third inning plated Kendall, who had singled, went to second on an error and advanced to third on a bunt. In the fourth, consecutive doubles from Corey Hart and Cameron gave the Brewers another run. A ground out put Cameron on third base for Kendall, whose single made it 3-0, Milwaukee.

Ludwick hammered a two-out pitch from Parra in the sixth for a solo homer to bring St. Louis within two.
