If Zverev is going to avoid facing constant pressure on his serve he must do two things: first, make a high percentage of first serves. He has done that effectively through five matches in Paris, hitting the mark on 68 per cent of his first deliveries.
Second, he must find a way to win at least half of his second-serve points. To do this he will have to keep his double-fault tally low.
This has been a thorn in the German's side for several seasons, and nothing has changed in Paris. Zverev leads all remaining men’s contenders with 27 double faults in five matches.
Longer rallies favour the Spaniard
Much of the talk coming into the tournament centred around Nadal’s fitness, due to left foot issues that surfaced during his round of 16 loss to Denis Shapovalov in Rome. But here in Paris, the Spaniard has proven that he is fit and able to grind out tough victories.
With his doctor by his side in Paris, Nadal is confident that he can keep pushing his body to the limit.
