Twins outfielder/designated hitter Rondell White is leaning toward retiring at the end of the season, which would end a 15-year career. White said injuries over the past few seasons are a strong signal that he may no longer be able to handle the physical demands of the game. After training throughout the offseason, White tore a calf muscle the first week of the 2007 season, knocking him out of 95 games.
