Ronald Acuna Jr. has once again raised some eyebrows with his lack of hustle on the bases.

The Atlanta Braves outfielder led off the seventh inning of Game 1 of the NLDS against the St. Louis Cardinals on Thursday, mashing a long fly ball to the right-field corner that nearly turned into a home run. It should have been an easy double, but Acuna was slow to get up the line in anticipation of a round-tripper and instead ended up with a long single.

The slow trot came back to bite the Braves when the next hitter, Ozzie Albies, grounded out. Acuna advanced to second on the play but would have been 90 feet from scoring had he legged out for the double. He was then doubled off second when Josh Donaldson lined out to the shortstop to end a promising inning.

Acuna’s gaffe came under the microscope a half-inning later when St. Louis tied the game. The Cardinals then scored four runs in the ninth to take the lead. Although Acuna homered late, St. Loius held on to take Game 1 by a score of 7-6.

Ronald Acuna Jr. is one of the most talented young players in baseball, but he had to be taught a hard lesson Sunday.

The outfielder hit a long fly ball off the wall in the third inning against the Los Angeles Dodgers but failed to run it out, thinking it was a home run. It ended up being a single, and he failed to score in the inning.

Manager Brian Snitker decided to pull him from the game to teach him to hustle on every ball in play

“You’ve got to run. That’s not going to be acceptable here,” Snitker said, per David O’Brien of The Athletic. “...The name on the front is a lot more important than the name on the back.”
