Atlanta Braves star Ronald Acuna Jr. made a champion-esque move this week … by visiting and donating 113,000 face masks to an Atlanta children’s hospital the day after winning the World Series!!

The awesome visit happened on Thursday — right after Acuna’s Braves took home the Commissioner’s Trophy and beat the Houston Astros in Game 6 of the 2021 Fall Classic.

The outfielder popped up at the Children’s Healthcare of Atlanta — surprising fans including 11-year-old Nolan Madsen, who’s a patient at the Aflac Cancer and Blood Disorders Center.

It turns out Nolan’s hero is Acuna — and he was in total shock when he came face to face with the superstar, who later handed him a signed #13 jersey and posed for pics with him!!

That wasn’t the only thing Acuna gave away during his stop … he also donated 113,000 masks to the hospital as a thank you for their hard work and dedication during the COVID pandemic.

“This day is for the kids,” Acuna says. “I get to smile, and feel happy that I’m a World Series champion. They helped me get that. It’s only right if I can give that smile back.”

The hospital thanked the 23-year-old via IG for the great gesture .. saying, “Thank you Acuna for making this incredible week even better for our kids! ⚾”
