Alexei Popyrin has braved the hottest conditions he's ever played in to beat Swiss veteran Stan Wawrinka and set up a third-round meeting with defending Olympic tennis champion Alexander Zverev.
Popyrin, the only Australian left in the singles draw, triumphed 6-4 7-5 on Tuesday in temperatures hitting the high thirties at Roland Garros.
"I think it's probably one of the hottest conditions I've ever played in - and I'm from Australia, so that's saying something," smiled the Sydneysider.
