Rain washes out play at ATP's National Bank Open in Montreal

MONTREAL -- Rain washed out all play Friday in the National Bank Open as remnants of tropical storm Debby rolled through.

Thirteen matches were postponed, including three second-round singles matches that were delayed Thursday night. The ATP Tour event is set to run through Monday.

On Thursday afternoon, top-ranked Jannik Sinner opened his title defense with a 6-2, 6-4 victory over Borna Coric in the second round.

Sinner missed the Olympics because of tonsillitis after a quarterfinal loss to Daniil Medvedev at Wimbledon. In January, Sinner beat Medvedev in the Australian Open final for his first Grand Slam title.
