Spain's Paula Badosa reached her first Grand Slam quarter-final on Sunday by defeating Marketa Vondrousova of the Czech Republic in three sets. Badosa, the 33rd seed, saw off the 2019 runner-up 6-4, 3-6, 6-2 and will take on Tamara Zidansek of Slovenia for a place in the semi-finals. The 23-year-old, a former junior champion at Roland Garros, is this season's best performing clay court player. She now has 17 wins against just two losses on the surface, a run which includes the Belgrade clay court title on the eve of the French Open. dj/mw
