DOHA, Qatar -- An emotional Serena Williams returned to the top of women's tennis, overcoming a series of potentially career-ending injuries since 2010 to become the oldest woman to hold the No. 1 ranking.
The 31-year-old Williams rallied from 4-1 down in the third to beat former Wimbledon champion Petra Kvitova 3-6, 6-3, 7-5 in the quarterfinals of the Qatar Open on Friday. She needed to reach the semifinals to replace Victoria Azarenka at No. 1 when the rankings come out next week.
Williams held up one finger after clinching the match with an ace and wiped away the tears as she addressed the cheering crowd.
