British number two Dan Evans upset 25th seed Lucas Pouille to set up a US Open third round clash with Roger Federer.
The 29-year-old from Birmingham produced one of his finest displays since returning to the sport 18 months ago to beat Pouille.
Evans took the first two sets and survived a fightback from the 25-year-old to seal an impressive 6-4, 6-3, 6-7, 6-4 victory on Court 12.
Evans took advantage of a lacklustre display from Pouille, racing into a two-set lead and a break up in the third.
Frenchman Pouille belatedly found his range and broke Evans twice with the finish line in sight.

Evans hit back to level the set but then blew a 3-0 lead in the tie-break.
However, Evans finished the job in the fourth set to set up a third career clash with 20-time grand slam winner Federer.
The world number 58 has yet to take a set off the Swiss star, but he pushed him close in Australia earlier this year.
Federer's slow starts at Flushing Meadows - conceding the first in each of his two matches so far - will give Evans some hope of causing an upset.
