PARIS: Sania Mirza and her Czech partner Lucie Hradecka displayed fearless brand of tennis but much younger and superior American singles players Coco Gauff and Jessica Pegula prevailed in the women's doubles third round of the French Open, here on Tuesday. Despite a combined age of 72 years, Mirza and Hradecka produced some high quality tennis but lost 4-6, 3-6 to Pegula, ranked 11th in the singles, and world number 23 Gauff. Mirza was impressive with her lower and angled forehands while Hradecka's power-packed backhand hitting from the baseline was a treat to watch but the Americans got those crucial points that dictated the outcome of the match.
