ATLANTA — A big moment can inspire an entire team. For the Atlanta Braves, inspiration has come from both expected and unexpected sources while their biggest superstar continues searching for his best form.Ronald Acuña Jr. entered Monday’s homestand finale against the San Francisco Giants looking more like himself. Maybe he drew motivation from Ha-Seong Kim’s walk-off single against the Los Angeles Dodgers. Or from Chris Sale’s shutout to cap a sweep of the reigning back-to-back World Series champions. Or maybe Acuña’s strides during the Braves’ weekend sweep of the Colorado Rockies are the product of getting one night off a few days after the team returned from a disappointing 2-5 road trip.“That helps a lot,” Michael Harris II said. “I feel like there’s a lot of times where everybody on the team isn’t going to click, but when that happens, I feel like we’re going to be a really dangerous team, and it’s good to see (Kim and Sean Murphy) going too.”Atlanta owns a five-game lead in the National League East and the head-to-head tiebreaker over the Dodgers, which would give the Braves home-field advantage if the teams finish with the same record. At 82-55, the Braves’ record matches L.A. for the third-best mark in the majors.And there isn’t another player that sparks the Braves like Acuña, who has not been producing at his usual level. His .757 OPS and 13 home runs could be a product of struggles against four-seam fastball. One year after hitting .269 and slugging .558 against those pitches, he is hitting .135 and slugging .192.He has struggled to exploit pitches in the middle and upper third of the zone, with 41 of his 74 hits on four-seamers down and away.“Baseball is hard sometimes,” Acuña said. “You feel good sometimes, but you don’t have the results.”Acuña was in a 4-for-37 stretch with 13 strikeouts before manager Walt Weiss gave the outfielder Thursday off. He smacked a double with a 108.3 mph exit velocity off a fastball from Tomoyuki Sugano the next night, part of a three-hit game.“Yeah, I’m feeling better. I did a couple adjustments early hitting BP so I feel good,” Acuña said Friday. “A day off, sometimes it can help you.”The next day he roped a single that left the bat at 98.5 mph. On Sunday, he singled in the 10th inning, setting up Matt Olson’s walk-off hit. It marked the Braves’ seventh walk-off win of the campaign.Acuña went 6-for-9 against the Rockies with four walks and a few highlight-worthy plays on defense — including a sliding catch that saw him cover 114 feet of outfield grass.
