Top 10 most valuable athletes ranked

#5 Phil Mickelson: $19.6 million (30 % decrease over last year)

Phil Mickelson proving true the old adage that Old is indeed Gold

Winner of 42 PGA titles (Including 5 Majors), Lefty as Phil Mickelson is fondly known, is the oldest athlete on this list at 47 years old. Although facing a sharp drop in brand value year-on-year - corresponding with a drop in performances, his last tournament triumphs came in 2013, where he won one major and one PGA Tour event - he is still formidable enough to make the top 5 list this year as well.

He currently endorses KPMG (no, really, boring ol' KPMG uses athletes for endorsing them in the US!), Rolex (always a big-money deal, that) Exxon Mobil, Workday Inc and Callaway Golf. Interestingly he also endorses the medicine that he says helped him fight arthritis in 2010, Enbrel.
