Following a brief pregame ceremony on August 12, Rodriguez donned the Yankee pinstripes for one final time as a player, contributing an RBI double in the first inning to help his team win. While he never reached the record-shattering heights that once seemed attainable, the slugger still finished with numbers that rank among the best ever in several categories, including home runs (696), RBIs (2,086), hits (3,115) and runs (2,021). Along with his three MVP awards, he won two Gold Gloves for his fielding prowess and was selected for 14 All-Star Games.
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 . 
Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes.
