 For milestones that encompass an entire career, batters must achieve 3,000 hits or 500 home runs; pitchers must amass 300 wins or 3,000 strikeouts.
 A fifth club exists for relief pitchers that have recorded 300 saves over a career.
 In addition, milestones achieved in a single season include hitting 50 home runs, while three other single-season statistical clubs—the 20–20–20 club, 30–30 club and 40–40 club — include achievements from multiple statistical categories.
In Major League Baseball (MLB), the 50 home run club is the group of batters who have hit 50 or more home runs in a single season.

 Ruth subsequently became the first player to reach the 50 home run club on four occasions, repeating the achievement in 1921, 1927 and 1928.
 He remained the only player to accomplish this until Mark McGwire and Sammy Sosa matched his feat in 1999 and 2001, respectively, thus becoming the only players to achieve four consecutive 50 home run seasons.
 Barry Bonds hit the most home runs to join the club, collecting 73 in 2001.
