On February 15, 2004, the Rangers traded Rodriguez to the New York Yankees for second baseman Alfonso Soriano and a player to be named later ( Joaquín Árias was sent to the Rangers on March 24). The Rangers also agreed to pay $67 million of the $179 million left on Rodriguez's contract. Rodriguez agreed to switch positions from shortstop to third base, paving the way for the trade, because the popular Derek Jeter was already entrenched at shortstop. Rodriguez also had to switch uniform numbers, from 3 to 13; he had worn 3 his entire career, but that number is retired by the Yankees in honor of Babe Ruth . This was only the second time in MLB history that a reigning MVP was traded, with the first coming in 1914 when Eddie Collins was traded to the Chicago White Sox from the Philadelphia Athletics for cash considerations.
