So long the dominant force in women's tennis, Serena Williams will head to Wimbledon this month in danger of losing her No.1 ranking to Spain's Garbine Muguruza.
Muguruza, beaten by Williams in last year's Wimbledon final, turned the tables to win the French Open on Saturday and climbed to a career-high second on the WTA list.
Should she win the Wimbledon title and the 34-year-old Williams loses before the final, she would rise to number one, a position Williams has held for 178 weeks.
"Everybody's dreaming about being number one," 22-year-old Muguruza said after her straight sets defeat of Williams.
"My focus is just on winning matches and tournaments. But of course I would be very happy to be number one."
