You seriously have to hand it to Serena Williams. This year alone, she has managed to rack up a staggering $12.6 million in prizes from beating her opponents on the tennis court.

As Al Jazeera reports:
Worryingly for her flagging rivals, she now boasts a record of winning 32 of her last 34 matches against top five players.

Furthermore, Sunday's triumph may just persuade Williams that adding to her 17 Grand Slam titles during 2014 is certainly possible, and that winning another six, to overhaul Steffi Graf, might eventually come within reach too.

But Williams declined to say whether or not 2013 was her best year.

"I live to win Slams," she said.

"I am excited to win the WTA Championships, but I would say (this season is) only top three.

"I am not going to say that this is the best. I think some years I can do better and next year, I hope — I look forward to it."
Something tells us that Serena is definitely serious when she says she thinks her best years are still to come.
