Jack Draper has already produced the standout run of his career to reach the US Open semi-finals.
Now, to become only the fourth Briton to reach the men’s singles final, 22-year-old Draper faces the task of beating the leading player in the men’s game.
Italian world number one Jannik Sinner, who seems to have put the controversy of testing positive for a banned substance behind him, stands in 25th seed Draper’s way when the pair meet in New York on Friday.
Awaiting in the final will be an American man, with Taylor Fritz facing Frances Tiafoe in the match afterwards.
Former US Open finalist Greg Rusedski says his fellow Briton has got “a real shot” at causing a shock.
“There is not much expectation on him because he is not the favourite,” Rusedski, a big-serving leftie like Draper who was the 1997 runner-up, told BBC Sport.
“If Jack can play with freedom he definitely has a chance.”
There will be BBC 5 Live coverage from 19:00 BST as well as live text commentary on the BBC Sport website and app.
