Miami Open: Daniil Medvedev beats Pedro Martinez to reach last 16

After reaching the Miami Open last 16 he is two wins away from regaining the men's world number one spot.

After a long time at the top of the rankings, Novak Djokovic was overtaken by Medvedev last month.

If he reaches the semi-finals, the Russian will take over again.

The US Open champion advanced to the fourth round with a 6-3 6-4 win.

The courts here are slow, so playing against a Spaniard is not easy, but I played well.

I felt like we had a lot of rallies where he was bringing the pace down and I couldn't do much.

I tried to serve well, keep consistent and make less errors.
