U.S. Open champion Emma Raducanu's French Open debut was difficult for more than a set before she emerged with a 6-7 (4), 7-5, 6-1 victory over Czech qualifier Linda Noskova. The 12th-seeded Raducanu came back to win in more than 2 1\/2 hours against a player who was trying to pull off the sort of upset Raducanu did over and over again at Flushing Meadows last year. The 17-year-old Noskova is ranked 184th and was making her Grand Slam debut after going through qualifying.
