Aroldis Chapman worked a perfect ninth for his sixth save in six chances, finishing off only the third road victory in 11 games for the Reds and handing St. Louis its third straight loss.
Wainwright (4-2) trailed just six pitches in after Shin-soo Choo doubled on his first offering, advanced on a sacrifice and scored on Votto's single. Over his final six innings, the right-hander gave up three hits and one run on Paul's broken-bat forceout grounder in the fourth set up by hits from Brandon Phillips and Todd Frazier.
Wainwright walked two, one intentionally, after issuing just one in 37 1-3 innings his first five starts.
Latos (2-0) worked around five hits and three walks in his sixth quality start in as many outings this season. The Reds have scored just four runs in his last three appearances.
The Cardinals, who entered with a major league-leading .355 average with runners in scoring position, had two base runners in an inning four times against Latos. Allen Craig, who came in 7 for 11 with runners in scoring position and two outs, failed twice in that situation with forceouts to end the third and fifth innings.
NOTES: Jaime Garcia (2-1, 2.89 ERA) has eight wins over the Reds - double that of any other opponent - entering Tuesday's start against Bronson Arroyo (2-2, 4.24). Arroyo is 8-14 against the Cardinals and has lost his last two starts, including a 5-1 loss on April 9 in St. Louis. ... Carlos Beltran did not start a day after being taken out of the game with flu-like symptoms, but flied out as a pinch hitter in the eighth. ... Molina is 2 for 2 on steals after catching Latos napping and taking third without a play in the fourth. ... David Freese is in an 0-for-16 slump that has dropped his average to .163 after failing to get the ball out of the infield in four at-bats. Daniel Descalso also is hitless in 16 at-bats after a pinch-hit groundout in the seventh.
