You knew Tiger Woods' wallet took a hit in the wake of his marital problems, but now you can put an exact number on it: $22 million.
The superstar golfer's estimated endorsements for 2010 are worth $22 million less than last year, according to a study by Sports Illustrated, which looked at the 50 highest-earning American athletes.
Woods is still No. 1 on the list, as he has been for the rankings' seven years. But his estimated total earnings of more than $90 million are down from 30 percent from nearly $128 million two years ago. Most of the decline is in lost endorsements.
Golf rival Phil Mickelson is again No. 2 with total earnings of more than $61 million. His estimated endorsement income is $52 million, compared with $70 million for Woods.
