World number two, Elena Rybakina, survived a huge scare to battle into the Canadian Open quarterfinals on Sunday in Toronto, while fourth-ranked Coco Gauff cruised through. Kazakhstan’s Rybakina recovered from 0-3 and two breaks down in the final set to beat Liudmila Samsonova 6-4, 4-6, 6-4 before American Gauff swept aside Russian teenage qualifier Alina Korneeva, 6-3, 6-1. Rybakina will face four-time Grand Slam champion Naomi Osaka, who eliminated home hero Leylah Fernandez 6-4, 6-4. Osaka broke in the seventh game of each set to advance in 82 minutes. The Japanese star, who has never faced Rybakina, said sound groundstrokes were key.
