Alex Rodriguez is widely considered one of the greatest baseball players of all time. Known as "A-Rod," he was the youngest player ever to reach the 500 career home run milestone and is a prestigious three-time American League MVP (2003, 2005, and 2007). He broke into the Major Leagues with the Seattle Mariners in 1994 at just 18 years old, spending seven seasons in Seattle before his record-breaking tenures with the Texas Rangers and New York Yankees.
