Alexei Popyrin and John Millman will take on each other on Tuesday July 26 in the first round of the 2022 Atlanta open.
In 2011, Popyrin won the Australian u12s Grasscourt Championships and, with Chase Ferguson, won the u12s National Claycourt Doubles.
Popyrin did hold the advantage in the third set, as he led 5-2, but Nadal pulled it back to 5-5 before ending the match in a tie-breaker.
Alexei Popyrin, who will face defending French Open champion Rafael Nadal in the first round, believes he has a chance of winning his match.
The Spaniard eases past the Aussie in straight sets to enter the last-8 in Madrid Open for the 15th time.
