Jack Draper made an incredible comeback to defeat Miomir Kecmanovic 5-7 7-6(9) 7-6(7) and reach the quarter-finals of the Adelaide International.
Draper saved two match points in the second set and was 4-1 down in the final set tie-break but came back to win in a match that lasted three hours and 39 minutes.
The result was a far cry from his blistering opening-round victory over Sebastian Baez, which he won in less than 90 minutes.
Draper will face top seed Tommy Paul after he beat Australian qualifier Jack Bolt 6-2 6-3 on Wednesday.
In an early contender for match of the year, Kecmanovic won a rollercoaster first set but squandered two match points in the second as Draper battled to force a decider.
There was controversy in that final set when the Serb refused to play for five minutes, seemingly due to his belief that a point Draper won in the tie-break saw the ball go under the net.
The umpire gave Draper the point which set up match point for the Brit, but he could not take it before finding a way over the line to reach the last eight.
