The 30-30 club is a grouping of players who have reached the 30 stolen base and 30 home run plateaus in the same season.

The term "club" is used rather loosely, as it is generally used by sports writers and fans to group players together under a common heading. The word "club" was likely coined based on the original exclusiveness and rarity of a 30-30 season. Statistically, the 30-30 club is of note due to the pairing of power and speed - two measurements usually isolated from one another. For example, a slugging first baseman would not usually accumulate high stolen base totals. Likewise, a speedy center fielder may be more adept at stealing bases, but may not supply much power. Thus, many players may be able to either steal 30 bases or hit 30 home runs, but only a rare handful may be able to do both.

Trends and Breakdown [ edit ]

Recent trends show that club membership has steadily increased since the 1970s. Ken Williams was the first player to reach the mark in the major leagues in 1922 with 39 home runs and 37 stolen bases. He was the sole member of the club for 34 years until Willie Mays had back-to-back 30-30 seasons in 1956 and 1957. Occurrences then began to increase thereafter, as there were 2 in the 1960s, 5 (4 by Bobby Bonds) in the 1970s, 7 in the 1980s, 20 (5 by Barry Bonds) in the 1990s, and 17 (4 by Alfonso Soriano) in the 2000s.

Most 30-30 seasons come from players who play the outfield, particularly left and right field. However, several center fielders have enjoyed 30-30 seasons, including Willie Mays, Dale Murphy, Eric Davis, Preston Wilson, Carlos Beltran, Grady Sizemore, Jacoby Ellsbury, Matt Kemp and Mike Trout. The remaining breakdown is as follows: shortstop (4) (Barry Larkin, Alex Rodriguez, Jimmy Rollins, Hanley Ramirez); third base (4) (Tommy Harper, Howard Johnson, |, David Wright); second base (3) (Alfonso Soriano, Brandon Phillips, Ian Kinsler); first base (2) (Joe Carter, Jeff Bagwell). There has not been a 30-30 season recorded by a player who predominately plays catcher or pitcher.

There have been 62 30-30 seasons by 40 different players. Barry and Bobby Bonds account for 10 of those seasons.
