Greece's Maria Sakkari demolished last year's French Open runner-up Sofia Kenin 6-1, 6-3 on Monday to reach the quarter-finals of a Grand Slam for the first time. The world number 18 needed just 68 minutes to defeat the fourth-seeded American and set up a clash with either reigning champion Iga Swiatek or Ukrainian teenager Marta Kostyuk for a place in the last four. mw/dj
