St. Louis Cardinals' Aledmys Diaz takes practice on the field before the start of an exhibition spring training baseball game against the Detroit Tigers, Monday, March 10, 2014, in Jupiter, Fla. Diaz reported to spring training Monday after the Cardinals signed the Cuban free agent shortstop to a major league contract. The Cardinals were among a number of teams, including the Yankees, who held private workouts for the right-handed hitting Diaz and the deal is believed to be for $15-20 million for four years.
