3891. Alexander Emmanuel "Alex" Rodriguez

Alexander Emmanuel "Alex" Rodriguez (born July 27, 1975) is an American professional baseball third baseman with the New York Yankees of Major League Baseball. Known popularly by his nickname A-Rod, he previously played shortstop for the Seattle Mariners and the Texas Rangers.
Rodriguez is considered one of the best all-around baseball players of all time. He is the youngest player ever to hit 500 home runs, breaking the record Jimmie Foxx set in 1939, and the youngest to hit 600, besting Babe Ruth's record by over a year. Rodriguez has fourteen 100-RBI seasons in his career, more than any player in history. On September 24, 2010, Rodriguez hit two home runs, surpassing Sammy Sosa's mark of 609 HRs, and became the all-time leader in home runs by a player of Hispanic descent.
In December 2007, Rodriguez and the Yankees agreed to a 10-year, $275 million contract. This contract was the richest contract in baseball history (breaking his previous record of $252 million).
In February 2009, after previously denying use of performance-enhancing drugs, including during a 2007 interview with Katie Couric on 60 Minutes, Rodriguez admitted to using steroids, saying he used them from 2001 to 2003 when playing for the Texas Rangers due to what he called "an enormous amount of pressure" to perform.

Rodriguez was drafted first overall by the Seattle Mariners in 1993. He was signed by Roger Jongewaard right out of high school. In 1994, Rodriguez played for Seattle's AAA affiliate, the Calgary Cannons. In 32 games, he had 37 hits in 119 at bats for a .311 batting average. He also compiled 6 home runs and 21 runs batted in. Rodriguez rose rapidly through the Mariners organization, and made his major league debut as the starting shortstop on July 8, 1994, in Boston at 18 years, 11 months, and 11 days of age. He was just the third 18-year-old Major League shortstop since 1900. He was also the first 18-year-old Major League player in 10 years, and the youngest position player in Seattle history. His first Major League hit was a single off Sergio Valdez on July 9 at Fenway Park. Rodriguez's first Major League campaign lasted just one month; the season was cut short by the 1994 Major League Baseball strike.
Rodriguez then split most of 1995 between the Mariners and their AAA club, the Tacoma Rainiers. He connected for his first Major League home run off Kansas City's Tom Gordon on June 12. Rodriguez joined the Major League roster permanently in August, and got his first taste of postseason play, albeit in just two at-bats. Again, he was the youngest player in Major League Baseball.
