Australia’s last man standing on the opening day at Wimbledon was barely standing at all by the time he had battled his way into the second round.

Four Aussie men took to the grass but by the time the last Pimm’s had been drained by spectators on the sun-drenched sidelines on Monday (local time) only one was left, and Jordan Thompson’s mood was more akin to a man who’d lost as well.

Wearing a brace to protect a back injury and a grimace as he fought the pain Thompson rallied from two sets down to beat Vit Kopriva 3-6 4-6 6-3 7-6 (7-1) 6-1 in a three-hour, 37-minute roller-coaster in blazing London sunshine.

It was the third year in succession Thompson had come from two sets down in Wimbledon’s opening round, remarkably each time on Court 9.

But despite his triumph the 31-year-old Sydneysider was a morose figure post-match, with the limitations of injury on his play and practice sapping the joy of victory.

Thompson said he might not even be able to get on court on Wednesday for his second-round match with Benjamin Bonzi, shock conqueror of No.9 seed Daniil Medvedev.

“I’m just praying I can get back on the court,” he said. “I’ll do everything I can; live in an ice bath or hyperbaric chamber. I’ll hardly practice.

“I’m taking painkillers, anti-inflammatories, but sometimes they can’t really help.

“I’m just lucky to be on court, even though it is sad that it’s Wimbledon and I am not enjoying it as much as I usually do.

“I love playing tennis, competing, running around. I love getting the balls I probably shouldn’t and I can’t do that at the moment. It’s extremely frustrating to watch balls go past me that I’m not even close to because I can’t move. Practising, warming up, is just putting my body through hell.

“I don’t think anyone would enjoy that.

“I’m not moving well. I’ve had to change the style of my serve, to try and not get into positions that cause discomfort, but that’s easier said than done on a tennis court.

Koprina, a 28-year-old Czech at a career-high 78th in the world, was a tricky opponent for Thompson. The Australian has slid from 26th at the start of the year to 44th as injuries have disrupted his season.

“I have no idea how I [won] that,” he said.

“He was playing well, I just thought ‘five sets, hopefully I’ll get better and better’. I managed to sneak a break in the third, clawed out a tough fourth set and just took momentum.

“I told myself, ‘keep thinking you’ve no chance’. Obviously I still believe I can win but I told myself, ‘forget it, maybe I’ll enjoy it more that way’.”

Thompson might find a smile it if he keeps winning. Medvedev’s exit and Alexei Popyrin’s defeat by Briton Arthur Fery means he cannot meet a higher-ranked player until the second week, which he has never reached at Wimbledon.

But first he will have to crank up his aching body to back up his comeback five-setter, something he failed to do here in 2023 and 2024.

Kasatkina hopes for change of fortune

Australia’s No.1, Daria Kasatkina, is hoping the rejuvenating air of Wimbledon will transform her fortunes after a dismal start to the grass-court season with losses at Berlin, Queen’s Club and Eastbourne.

It’s the grand slams, Kasatkina believes, that still bring the best out of her, just as she managed to be the last Australian standing by reaching the fourth round in the French Open.

The 16th seed will kick off her eighth Wimbledon — and her first wrapped in the green-and-gold — with what looks an eminently winnable opening-round tie on Tuesday against Colombian Emiliana Arango, the world No.76 who’s also on a four-match losing streak.

“Everything seems a bit different, I must say. It’s been a tough couple of years, especially the last couple of months, I had a lot of changes in my life and in my career,” said Kasatkina, who revealed that after Wimbledon she’d make her first visit to Australia since being granted permanent residency.

“It’s normal I need to be a little settled in my head. It takes time.

“In general, I am in the good place. And just as soon I get a little bit more stable, I’m sure things will go better, because I’m very happy with the decisions I made in my life.

“There have been small changes, which are huge changes, honestly, because I’m not used to this kind of treatment, feeling so much support. A little bit of pressure as well, because I want to show my best for the people who support me.

“I have to be fair here. You lose a few matches in a row, it’s not going to make you feel unbelievable — but at the same time, I feel good in my life. So this is kind of a balance which makes me alive. One tournament can change everything.”
