Diallo last Canadian standing in U.S. Open singles

Five Canadians hit the court at the U.S. Open on Tuesday.

Bianca Andreescu, the 2019 U.S. Open champion, was knocked out in the first round Tuesday.

Only 22-year-old Gabriel Diallo of Montreal will play another day.

Diallo opened the evening session with a four-set win over Jaume Munar: 6-4, 3-6, 6-3, 7-5. The Canadian recorded 20 aces.

However, Mississauga’s Bianca Andreescu, the 2019 champion, lost an evening session heartbreaker to fifth-seeded Jasmine Paolini, a French Open and Wimbledon finalist this summer. Andreescu took the first set 7-6 (5) in 80 minutes, but Paolini bounced back 6-2, 6-4 to eliminate the Canadian in two hours, 48 minutes.
