Atlanta Braves’ Ronald Acuña Jr. made history by becoming the first MLB player to achieve a 30-home run and 60-stolen base season, hitting his 30th homer in a grand slam against the Los Angeles Dodgers.

This accomplishment also makes him the third player to have a 30-50 season, alongside Barry Bonds and Eric Davis. Prior to Acuña, Rickey Henderson held the record for the most home runs with 60-plus steals in a single season with 28 in 1986 and 1990.

Acuña, a 25-year-old outfielder, is a top contender for the NL MVP and plays for the leading Braves, who have 88 wins as of September.
