Speaking on Amazon Prime the pundit Barry Cowan commented on Alexander Zverev's tough season. The German player lost to Miomir Kecmanovic in Cincinnati on Wednesday. He hit 20 double faults in that match. "His form at the moment is worrying.

I’m actually really concerned about Zverev at the moment. His last four matches he’s played, he’s hit 36 double faults. He is actually missing 29 per cent of second serves he hits. So it doesn't matter how hard you fight and Zverev fights for every single point, eventually, that’s just going to get you down mentally.

And I think we saw that against [Karen] Khachanov on Friday when I couldn’t believe how poorly he started that match", said Cowan. Asked why Zverev is making those mistakes, Cowan replied: “I think it is technique.

I think he collapses on that second serve. A lot of the second serves end up going in the net. At six foot six, he needs to stay up on that serve. On the second serve, it is the same racket serve acceleration as your first serve.

The difference - a bit more spin. And at the moment we see a different second serves from Sascha. We see one at 125mph that is flat and he misses it long. And then we see the one that is 85mph that he decelerates and goes halfway up the net.

He needs to get that sorted first because otherwise, he’s just going to go match after match with that area of this game failing him."
