Kamke is favorite at 1.80 and Zverev is at 1.90. Zverev is only 17 years old but he played vs kamke two weeks ago and beat him. That kid keeps establishing his name in the tennis world. I expect to hear more from him in the near future. His footwork has not been the best yet but his shots are.
I am going to back him today as the underdog in Hamburg prices at 1.90. Good Luck to all.
