Daniil Medvedev defeated tournament debutant Diego Schwartzman 6-3, 6-3 to set up a mouth-watering semi-final clash with Rafael Nadal in the ATP Finals at the O2 Arena here.

The win over Schwartzmann enabled him to complete 3-0 run in Group Tokyo 1970. It is a massive improvement from last year when he went winless. The Russian's match against Nadal will take place in the early hours of Sunday (India time)
"I was playing great in the two previous matches. I think it is always good to stay undefeated for the confidence. I wanted to win the match, so I am really happy that I have done it," said Medvedev after the match. "I was serving really well today, so that helped me a lot throughout all the match."

Nadal leads their career head-to-head series 3-0, including a stunning comeback from 5-1 down in the third set of their clash at last year's Nitto ATP Finals.
