Jannik Sinner off to a flyer at Canadian Open after Paris Olympic withdrawal

Italian Sinner had missed the Paris Olympics with tonsillitis, but showed no signs of any lingering issues as he coasted to a 6-2 6-4 win over Croatian Coric in just over an hour and a half.

Australian Open champion Sinner - who paired up with British number one Jack Draper in the doubles, making it through to the quarter-finals - will face Alejandro Tabilo in the third round after the Chilean later beat Lorenzo Sonego 6-4 6-2.

Elsewhere on Thursday, Russian world number five Daniil Medvedev suffered an early exit after a surprise defeat to Alejandro Davidovich Fokina, the Spaniard coming through in three sets 6-4 1-6 6-2.

Kei Nishikori earned his first top 20 win since 2021 after he upset world number 11 Stefanos Tsitsipas 6-4 6-4.

American qualifier Brandon Nakashima completed a 6-2 6-7 (5) 6-1 win over countryman Tommy Paul, who missed the chance to close up on Tsitsipas in the Race To Turin.

World number four Alexander Zverev comfortably saw off Australian Jordan Thompson 6-1 6-1 to reach the third round, while Casper Ruud, Holger Rune, Andrey Rublev and Grigor Dimitrov also progressed.

Meanwhile, Olympic champion Novak Djokovic has withdrawn from next week's Cincinnati Open, the tournament has announced.

The Serbian, who won the event last year, has been managing a torn meniscus in his right knee, which needed surgery ahead of Wimbledon.

Cincinnati Open tournament director Bob Moran said in a statement: "We certainly understand that it is a quick turnaround from his Olympic triumph to come to Cincinnati.

"His title run here last year was so memorable. We are eager to see him on court again soon."

In the women's game, British number one Katie Boulter will face Aryna Sabalenka in the third round of the National Bank Open in Toronto after Beatriz Haddad Maia was forced to retire with a back problem.

Brazilian Haddad Maia had come through a marathon first-round match against Marie Bouzkova - which lasted three hours and 20 minutes - but was soon calling for the trainer after the opening game against Boulter.

The world number 33 received lengthy treatment on her lower back and although she tried to resume, Haddad Maia swiftly conceded after Boulter levelled the set at 1-1.

Number two seed Sabalenka kicked off her campaign with a 6-2 6-2 win over China's Yuan Yue, having missed Wimbledon and the Olympics with a shoulder injury.

Elsewhere on Thursday, top seed Coco Gauff comfortably beat Wang Yafan 6-4 6-4 in her second-round match.
