MONTREAL (AP) — Top-ranked Jannik Sinner opened his National Bank Open title defense with a 6-2, 6-4 victory over Borna Coric on Thursday in the second round of the National Bank Open.
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.
"Very happy and excited to go back on court," Sinner said. "It was a tough match, but I served quite well in important moments and returned well in the games when I broke him. So a very positive start."
Second-seeded Alexander Zverev routed Jordan Thompson 6-1, 6-1 for his ATP Tour-leading 48th match victory of the year.
The night session was delayed by rain.
