Nobody is ever surprised when they hear athletes like Tiger Woods or Peyton Manning are among the highest-paid in their sport.
However, in an era with skyrocketing salaries there are also some athletes who are not superstars who have also made a ton of money in their careers.
Most of these athletes are not household names, and yet their career earnings rank them close to their superstar teammates and rivals. Others are superstars or were at one point and yet the surprise is just the sheer amount of money they have been paid in their career.
Here are 21 of the biggest surprises.
Cristie Kerr — $15.9 Million
Sport: Golf

But Kerr, who has won two majors in her career, has the advantage of longevity, having played her first season on the LPGA Tour in 1997. She has won 16 tournaments in her career.
Caroline Wozniacki — $18.3 Million
Sport: Tennis
All-time rank (within sport): No. 11

David Ferrer — $24.0 Million
Sport: Tennis
All-time rank (within sport): No. 9
2014 Earnings: $2.1 million
Career highlights: Ferrer has had a healthy career despite never winning a Grand Slam title and having played his career in the shadows as arguably the fifth best player in the "Big 4" era of men's tennis (Roger Federer, Rafael Nadal, Novak Djokovic, Andy Murray).
