Let's start:
Paula Creamer 
Golf
$6 million
Cramer's victory in the 2005 Sybase Classic made her, at 18, the youngest LPGA event winner in 53 years. She's signed on with Adidas, NEC and Taylor Made. Whenever I hear/read "youngest", I just nod my head. Yet considering she already has won a tournament, a few more wins, and more publicity, she'll move up to the list in a year or so. Haha.

Ana IvanovicTennis
$6.5 million
The 20-year-old Serb has shot up to No. 1 in the world after winning the 2008 French Open. She counts Adidas, Yonex (rackets) and Juice Plus among her major endorsements. Ahhhna. Add Rolex and Verano Motors to her endorsement deals, having heard she got a really pricey deal with Yonex. I think they're prepping Ana to tennis publicity stardom. Yeah she got the killer forehand, another Grand Slam or so would attract even more endorsers (and money). I just hope she has a good agent, and work more for the money just to beat the top-earning female in this list who's really spending a lot of time off-court doing photoshoots and so (sooo un-tennis mentality).
Danica PatrickAuto Racing
$7 million
Patrick's Indy series win in April should set her up for more riches to come, provided she avoids becoming a one-hit wonder. Racing. Wow. Just, wow. More patches sewn into her suit and she'll be on her way to more than $7 million. Too bad you can't see the racers while they're racing because of the helmet. If there were transparent helmets with the same safety quality (it would be interesting), racers would have more endorsement deals.
Lorena OchoaGolf
$10 million
Six tournament wins so far this year have netted Ochoa $1.8 million in prize money to go along with major endorsement deals with Audi and Lacoste. Do you ever wonder why golfers and tennis players are the ones raking in money from endorsement deals? It's because they do not have uniforms. They could wear whatever they want on court/field/course/whatever. So if you want to have a lot of endorsements, play golf or tennis.
Annika Sorenstam 
Golf
$11 million
The Swede has racked up more career prize money than any female golfer in history--some $22 million. The eight-time player of the year has 72 LPGA tournament wins to her credit, including 10 majors. Sorenstam has announced she'll retire from the tour after the ADT Championship in November, just after she turns 38.

Wow, she's dang amazing!
She'll retire. Then she can go back and win again. Ahhh, the beauty of golf.
Michelle WieGolf
$12 million
A limited schedule this year (injuries, college enrollment) didn't hurt Wie's endorsement career. But if the teen sensation wants to extend her deals with Nike and Sony, she'll need to spend more time on the course in 2009. College enrollment. I am proud of Michelle Wie, she was accepted in Stanford, and unlike tennis players, she decided to study. She got kicked out in her latest tourney because she forgot to sign her scorecard, wtfreak?! The thing with golf is that even if you're already uhmm, over the calendar (31++) you can still play competitively and win. Unlike in tennis wherein the career lifespan is relatively short. Boohoo.
Justine Henin

Tennis
$12.5 million
After ringing up $5 million in prize money during a white-hot 2007, Henin walked away from the sport this past spring, just before her 26th birthday. I think I almost cried when I found out she (world number 1) retired just like that. Just like that.. Considering her competition, I think Justine is/was the best female tennis player. I really hope one day she bumps her head (metaphorically) and realizes she wants to play tennis again. Justine Henin is soo great (not just good) a player I think the WTA lost a really important icon. And she's not into off-court stuffs, considering her not-so-many deals. She's really a tennis player, not a businesswoman (unlike what the top-earning athlete in this list said, "I'm a businesswoman." Yeah right).
Venus WilliamsTennis
$13 million
Big sister Venus defeated Serena at this year's Wimbledon final, showing she's got plenty left in the tank. She's parlayed success on the court into her own fashion line, EleVen, a collection of casual and performance footwear and apparel. Having won Wimbledon for 5 times already, her confidence would probably be sky-high coming in to the Olympics. I still love the shorts from EleVen, too bad they are only sold in Steve and Barry's. And she graduated with honors. (She graduated which is not common in tennis life.)
Serena WilliamsTennis
$14 million
The younger of the storied Williams sisters, Serena has bounced back with a vengeance with three tournament wins this year, matching her combined total from 2005 to 2007. Her endorsement stable includes Hewlett-Packard, Nike and Kraft.
She's on a good year for tennis, despite having injuries this year. I love it when Serena gets pissed off in a match, and in interviews. She makes interviews really interesting. Bitching off and the likes. Haha. One thing annoying with the Williams sisters is that they do not play for some time, then when they compete again, they win. Soo unfair! It's like they can just get in and out of the field anytime they want. And what's more annoying is that they CAN actually do it. Haha.
Maria SharapovaTennis
$26 million
There's nothing like the combination of talent and good looks to woo corporations looking to spend endorsement dollars. Sharapova's Australian Open title this year was her third Grand Slam win, along with 16 other singles titles. She's recently added Sony to an endorsement portfolio that includes Pepsi, Colgate-Palmolive, Nike and Motorola. She's so effing rich and celebrated she won awards she didn't deserve. Example: ESPY award. She had the worst year in 2007 yet she still won it. That's plain injustice. She's just celebrated and romanticized so much and I think Anna Kournikova (all looks and minimal tennis skills) was behind this. Kournikova hyped the media about Russian players and tadah Sharapova was next in line. Maybe Russians have plans on dominating the world. Hmm..
MORAL: Wow, right? Throw your school books away and grab a club or a racquet! These freaks of nature (aka athletes) are filthy rich. Imagine how their parents have influenced them with the sports they are excelling in now, when they were still bottle-feeders. Surely, they didn't decide to do tennis or golf all the way back in the days they still don't know how to tie their shoelaces. Most often than not (I can only support my words with tennis sources, not with golfers) their parents are with them during tournaments. Tennis players have tournaments scheduled every week, and their parents are seated in their boxes whenever they play (even if the tournament is not that "bigtime"). They usually act as the coach. Get a life.
