Muguruza eases into last 16 as Sharapova, Serena edge closer to reunion

Former champion Garbine Muguruza reached the French Open last 16 on Saturday with a comfortable 6-0, 6-2 win over Australia's Sam Stosur as Serena Williams and Maria Sharapova stood one win away from renewing their longtime rivalry.

Spanish third seed Muguruza, the 2016 winner in Paris and the reigning Wimbledon champion, fired 15 winners past Stosur, the 34-year-old 2010 runner-up and former US Open champion.

After wrapping up the first set in just 25 minutes, Stosur only got on the board in the third game of the second.

"I knew this would be very tough against a former US Open winner and a player who has made the final here," said 24-year-old Muguruza.

"If I didn't play my best tennis, I realised that it would be very hard.

"Coming back here to Court Philippe Chatrier where I won two years ago always brings special feelings inside me." The Spaniard goes on to face Lesia Tsurenko of Ukraine
