MLBPA commissioner Bart Starr has announced his resignation from the game’s governing body.
He was a four-time All-Star and two-time World Series champion, and was named the National League’s commissioner in February.
His successor, Mark Rodgers, is the first MLB executive to lead the league since the 1976-77 season.
“This is a difficult time for the MLBPA, the game, and for all baseball fans,” Starr said in a statement released by the league.
“I appreciate the time and efforts you have put into building this organization over the years, and I am proud of the work you have done to build a better, more inclusive game and a stronger fan experience for fans all over the world.”
Rodgers is the second MLB executive since the 2017 season to lead MLB.
In January, he led the league’s player safety and concussions committee.
He said in the statement that he is “confident that our collective efforts to achieve lasting, positive change will be sustained as we work together to ensure a better game and more fun to watch.”
