Mikael Ymer beat Gael Monfils in four sets in the second round at the French Open on Thursday.
Ymer won the first set 6-0. His French opponent fought back to win the second 6-2 but during the third game of that set, the Swede showed some trademark fight and defence.
The 22-year-old - who is ranked 105 in the world - withstood a barrage from Monfils in an incredible 33-shot rally, on several occasions making unlikely returns.
It was Ymer who served. Though Monfils, ranked 15th in the world, almost immediately took the upper hand as he stretched his opponent across the court.

"Absolutely incredible, a couple of gets there from Ymer were simply world-class," former British pro Arvind Parmar said on Eurosport.
"Yet [against] so many other players they would have been winners and Monfils was just running out of idea in the end. There was just no way through.
"His father was a professional marathon runner so it’s in his blood, doing laps there."
Ymer went on to win the third set 6-4 and the third 6-3. He will face the Italian, Jannik Sinner, in the third round.
