There was no letdown for Garbine Muguruza in her follow-up match at the French Open after taking down defending champion and World No. 1 Serena Williams.

In her third round match at Roland Garros, the 20-year-old Spanish rising star in women’s tennis easily dispatched Slovakia’s Anna Schmiedlova, who defeated Venus Williams in the second round.

Muguruza, who hit 24 winners in the match, beat Schmiedlova 6-2, 6-4. She won more than 65-percent of the points on her first serve.

She’d previously beaten her Slovak opponent in the second round at this year’s Australian Open.

Muguruza, currently ranked No. 35 in the world, now advances hit to her second successive Grand Slam fourth round appearance, where she’ll face either Pauline Parmentier or Mona Barthel.
