NEW YORK (Reuters) -World number one Jannik Sinner opened his U.S. Open title defence with a 6-1 6-1 6-2 demolition of unseeded Czech Vit Kopriva on Tuesday, appearing to be fit again after illness derailed his Cincinnati finale.
The four-times major winner retired from the U.S. Open tune-up tournament earlier this month due to sickness but had no issues at Arthur Ashe Stadium as he sent over seven aces.
