The 30-30 Club in MLB (History and Members)

The 30-30 club is MLB’s group of hitters who put up 30 home runs and 30 stolen bases in a single season, a combination of power and speed that most players can manage only one half of. It has been reached more than 75 times, which makes it the reachable cousin of the far rarer 40-40 club.

Ken Williams of the St. Louis Browns was the first, hitting 39 home runs and stealing 37 bases in 1922. Then nothing for 34 years, until Willie Mays did it in back-to-back seasons in 1956 and 1957. Since then the club has grown steadily, with several new members most decades and a handful of players clearing the bar over and over.

Who has the most 30-30 seasons

Two men hold the record, and they share a last name. Bobby Bonds reached 30-30 five times in the 1970s, and his son Barry Bonds matched him with five of his own between 1987 and 1996. No one else has more than four.

Ronald Acuna Jr.	2

Bobby Bonds was the trailblazer for repeat power-speed seasons, becoming the first player to reach 30-30 three, four, and five times. Barry then built one of the greatest careers in baseball history on the same skill set before his power numbers exploded in the 2000s. Alfonso Soriano is the only other player with four, all in the 2000s.

The recent surge in power-speed seasons

The 2020s have been the busiest era yet for the 30-30 club. Ronald Acuna Jr. cleared it in 2019 and again in 2023, when he stole 73 bases, the most by anyone who has ever gone 30-30. Julio Rodriguez, Jose Ramirez, and Bobby Witt Jr. are among the current stars who have reached the mark, and several hitters have joined in a single season more than once this decade.

Two milestones beyond 30-30 also arrived in this stretch and reset expectations entirely. Acuna posted the first-ever 40-70 season in 2023, and Shohei Ohtani produced the first 50-50 season in 2024. Both cleared 30-30 so early in the year that the round number barely registered. For the tier above, see our full list of the six-member 40-40 club.

Why the 30-30 club matters

A 30-30 season is proof a hitter helps a team in two separate ways. Power drives in runs; speed creates them on the bases and pressures defenses. Finding both in one player is rare enough that the combination has always drawn attention, even though neither number alone would lead the league.

The stolen-base half is the harder one to sustain. Home run totals have climbed across the sport for decades, but steals fell out of fashion in the 2000s and 2010s as teams worried about the risk of running into outs. Rule changes in 2023, bigger bases and limits on pickoff attempts, brought stealing back, which is a big reason the 30-30 club has filled up so quickly since. Where you land on power-only or speed-only greats shows up in the all-time home run leaders and the all-time stolen base leaders, two lists that rarely feature the same names.

How to read the 30-30 record across eras

Comparing a 1922 season to a 2024 one is not clean. Williams played a 154-game schedule and a dead-ball-adjacent game where 39 homers was staggering; today’s players get 162 games and a livelier ball. On the other side, modern base-stealing was suppressed for years by strategy before the 2023 rule tweaks revived it. The 30-30 line is the same, but the surrounding conditions that make each half hard have shifted repeatedly.

None of that dulls the achievement. It still takes a genuine two-way threat to reach it, which is why the club stays small relative to the number of players who clear 30 home runs alone every year.
