Every MLB team's retired numbers originally appeared on NBC Sports Chicago

One of the most iconic moments in professional sports is having your number retired.

While MLB has seen numerous legendary players have their numbers retired, the league has only had one number retired throughout.

So, who is the player that reached that remarkable milestone and what are the retired numbers for each MLB team? Here we do a deep dive:

Is 42 the only number retired in baseball? 

The MLB retired Jackie Robinson's number (42) on April 15, 1997.

Robinson's number remains the only one to be retired across the league.

What is Jackie Robinson Day?

Every year on April 15, the league recognizes the former Dodgers second baseman on Jackie Robinson Day.

The celebration is an honor of Robinson's major league debut in 1947 and is celebrated by all players, coaches, managers and umpires wearing No. 42. 

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.
