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 .
Foods high in amino acids may also bump up HGH production in your body. Your basic protein-packed meats (such as chicken, beef, pork, and fish) are good places to start, and dairy products (such as milk, cheese, and yogurt) can also provide the nutrition you need to encourage HGH secretion. A 2008 study published in the Journal of the International Society of Sports Nutrition reported that choline, a neurotransmitter, may boost production of growth hormone, so be sure to add foods that are high in choline, such as eggs and shrimp, to your training table.
