Defending champion Stefanos Tsitsipas recovered from 0-4 down in the final set to defeat Diego Schwartzman on Friday to reach the Monte Carlo Masters semi-finals where he will face Olympic champion Alexander Zverev.

Greek third seed Tsitsipas had been a set and 5-2 ahead at one stage and seemingly cruising to the last four. However, his Argentine opponent hit back only to be thwarted in a quarter-final which wrapped up at 11:00pm local time.
