1. Floyd Mayweather Jr.
fortunate 50 floyd mayweather
Occupation: Boxer
Salary/Winnings: $90,000,000
Endorsements: 0
Total: $90,000,000

The May 4 welterweight title bout with Robert Guerrero brought Mayweather a guaranteed purse of $32 million, with his pay-per-view cut yielding at least another $13 million. Once he gets a similar payday for his Sept. 14 fight, likely against Saul (Canelo) Alvarez, he should hit $90 million in 2013 earnings. From two matches alone Mayweather, 36, stands to make nearly as much as Tigers pitcher Justin Verlander will from his five-year, $140 million extension.

The Fortunate 50 measures salary, winnings, bonuses and endorsements based on consulting players' associations, tour records, online databases, agents and media reports. The endorsement estimates come from a stable of marketing executives, agents, and other experts. Candidates for the Fortunate 50 must be U.S. citizens or play in a U.S.-based league. Endorsements reflect current deals, and salaries are based on current or most recently completed seasons (e.g., NFL salaries come from the season that ended in February). For auto racing and tennis, prize money came from the 2012 calendar year. Golf earnings are from July 1, 2012 through April 21, 2013. Boxing purses are from August 2012 through May 2013 (but projected money from bouts scheduled through September were included).
