Andy Murray staged a stunning comeback against Yoshihito Nishioka in the US Open first round on his long-awaited return to Grand Slam singles tennis.

The 33-year-old came from two sets and a break down against the Japanese to win 4-6 4-6 7-6 (7-5) 7-6 (7-4) 6-4.

The Briton, whose last major singles match was at the 2019 Australian Open before career-saving hip surgery, started flat and dispirited.

But he found his fight and saved a match point to set up an epic win.

The Scot, who eventually claimed victory in four hours 38 minutes, will face Canadian 15th seed Felix Auger-Aliassime in the second round.

British number ones Johanna Konta and Dan Evans both claimed straight-sets victories in their opening matches at the US Open.

Ninth seed Konta, 29, overcame a tough first set to beat compatriot Heather Watson 7-6 (9-7) 6-1.

Evans, 30, the 23rd seed, made light work of Brazil's Thiago Seyboth Wild as he won 6-2 6-1 7-6 (7-5).

The pair join fellow Brits Cameron Norrie, Kyle Edmund and Andy Murray in the second round.

Konta, a quarter-finalist in 2019 at Flushing Meadows, now plays Romania's world number 77 Sorana Cirstea.

Evans will play either France's world number 77 Corentin Moutet or Czech world number 67 Jiri Vesely in the second round.

Former world number six Carla Suarez Navarro has been diagnosed with a rare form of blood cancer.

The Spaniard, who turns 32 on Thursday, has revealed she has early stage Hodgkin Lymphoma and will require six months of chemotherapy.

Suarez Navarro had intended to make 2020 her last season on tour and pulled out of the US Open last week.

She last played in February at the Qatar Total Open, where she claimed one of her two tour titles in 2016.

The seven-time Grand Slam quarter-finalist reached number six in February 2016 and is currently ranked 71 in the world.

Let's have a look back at today's headlines from the tennis world.

Serena Williams says: "I was really happy with how I fought for every point. No matter how I was playing I just had to get my Serena focus back so that was what I was working on today.

"It felt good. Just be Serena and close it out. I know I can do that.

"It's quiet. It's such a good stadium. It's a Grand Slam and I think I'm still as passionate and intense out there.

"I love my job. I love what I do. You can't do it forever even though I've kind of been doing it just over forever. One of these days it's going to end and I love being out here."

It looks routine for Serena Williams but it was even easier for seventh seed Madison Keys, who destroyed Hungary's Timea Babos 6-1 6-1 in under an hour.

Another game for Serena and after only one hour 20 minutes, she is one game away from victory.

Serena knows the race is almost over and a first win will settle her into the tournament.

Kristie Ahn has twice started sets well against fellow American Serena Williams - and twice quickly been pegged back.

Williams took the opening set 7-5 and has won four games on the bounce to take charge of the second set.

Serena Williams fought back from 2-0 down in the opening set against Kristie Ahn and it has been a similar start in the second set on Arthur Ashe Stadium.

Evans will play either France's world number 77 Corentin Moutet or Czech world number 67 Jiri Vesely in the second round.

Evans only faced two break points in that match - both late in the first set.

He kept his unforced errors down to 13, a very solid performance overall.

Serena Williams is bidding for her 24th Grand Slam title to match Margaret Court's record and has taken her first set of the tournament.

She was broken in the very first game of the match against fellow American Kristie Ahn, who led 2-0 but Williams fought back and then broke Ahn's serve again in the 12th game to win set one by a 7-5 margin.

That win means there will be FOUR British men in the second round: Dan Evans, Andy Murray, Cameron Norrie and Kyle Edmund.

It's the first time that's happened at the US Open since 1974.

Seyboth Wild saves the first match point with an unreturnable serve down the middle.

Ok NOW it's match point.

Beautiful passing shot from Evans.

Another backhand into the net from Seyboth Wild puts Evans in control. At 5-3, he's two points from victory.

The British number one lets out a frustrated cry as his forehand flies into the net. No match point yet...
