PARIS — Coco Gauff’s grand slam glory will have to wait. The 17-year-old Gauff let the first set slip away, then let her emotions get the best of her in a frustrating start to the second in a 7-6 (6), 6-3 quarterfinals defeat at the French Open on Wednesday to unseeded Barbora Krejcikova. Gauff led 3-0 at the outset, then 5-3, and held a total of five set points in the opener, but failed to convert any. Krejcikova took advantage, grabbing that set by taking the last four points of the tiebreaker. She then reeled off 15 consecutive points during one stretch en route to a 5-0 edge in the second set. #CocoGauff #FrenchOpen #Tennis The New York Post is your source for breaking news, news about New York, sports, business, entertainment, opinion, real estate, culture, fashion, and more.
