ATLANTA (AP) -- Freddie Freeman's single to the center-field wall scored Jason Heyward from second base with two outs in the 10th inning on Sunday, lifting the Atlanta Braves to a 1-0 win over the Cincinnati Reds.
Cincinnati's Johnny Cueto and Atlanta's Julio Teheran each allowed only three hits in eight scoreless innings before giving way to relievers.
With two outs in the 10th, Heyward hit a single up the middle off J.J. Hoover (1-3). B.J. Upton followed with a grounder that bounced off Hoover's glove toward shortstop for an infield hit.
Left-hander Manny Parra was summoned to face Freeman, who hit a drive that bounced on the warning track beyond center fielder Billy Hamilton's reach.
Braves players swarmed Freeman at second base following the sweep.
Reds manager Bryan Price and pitcher Homer Bailey were ejected in the first inning after a replay ruling went against them.
Cueto struck out 11. He has allowed only one run in his last three starts, leaving him with a 1.15 ERA.
Teheran also has given up just one run in his last three starts and is a big reason the Braves' starters led the majors with their 1.65 ERA entering the day.
The Reds couldn't take advantage of a scoring opportunity in the 10th.
Ryan Ludwick hit a one-out single off David Carpenter and moved to second on Zack Cozart's two-out single. Pitcher Mike Leake pinch-ran for Ludwick at second base.
Atlanta left-hander Ian Thomas (1-0) ended the threat by getting pinch-hitter Roger Bernadina to pop up.
Cueto, coming off back-to-back, complete-game wins over Pittsburgh, finished one strikeout away from his career high of 12 set April 16 against the Pirates.
Teheran struck out five and walked two. Jordan Walden maintained the impressive pitching by recording two strikeouts in a perfect ninth.
Price asked for a replay after first-base umpire Greg Gibson called Upton safe on a pickoff throw from Johnny Cueto. The replays shown on the video board indicated first baseman Joey Votto may have applied the tag before Upton reached the bag.
Price came back out of the dugout after the ruling that the call stands, meaning there was not "clear and convincing" evidence to overturn it. Price was ejected by crew chief Bill Miller, the second-base umpire. Miller also tossed Bailey, who argued from the Reds' dugout.
Upton, who has worn prescription glasses for the first time in this series, lost Brayan Pena's fly ball in center field in the sun in the second inning.
Upton, who was not wearing flip-down shades over his new glasses, had the ball hit off his glove and fall to the ground. Pena, awarded a double, was stranded at second base.
