ATLANTA — Jason Heyward might be staying in the leadoff spot.
Heyward homered and drove in two runs to help the Atlanta Braves beat St. Louis 5-2 on Sunday night, capping their first three-game sweep of the Cardinals at home in 10 years.
Heyward hit leadoff for the second consecutive night and only the third time this season. He has nine homers, including two in the series between NL division leaders.
"I'm getting more comfortable in general," Heyward said. "The more you move, it is hard to get comfortable."
When he moved Heyward to the leadoff spot on Saturday, Braves manager Fredi Gonzalez said he was "just tinkering." After Sunday night's game, Gonzalez said he's sticking with Heyward atop the lineup "right now, the way we set up."
Gonzalez said the "common denominator" in the three-game sweep was dominant starting pitching.
Following strong starts by Mike Minor and Julio Teheran, Kris Medlen (7-10) allowed two runs on eight hits and a walk in six innings to snap his three-game losing streak.
The three wins came after Tim Hudson, the leader of the staff, sustained a season-ending broken right ankle Wednesday night in New York.
"Nobody needs to be Huddy," Gonzalez said. "Nobody needs to be the ace or that kind of label. Believe me, I'm going to fight that the next two months when we're pitching well. Collectively, I think, as a unit you circle the wagons, you go out there and you get those three performances that we had."
The Cardinals, who lead the NL in batting average and scoring, were held to three runs in the series.
"Obviously, going in we had confidence that we could control their lineup, but knowing the kind of lineup that they have, I'm trying to avoid saying that we were surprised they scored only three runs in the series," Medlen said. "I just think it's how good we are as a staff and as a bullpen. Mike Minor and Julio did a great job and I just wanted to continue that."
The Cardinals aren't accustomed to such meager offense.
"Their guys threw well," manager Mike Matheny said. "I think we probably weren't as locked in as we've been a good portion of this season either, so that makes for a tough combination."
The Braves broke a 2-all tie with two runs in the sixth inning off rookie Shelby Miller (10-7) and two relievers. Pinch-hitter Joey Terdoslavich drove in Chris Johnson with the go-ahead run. Heyward added another run-scoring single.
Miller allowed three runs, two earned, on six hits and two walks in 5 2-3 innings.
The Cardinals were swept in a road series for the first time this season.
"You never want to go into a place and get swept," Miller said. "We were battling the whole time. I don't think we had a terrible series, we just didn't come out on top in any of the games."
The Braves finished their first three-game sweep of the Cardinals at Turner Field since April 2003.
Atlanta relievers Luis Avilan, Jordan Walden and Craig Kimbrel combined for three scoreless innings. Kimbrel pitched a perfect ninth to take the NL lead with his 31st save.
Johnson singled with two outs in the second, moved to third when the ball bounced past Carlos Beltran in right field for an error, and scored on a single by Andrelton Simmons. Heyward's line-drive homer to the front row in right field pushed the lead to 2-0 in the third.
The Cardinals pulled even with two runs in the fifth. Back-to-back doubles by Pete Kozma and Miller produced the first run.
With two outs, Beltran hit a fly-ball single to left field that fell between Evan Gattis and Simmons, who sprinted into the outfield from his shortstop position. Gattis, a natural catcher, was playing deep for the power-hitting Beltran and was slow to break on the ball.
The Braves' two-run sixth began with two outs. Johnson, who entered the night tied with Cardinals catcher Yadier Molina for the NL lead with a .332 batting average, singled for his second hit and moved to third on Simmons' second single. Terdoslavich and Heyward followed with run-scoring hits.
Johnson added his third hit, a double, off Fernando Salas in the eighth to push his average to .338. Reed Johnson reached on an infield single, and Chris Johnson scored on a throwing error by Kozma from shortstop.
Reed Johnson pulled up with an apparent injury after running to first and was replaced by pinch-runner Jose Constanza.
The Braves made two strong defensive plays. Simmons went to his right, falling to his knees, to snag a grounder by David Freese before throwing to second to start a double play in the second. Freddie Freeman leaned over the railing in front of the Atlanta dugout to catch a foul popup by Matt Holliday to end the eighth.
