Serena Williams has clinched the year-end No. 1 ranking for the third time in her career, according to the WTA Tour.
Williams, who turned 32 on Thursday, is 67-4 this year with a career-high nine titles and a record $9.1 million in earnings. She won her first French Open since 2002 and defended her title at the U.S. Open earlier this month. Williams had a 34-match winning streak before losing to Sabine Lisicki in the fourth round of Wimbledon.
In February, Williams recaptured the No. 1 ranking for the first time since 2010 and became the oldest woman to hold the top spot since the computer rankings were introduced in 1975.
Williams will be presented with the year-end No. 1 trophy during the WTA Championships next month in Istanbul. She also finished the year at No. 1 in 2002 and 2009. The 17-time Grand Slam champion is the seventh player to earn the distinction at least three times, joining Steffi Graf, Martina Navratilova, Chris Evert, Lindsay Davenport, Justine Henin and Martina Hingis.
