British No4 Kyle Edmund has scored the biggest payday of his tennis career to date with a shock fourth round victory over home favourite John Isner at the US Open.
Edmund will now face world No1 Novak Djokovic in a fourth round match which marks the furthest he has ever progressed at a Grand Slam tournament.
The 21-year-old beat big-serving Isner 6-4 3-6 6-2 7-6 across two hours and 43 minutes in Flushing Meadows, New York.
In doing so, he has guaranteed himself a career-high prize money paycheque of $235,000 (£176,765) from tennis' richest tournament.
Edmund, part of Great Britain's victorious Davis Cup winning team last year, caused the shock of the tournament so far by knocking out 2013 semi-finalist and world No14 Richard Gasquet in the first round.
But even if the British world No84 can't top that with a sensational triumph over reigning champion Djokovic when they meet on Sunday, he can take solace in a prize money reward that will increase his total career earnings by 31 per cent and put him on the cusp of the $1m mark.
The US Open is tennis' most generous tournament in terms of its pay outs to athletes, with this year's singles winners due to earn a record $3.5m.
Players who exit at the fourth round leave the competition with $235,000 in prize money - not too bad for less than a week's work.
That would take Edmund's career earnings from $758,328 to $993,328.
Prior to arriving at the US Open, the South African-born player's biggest payday came at Roland Garros in May where he took home €60,000 ($67,000/£50,400) for reaching the second round of the French Open.
Edmund and Djokovic have only met once before, at this year's hard court Miami Masters where the Serb cruised to a 6-3 6-3 victory.
