Serena Williams will be 2013's Year-End No. 1, having racked up enough ranking points already to finish the season at the top of the pack.
Serena Williams has been the leading light in the WTA throughout the 2013 season, racking up an astonishing 67-4 match record and picking up slam titles at Roland Garros and the US Open. To add to this, she also won Premier tier titles in Brisbane, Miami, Charleston, Madrid, Rome and Toronto, as well as her first International tier title in Bastad. As a result of her exploits, the American is guaranteed to finish the season as the World No. 1. She also achieved this feat in 2002 and 2009.
"Serena has proven time and time again throughout her career that she is an incredible champion, both on and off the court," said WTA Chairman and CEO Stacey Allaster. "This season she continues to rewrite the record books, proving she is one of the sport's greatest athletes of all time."
Serena is currently the oldest player to ever hold the No. 1 spot. To add to this, her prize money total for 2013 is already at a record-breaking level. Having picked up a record $3.6million payout at the US Open, she took her prize money total for the year to $9,077,322. This is well in advance of the $7,923,920 record set by Victoria Azarenka in 2012.
Williams is now the seventh player since the introduction of the computerised rankings to finish the season as the World No. 1 three or more times. She will be presented with the Year-End No. 1 trophy during an on-court ceremony in late-October at the WTA Championships in Istanbul.
