Zverev 6-4 3-6 Nadal
A grunt from Nadal as he serves and he secures the point with a forehand winner down the line.
Big hitting from both players now, Zverev lobbing high and Nadal responds with an equally strong smash. The ball is in the air for an age but it's Nadal who gets the final touch to get the point.
Set point - and Nadal is the one with the fist pump as Zverev hits his forehand into the net.
