ATLANTA — Tyler Kinley knew the wet conditions Wednesday night at Truist Park were going to make it tough to grip the baseball. That didn't stop the Colorado Rockies relief pitcher and others in the bullpen from shutting down the Atlanta Braves.

"There's not going to be any stat line that's going to say it was wet out there or the ball was slippery or it's been raining for six hours," Kinley said after pitching a scoreless eighth inning. "We said we need to figure this out and get through it."

Raimel Tapia hit a tiebreaking single off A.J. Minter in the 10th inning, scoring Colton Welker from third base and lifting Colorado to a 3-2 victory over Atlanta on Wednesday night.

Atlanta's lead in the National League East was trimmed to 3 1/2 games over the second-place Philadelphia Phillies as the Braves attempt to win the division for the fourth straight year.

Colorado is 10 games below .500 and 28 games back in the NL West standings.

Robert Stephenson earned his first save in two chances in the bottom of the 10th, striking Austin Riley, hitting Adam Duvall with a pitch, striking out Travis d'Arnaud and getting Dansby Swanson to pop up.

"They did great in a game that you had to do great," Colorado manager Bud Black said. "In a low-scoring game, on the road, against a division leader, in their ballpark, in the rain, on a long night, I'm proud of our guys. I'm proud of our bullpen. I'm proud of our players."

The game was played in a steady drizzle, and the grounds crew spent much of the night between innings pouring dirt and raking the infield, the mound and the area around home plate.

Welker, who began the 10th on second base for Colorado per tiebreaker rules, advanced on a groundout and crossed the plate when Tapia, a late-inning replacement, drove the ball into left field.

Minter (2-6) took the loss. Carlos Estévez (3-4) faced five batters in the ninth to earn the win.

The Rockies scored twice in the fifth to take a 2-1 lead against Braves starter Huascar Ynoa. Sam Hilliard and Welker began with consecutive singles, and Hilliard advanced on a flyout and then scored on pitcher Antonio Senzatela's sacrifice bunt.

Ynoa walked Garrett Hampson to load the bases, struck out Brendan Rodgers and walked Charlie Blackmon. That chased Ynoa. Jacob Webb then struck out Trevor Story to strand three runners and end the threat.

The Braves took a 1-0 lead in the second off Senzatela when Riley singled, advanced on Swanson's single and scored on Eddie Rosario's single.

Rosario's 11th homer of the season sailed into the right-field seats and tied it at 2 in the fifth. Rosario, from Puerto Rico, wore No. 21 to honor Roberto Clemente on Major League Baseball's Roberto Clemente Day.

"For me, it was real important to wear that number," Rosario said through a translator. "As Puerto Ricans, he's the example we try to follow on and off the field. More than anything, a battle I've taken up and all of us Puerto Ricans have taken up is to try to get his number retired across all of MLB. Hopefully we can gain some traction with that argument."

Ynoa, who gave up two runs and four hits with two walks and eight strikeouts in 4 2/3 innings, is winless in his past six starts since returning Aug. 17 from the injured list but has a 3.58 ERA during that stretch.

Senzatela allowed two runs and seven hits with no walks and seven strikeouts in six innings. He has a 3.16 ERA over his past 10 starts.

Atlanta right-hander Luke Jackson struck out the side in the eighth, and the Rockies whiffed 13 times total.

The Rockies are 23-51 on the road this season but have won six of their past seven and nine of their past 14 games away from Coors Field. They began the season 6-31 away from Denver but are 14-17 since the All-Star break on the road.

Colorado will try to sweep the three-game series by sending out Germán Márquez (12-10, 3.93 ERA) to oppose fellow right-hander Ian Anderson (7-5, 3.61) of the Braves in a matinee matchup Thursday.
