Joey Votto homered with one out in the bottom of the ninth inning on Tuesday night, powering the Cincinnati Reds to a 7-6 victory over the St. Louis Cardinals after they blew a five-run lead for the second straight game.

Votto connected off left-hander Kevin Siegrist (4-1) for his fifth career game-ending homer and Cincinnati's third homer of the game. The Reds have won five of their last six games overall.

Cincinnati pulled ahead 6-1 with the help of Adam Duvall's three-run homer off Mike Leake, his fourth homer in five games. The Reds got Duvall from the Giants as part of a trade for Leake last July, and the right-hander signed with St. Louis in the offseason.

Left-hander John Lamb shut down the Cardinals with his 65 mph curveball, allowing only one earned run in a career-high 7 1/3 innings. That's when the major leagues' worst bullpen let another late lead get away.

Blake Wood gave up Jhonny Peralta's bases-loaded double in the eighth, cutting it to 6-4. Matt Carpenter tied it with a one-out, two-run double in the ninth off Tony Cingrani (1-2), the Reds' 12th blown save in 19 chances this season.

Carpenter tried to stretch his hit to a triple, setting up a potential go-ahead run, and was initially ruled safe at third, but the call was overturned after a review.

Jaime Garcia is 10-4 career against the Reds, he'll toe the rubber tonight for St. Louis opposite Alfredo Simon for Cincinnati.
