Robinson is best known for breaking the color barrier in baseball.
What is the most retired number in the MLB?
No. 20 has been retired by 11 teams, more than any other number.
After that, it’s No. 14 at 10 times.
What is the rarest number in MLB?
Ahead of the 2020 MLB season, Nos. 86, 89 and 92 had never been worn, according to Baseball Reference.
In August 2020, the Cardinals checked those two numbers off the list with reliever Génesis Cabrera taking No. 92 and reliever Jesus Cruz wearing No. 86.
Finally, No. 89 was worn on the last day of August 2021 with Yankees pitcher Miguel Yajure wearing it, marking the date every number had appeared on a big league diamond.
