Pete Rose's MLB playing career ended in 1986, but his legacy in the sport began to change three years later.
On this day in 1989, Major League Baseball commissioner Peter Ueberroth announced the league was investigating Rose for unspecified "serious allegations." The next day, Sports Illustrated reported on Rose's ties to gambling on baseball.
At the time, Rose was the manager of the Cincinnati Reds. He was a player-manager with the team starting in 1984, but became the outright manager of the team following his retirement as a player in 1986.
The investigation came as a surprise after Rose's illustrious baseball career.
