McCann hit a two-run double in the top of the ninth off closer Ryan Franklin and the Atlanta Braves held on to beat the St. Louis Cardinals 7-6 on Saturday.
"I put together a good at-bat there in the ninth," McCann said. "I was just trying to get a pitch up in the zone and I hit it a little better and it reached the wall."
Franklin (2-3) blew his second consecutive save -- and fourth of the season -- as the Cardinals dropped two in a row for the first time since July 25-26 when they lost consecutive games to Philadelphia.
Mike Gonzalez (4-4) allowed two runs in the eighth which gave the Cardinals a 6-5 lead. Rafael Soriano closed out the game for Atlanta for his 24th save.
After the game, Braves manager Bobby Cox was smoking a victory cigar.
"That's a good one, you bet," Cox said. "You can never get down. Franklin's done an unbelievable job but like I tell my guys, anything can happen."
The Cardinals rallied to take the lead in the eighth on a run-scoring single by Yadier Molina and an RBI groundout by Brendan Ryan.
Franklin fell apart in the ninth, allowing three hits and a walk. Nate McClouth led off with a double and Martin Prado singled him to third before Chipper Jones walked to load the bases.
"I'm not one to lean on excuses," Franklin said. "I just would rather say I didn't get it done."
McCann followed with a double to center that left runners on second and third with no outs, but Franklin escaped further damage with two strikeouts and a pop out.
Atlanta starter Tim Hudson allowed four runs and 10 hits in five-plus innings. He walked two and struck out one. His biggest contribution was his first career home run, a two-run shot in the second that gave the Braves a 3-2 lead.
"Obviously its been a while since I've trotted around the bases like that," he said. "I was really scared I was going to go my whole career without hitting one but it was exciting. It felt as good or better than any shutout I've thrown."
Kyle Lohse made his first start since Aug. 21 after returning from the disabled list with a groin strain. He allowed four runs in 3Q innings pitched, his third shortest start of the year.
Cardinals manager Tony La Russa was ejected by home plate umpire Greg Gibson for arguing balls and strikes after the sixth inning. It was La Russa's first ejection of the season.
"I feel like when the tape is reviewed," La Russa said. "They'll see there were some close calls that we had a reason to question. You still play the game. Umpires don't beat you."
