Emma Raducanu, Jack Draper and Sonay Kartal – why are so many British tennis players injured?

Of the six British singles players who began the year in the top 100, Cameron Norrie is the only one to have avoided injury or illness, and he has returned impressively to the world’s top 20 in recent weeks.

Raducanu, 23, had been due to return at the Italian Open in Rome this week but withdrew after her media commitments on Tuesday with post-viral symptoms. Kartal is currently on track to reappear during the grass-court season, but the back injury the 24-year-old suffered during her run to the Indian Wells fourth round in March has cost her the entire clay swing.

Francesca Jones had a month out after a glute injury at the Australian Open and Draper’s comeback from his serious arm injury has been checked by a knee problem, while Fearnley came through qualifying in Rome after a seven-week absence.

British number three Katie Boulter, who tumbled out of the top 100 last year as she battled foot and hip injuries, says it can be hard to step away even if players have information to suggest their bodies are at breaking point.

Fitness trackers, which offer performance analysts a wealth of data, will be allowed on a trial basis at this year’s remaining three Grand Slams, as they have been for a while now on the men’s and women’s tours.

But Boulter, who has climbed back into the top 60, told BBC Sport: “I think it’s impossible as a tennis player to be like, ‘I’m going to take the week off because my wearable [device] says that I’m in red’.

“Financially, there might be people that don’t have that luxury to stop a week out of their schedule and not play – the majority of us are still trying to make a living.

“I’ve played through many injuries, I’ve also stopped through many injuries. Ultimately you have to make the best judgement call you can.

“It’s good to have that information, but it doesn’t necessarily marry up sometimes.”

The LTA has refreshed its entire physiotherapy staff over the past 18 months and believes it now has the right expertise to support the modern player. The next task is to consider how best to upgrade its recovery facilities.

British players have a lot more resources at their disposal than many other nationalities. An LTA physio was sent to Miami in March as Kartal started to realise the extent of her back problem, but the emphasis is also on players building their own support network.
