ST. LOUIS – Adam Wainwright allowed two runs in six innings and the St. Louis Cardinals got home runs from David Freese and Allen Craig in a 5-2 victory over the Arizona Diamondbacks on Wednesday night.
Rafael Furcal's two-run triple in the sixth gave the Cards a three-run lead.
St. Louis homered twice for the second straight game and will go for a sweep of the three-game series behind 12-game winner Kyle Lohse on Thursday night.
The Cardinals are 5-0 against the Diamondbacks this year and have won seven straight dating to last year.
Wainwright (11-10) was 0-3 in April before starting to regain his form. He's 4-0 with a 2.04 ERA in his past five starts.
Arizona's Paul Goldschmidt hit a homer estimated at 456 feet, longest by an opposing player at seven-year-old Busch Stadium, in the fourth.
Goldschmidt's first homer in nine games came on a drive that soared over the visitor's bullpen in left. The distance of the homer is the fourth longest overall at Busch, and is 13 feet shy of Matt Holliday's stadium-record homer off the Cubs' Ryan Dempster on July 20.
Joe Saunders (6-9) allowed five runs in six innings, the first time the lefty gave up more than three runs in 11 road starts. He entered with a 2.49 road ERA, fourth-best in the league.
The Diamondbacks (58-59) have lost eight of 11 and dropped below .500 for the first time since they were 49-50 on July 26.
Freese ended a 0-for-20 slump with his 16th homer after Carlos Beltran doubled with two outs in the fourth to put the Cardinals up 2-1.
Craig hit his 18th to right-center in the fifth and the Cardinals got three straight hits from the bottom of the order capped by Furcal's liner into the right-field corner in the sixth.
Furcal was moved to the bottom of the lineup last week while battling back issues and a slump. He also doubled in the third for his first mulitihit game since July 24.
Edward Mujica and Mitchell Boggs each worked a scoreless inning. Jason Motte finished for his 27th save in 31 chances.
