San Francisco Frontiers - Sinner repels Shapovalov to reach US Open last 16

World number one Sinner rallied from a set down to beat Shapovalov 5-7, 6-4, 6-3, 6-3 and keep alive his bid to become the first man to retain the title in New York since Roger Federer in 2008.

"A very, very tough match today. I've known Denis for quite a long time. I knew that I had to play at a very high level," said Sinner, who lost his previous meeting with Shapovalov at the 2021 Australian Open.

Sinner awaits the winner of the evening session match between US 14th seed Tommy Paul and Alexander Bublik, the 23rd seed from Kazakhstan.

"Week two is completely different. It's always a great sight that I'm still here. It's getting tougher and tougher, also physically and mentally," said Sinner.

The Italian made serene progress through the first two rounds but dropped his first set of the tournament against a resurgent Shapovalov, a former top-10 player whose career was stalled by injury.

A US Open quarter-finalist in 2020, Shapovalov signalled his intent with a break in the fourth game and raced 5-2 ahead in the first set.

Sinner broke to get back on serve but Shapovalov produced a gutsy hold, saving a break point for 6-5 before taking the next game and the set.

Top seed Sinner punished a slack service game from Shapovalov at 3-3 in the second set as he dragged himself back into the match at a set apiece.

Shapovalov responded by breaking early in the third set and surging into a 3-0 lead, but he couldn't sustain his level and a defiant Sinner hit back by winning nine games on the spin.

The Canadian offered some belated resistance but by then it was too late as Sinner sealed his 24th successive Grand Slam match win on hard courts.

Sinner has reached the final of all three Grand Slams this season, winning the Australian Open and Wimbledon either side of a defeat to Carlos Alcaraz at the French Open.

Federer is the last man to successfully defend the US Open, winning the title each year from 2004-08.
