Ronald Acuna Jr. of the Atlanta Braves. scratched his back from the tension of the line-up

PHILADELPHIA — The Atlanta Braves scratched Ronald Acuna Jr. Thursday night because of a back strain.

Acuna, 24, had started Atlanta’s previous 19 games. The three-time All-Star has played in a total of 110 games since returning in late April from a torn right ACL that ended his 2021 season.

“He had some back pain at the end of batting practice,” Braves manager Brian Snitker said after Atlanta’s 1-0 loss to the Philadelphia Phillies on Thursday night. “He wobbled a little bit in the cage and something hit him and he wasn’t available.”

Acuna is everyday. He is hitting .270 with 13 homers, 46 RBI and 28 stolen bases this season.

“We’ll treat him and see if he’s available and ready to go tomorrow,” Snitker said. “He wasn’t into it. It was just one of those things.”

Robbie Grossman replaced Acuna in right field in the opener of a four-game series in Philadelphia. Dansby Swanson moved into the leadoff position.

The Braves trailed the idle New York Mets by 1½ games in the NL East after Thursday night’s game with 12 games to play. The teams have a three-game series in Atlanta next weekend.
