In total , 29 players have reached the 50 home run club in MLB history and nine have done so more than once . Of these , seventeen were right - handed batters , eleven were left - handed , and one was a switch hitter , meaning he could bat from either side of the plate . Four of these players ( including two active members of the 50 home run club ) have played for only one major league team . The New York Yankees are the only franchise to have five players reach the milestone while on their roster : Ruth , Mickey Mantle , Roger Maris , Alex Rodriguez , and Aaron Judge . Ten players are also members of the 500 home run club and two of them ( Willie Mays and Rodriguez ) are also members of the 3,000 hit club . Ten players won the Most Valuable Player ( MVP ) Award in the same year as their 50 home run season . Mantle is the only player to have earned the Major League Triple Crown alongside achieving 50 home runs , leading both leagues in batting average , home runs and runs batted in ( RBI ) . Mantle and Maris -- collectively known as the M&M Boys -- are the only teammates to reach the 50 home run club in the same season , hitting a combined 115 home runs in 1961 and breaking the single - season record for home runs by a pair of teammates . Albert Belle is the only player to amass 50 or more doubles in addition to attaining 50 home runs . Prince Fielder , at 23 years and 139 days , was the youngest player to reach the milestone while Bonds , at age 37 , was the oldest .
