Barbora Krejcikova reached her first Grand Slam quarter-final at the French Open on Monday with a straight sets win over 2018 runner-up and former US Open champion Sloane Stephens. Krejcikova, ranked 33 in the world, defeated the American 6-2, 6-0 to record a ninth successive win on the tour having arrived in Paris on the back of a maiden singles title in Strasbourg. The Czech player, a former doubles champion at Roland Garros, will face either Coco Gauff of the United States or Tunisia's Ons Jabeur for a place in the semi-finals. dj/mw
