ATLANTA -- Shane Greene blew his first save opportunity as Atlanta’s new closer and Luke Jackson saved the day in his first appearance as the former closer.

It was just that kind of game for the Braves, who ruined Trevor Bauer’s Cincinnati debut and preserved what had the makings to be a sparkling Dallas Keuchel effort. They claimed a 5-4, 10-inning victory over the Reds on Saturday night courtesy of Ronald Acuña Jr.’s walk-off single against Robert Stephenson.

“It seems like everybody loves that moment,” Braves catcher Brian McCann said. “The moment to win it. Guys just continue to come through in the big moment.”

As the Braves lengthened their National League East lead to seven games, there were plenty of key moments that set the stage for Acuna to lace Stephenson’s 0-2 slider past the third-base bag and into left field, easily scoring Adam Duvall, who had drawn the first of two walks Jared Hughes issued to open the inning.

This was Acuna’s first career walk-off hit, but it wasn’t his most influential plate appearance of the night. That distinction would go to the go-ahead bases-loaded walk he drew against Michael Lorenzen with two outs in the eighth. The 21-year-old outfielder showed discipline after he fell behind with a 1-2 count against Lorenzen, who accounted for three of the four walks Atlanta drew in the inning.

“We came to compete and they came to compete,” Acuna said through an interpreter. “Somebody has to lose, and we came out with the victory.”

While the Reds’ bullpen faltered, the Braves realized the value they gained by enhancing the depth of their bullpen with the Trade Deadline acquisitions of Greene, Mark Melancon and Chris Martin. Their arrival pushed Jackson to a lesser role. But he showed his character and great talent when he struck out each of the three batters he faced in the top of the 10th.

“I told him, ‘That’s how you respond to a situation like that,’” Braves manager Brian Snitker said. “He threw as well as he has all year in that inning. We’re going to need him. It just deepens our bullpen and shows we have some weapons down there.”

The new pieces
With Martin having provided a scoreless appearance on Friday, the Braves gave the eighth inning to Melancon, who stranded a pair of runners in a scoreless debut. Everything shaped up perfectly for Greene, until he allowed three ninth-inning singles, two of which had an exit velocity below 80 mph.

Tucker Barnhart’s game-tying bloop single to shallow left field had 71.6 mph exit velocity and a .070 expected batting average, per Statcast. Fortunately, Reds third-base coach J.R. House aggressively sent Jesse Winker, whose attempt to score a go-ahead run from second was denied by Adam Duvall, his former Reds outfield mate.

“That’s why [closers] have to have short memories,” Snitker said. “It wasn’t anything he didn’t do. He didn’t give up hard contact and Duvall makes a great play there.”
