More than 200 players will wear Jackie Robinson?s No. 42 retired by baseball 10 years ago in ballparks across the country on Sunday, the anniversary of Robinson?s first appearance with the Brooklyn Dodgers in 1947. Willie Randolph said he once borrowed a biography on Robinson from a library and ?I saw how one life can make such a tremendous impact.? While the tribute has received baseball?s approval, it grew spontaneously from a request by the Reds? Ken Griffey Jr., who asked Commissioner Bud Selig earlier this month if he could wear the number on April 15. What has evolved since is surprisingly organic for a group of famous, feted athletes with multimillion-dollar contracts. As word of Griffey?s gesture spread, small groups of players ? among them stars like Barry Bonds, Dontrelle Willis and Gary Sheffield ? decided also to wear 42 that day. Soon, there was a representative from every team. The Los Angeles Dodgers then decided to have their entire roster wear 42. Now, there are six major league teams that plan to have everyone in uniform wearing No. 42 ? players, coaches, manager and bat boys. Those teams are the Dodgers, the Cardinals, the Pirates, the Phillies, the Brewers and the Astros. And the number of jerseys having a new 42 sewn onto the back remains fluid, but seems to be increasing by the day.
