It’s fairly common for a Major League Baseball player to excel in either power or speed, but very few players are masters of both crafts.

One of baseball’s most elusive milestones is the so-called “40-40 club,” which is reserved for players who hit 40 home runs and steal 40 bases in a single season. It’s such a rare feat that, in the nearly 150 years of organized MLB league play, only four players in history had accomplished it prior to 2023.

That changed on Friday, though, as Atlanta Braves right fielder Ronald Acuña Jr. knocked his 40th home run of the season, becoming the fifth player to join the exclusive club. He’s also the first player to do so since Alfonso Soriano in 2006 with the Washington Nationals.

Here’s a look at the complete current list of players that comprise MLB’s 40-40 club.
