In Major League Baseball (MLB), the 30–30 club is the group of 51 batters who have collected 30 home runs and 30 stolen bases in a single season. Baseball Digest called the 30–30 club "the most celebrated feat that can be achieved by a player who has both power and speed." Six members have been elected to the National Baseball Hall of Fame.
Background
Ken Williams was the first to achieve this, in 1922. He remained the sole member of the club for 34 years until Willie Mays achieved consecutive 30–30 seasons in 1956 and 1957. Bobby Bonds became the club's fourth member in 1969; he subsequently became the first player to achieve the mark in three, four, and five seasons. His son Barry Bonds is the only other player with five 30–30 seasons.
In total, 51 players have joined the 30–30 club, with 19 achieving it multiple times, resulting in 80 individual seasons overall. Of these 51, 30 were right-handed batters, 15 were left-handed, and six were switch hitters. Twelve of the 51 players (including seven active members of the 30–30 club) have played for only one major league team. The New York Mets are the only franchise to have five players reach the milestone, and have had the most individual 30–30 seasons (8) as well (Howard Johnson did it three times, Francisco Lindor two). The Atlanta Braves, Cincinnati Reds, Cleveland Indians, Colorado Rockies, Los Angeles Dodgers, and San Francisco Giants each have had three players reach the milestone. 6 franchises, the St. Louis Cardinals, San Diego Padres, Tampa Bay Rays, Detroit Tigers, Minnesota Twins, and Chicago White Sox, have never had a 30-30 season. Although Bobby Bonds played for the White Sox for part of his 31 home run, 43 stolen base 1978 season, he only hit two home runs and stole six bases during his time in Chicago that season; the other team Bonds played for in 1978, the Texas Rangers, does not get credit for his 30–30 season either, as he hit only 29 home runs in Texas that season. The only other player to play for multiple franchises in a 30–30 season is Carlos Beltrán in 2004, who amassed 15 home runs and 14 stolen bases with the Kansas City Royals before being traded to the Houston Astros and hitting 23 home runs and stealing 28 bases.
Jose Canseco is the heaviest player to record a 30–30 season, reaching the mark at 240 pounds (108.9 kilograms) in 1988, while the lightest are Tommy Harper (1970), Eric Davis (1987), and Sammy Sosa (1993 and 1995) at 165 pounds (74.8 kilograms). Darryl Strawberry (1987) is the tallest player to achieve the milestone at 6 feet 6 inches (198.1 centimetres), while the shortest are Jimmy Rollins (2007) and Cedric Mullins (2021), both standing 5 feet 7 inches (170.2 centimetres).
Five players – Hank Aaron, Barry Bonds, Willie Mays, Alex Rodriguez and Sammy Sosa – are also members of the 500-home-run club, and Aaron, Mays and Rodriguez are also members of the 3,000-hit club. Dale Murphy, Jose Canseco, Barry Bonds, Larry Walker, Jimmy Rollins, Ryan Braun, Mookie Betts, Ronald Acuña Jr., and Shohei Ohtani won the Most Valuable Player (MVP) Award in the same year as their 30–30 season; Bonds did so twice, in 1990 and 1992. Mays and Rollins also reached the 20–20–20 club in the same season. A single season has seen as many as seven players accomplish 30–30; this happened only once, in 2025 (Corbin Carroll, Jazz Chisholm Jr., Pete Crow-Armstrong, Francisco Lindor, José Ramírez, Julio Rodríguez and Juan Soto). The feat has been accomplished by teammates three times: the 1987 New York Mets (Darryl Strawberry and Howard Johnson), the 1996 Colorado Rockies (Ellis Burks and Dante Bichette) and the 2025 New York Mets (Juan Soto and Francisco Lindor). Bobby Witt Jr. of the Kansas City Royals was the first shortstop to achieve multiple 30–30 seasons, reaching this milestone in both 2023, with 30 home runs and 49 stolen bases, and 2024, with 32 home runs and 31 stolen bases, before being joined by Francisco Lindor who had his first 30-30 season in 2023 having both 31 home runs and stolen bases, then doing it again in 2025 with 31 home runs and stolen bases. Mike Trout became the youngest member of the 30–30 club, doing so at the age of 20 in 2012. The oldest players to record a 30–30 season did so in their age-32 season: José Ramírez (2025), Barry Bonds (1997), Dante Bichette (1996), Ellis Burks (1996), Bobby Bonds (1978), and Ken Williams (1922). Eric Davis achieved a 30–30 season (37 home runs, 50 stolen bases) in 129 games in 1987, setting a record for the fewest games played by a player in a 30–30 season.
