Not worrying about his body breaking down means Draper can have more trust in executing his key weapons, which are well-suited to the grass.
Coach James Trotman, a fellow Briton who has come through the LTA’s coaching pathway, is helping Draper learn how to play aggressively in the right moments.
That means being willing to play higher-risk drop-shots and spring forwards to the net, as well as unleashing his groundstrokes from the baseline.
“He’s much more aware what his strengths are – that is the biggest change this year,” said Leon Smith, Britain’s Davis Cup captain.
“You don’t want to be extending points if you have the chance to get the first strike in.
“He’s not afraid to step in and be brave, including in the big moments.”
Being willing to take risks under pressure has been where Draper has excelled this season, according to the ATP statistics.
Draper is second behind world number one Sinner in the Tour’s ‘under pressure rating’ – which combines the percentage of break points converted, break points saved, tie-breaks won and deciding sets won.
