Alex Rodriguez: Love him or hate him, there's no denying the immense amount of talent and success this man possesses.
He signed the biggest contract ever when he latched on to the Texas Rangers in 2001.
Since the turn of the decade, A-Rod has led the league in home runs in five different seasons, and in RBI twice. He was named AL MVP three times, and was named to the All-Star Game in every season except 2009.
Of course, Rodriguez came up as a shortstop with the Mariners. But when he came over to the Yankees, he had to move to third base because some guy named Jeter was occupying short.
But that has not stopped A-Rod from being the most feared hitter of the decade.
For the decade: 435 homers, 1,243 RBI, and batting average/on-base/slugging of .304/.401/.587! And now he's even got a World Series ring.
All of this success, and he won't even be 35 until July 2010!
