HELENSBURGH wheelchair tennis star Gordon Reid is through to the semi-finals of the wheelchair singles at the Paralympics in Tokyo.

The former Hermitage Academy pupil fought back superbly from 4-0 down in the opening set to defeat Argentinian Gustavo Fernandez 7-5, 3-6, 6-1 in a repeat of his Rio 2016 quarter-final.

Reid, 29, is already assured of a medal in Tokyo after winning through to the men's doubles gold medal match alongside fellow Brit Alfie Hewett.

The victory came on the day that Reid's isolation in his room at the Tokyo athletes' village came to an end – after he initially feared his defence of his Rio singles gold might be over without him hitting a ball.

A member of the Team GB wheelchair tennis support squad tested positive for coronavirus just a day before the opening ceremony, prompting an emoitional phone call home for Reid – and a sleepless night.

He was eventually cleared to play but was forced to follow a strict routine which included only leaving his room for matches and practice and not socialising with team-mates.

After Wednesday's win over Fernandez, Reid said: “This morning was the first time that I could get out and go to the food hall myself and not have it delivered to the room because it’s 10 days since the test.

“I was pretty emotional because at that stage, him testing positive and us being around – not close contacts but still being in similar places for the last few days – was a scare.

“But it’s not been an issue so far so I’ve got no complaints.”

Following Wednesday's tie Reid was asked about the controversy over bathroom breaks after Andy Murray's US Open opponent, Stefanos Tsitsipas, disappeared for almost eight minutes ahead of the fifth set of the pair's tie at Flushing Meadows.

Former world number one Murray said he "lost respect" for his opponent after the incident.

Asked if anything similar might happen in the wheelchair version of the game, Reid said: “I don’t think so. Definitely not in the men’s division anyway, for sure.

“I think everybody has a lot of respect for each other and we play each other at almost every event.

“I don’t know if you’d be able to do that sort of thing and show your face the next time. Thankfully it’s not an issue for us.”
