Which made Canseco’s second benefactor — Mike Wallace — all the more important. John Hamlin, a producer at 60 Minutes , had gotten a tip about Canseco’s book from a friend at another network. (The friend couldn’t act on it because his employer was a Major League Baseball rights holder.) Hamlin began calling baseball people and confirming the details. Almost no one would talk on the record, but they suggested that Canseco’s account was true. One of the few allegations Hamlin couldn’t verify was Canseco’s insistence that Roger Clemens was juicing.
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 sold or traded, with the first coming in 1914 when Eddie Collins was sold to the Chicago White Sox from the Philadelphia Athletics .
