NEW YORK : Jannik Sinner normally employs his powerful serve, on-court speed and rocket forehand to dispatch opponents, but the world No.
1 said the "mental part" of his game was especially important in his run to the U.S. Open title this year.News of two failed doping tests broke just days ahead of the year's final major, and although Sinner was cleared of wrongdoing by an independent tribunal, the saga threatened to tarnish a dream season that saw him claim five titles, including his first major at the Australian Open."I understood, especially in this tournament, how important the mental part is in this sport," Sinner said in an on-court interview after his 135-minute 6-3 6-4 7-5 victory over 12th seed Taylor Fritz on Sunday.The 23-year-old became the first Italian man to claim a U.S.
Open singles title and the youngest man to ever win both hard-court Grand Slam titles in a single season with wins in Melbourne and New York.Unsure if he would be welcomed by the Flushing Meadows crowds or jeered after some media and current and former players claimed the world No.
1 received favourable treatment, Sinner said he leaned on family and his training team to help tune out the distractions."The general reaction of the players was quite positive, even when things came out.
