Though all the players on the Los Angeles Dodger roster will be wearing No. 42 on April 15 to commemorate the anniversary of Jackie Robinson breaking Major League Baseball's color barrier, Dodger second-baseman Jeff Kent told reporters yesterday that he will wear the much-celebrated number to honor Yankee great and future Hall of Famer Mariano Rivera. 'Mariano is easily my favorite pitcher, and I think it's wonderful that I finally have the opportunity to show how much he has meant to both me and to the game of baseball,' said Kent, adding that Rivera is 'the greatest player to ever don the No. 42 jersey.' 'Most important, he made it possible for Panamanians everywhere not to be afraid to chase their dreams.' Kent added that he hoped Major League Baseball would eventually 'get their act together' and retire No. 42 for good, which he feels would be the ultimate tribute to Rivera.
