Yes, all players and coaches wear the uniform number of 42 on Jackie Robinson Day.
Mariano Rivera is the only active player to wear number 42.
April 15 of every year
Only Mariano Rivera is the only person utilizing that number.
it was Jackie Robinson day
The only active baseball player to wear the number 42 is Mariano Rivera of The Yankees. On April 15 1997, it was decided that to honor Jackie Robinson, the number 42 would be retired throughout baseball. Players who wore the number at the time were grandfathered in, and Mariano Rivera is the last player remaining from that time.
In the 2009 MLB season, only Mariano Rivera of the New York Yankees wears #42.
The number 42 was worn by Jackie Robinson and is retired throughout major league baseball. Only older players, such as Mariano Rivera on the Yankees still wear the number 42 since they wore it before it was retired. This year however for some reason all blue jays are wearing the number 42... I would like to know why :S
Mariano Rivera is the current player and will be the last player on the Yankees to wear number 42. The number was retired throughout baseball in honor of Jackie Robinson. The players who were wearing that number when it was retired were allowed to keep it.
MLB permanently retired the #42 in 1997. However, they allowed anyone who was wearing #42 at the time to continue to wear it. Mariano Rivera of the Yankees is the only player wearing #42 currently as he was in MLB at the time of its retirement. Once he retires, no one will ever again wear the #42 in MLB.
