Floyd Mayweather Jr.

For the second straight year, welterweight champion Floyd Mayweather Jr. is the highest paid athlete, according to a recent report by Sports Illustrated. Mayweather Jr. is poised to make $90 million this year as long as his Sept. 14 fight, likely against Saul Alvarez, happens as scheduled. If this is the case, Mayweather Jr. will only need to fight twice in 2013 to earn his huge paycheck. Mayweather Jr. beat Robert Guerrero on May 4.
