This will be their first meeting.
It was an excellent season in 2016 for Zverev. He has continued his strong form in 2017. He reached the quarter finals in Melbourne and beat world number 1 Murray in 4 sets.
De Schepper is also in decent form and has reached 2 Challenger quarter finals this year. He has come through the qualifying rounds this week with identical scores in each match ( 7-6, 6-2).
I think the sets will be tight and De Schepper could take a tie break but I favour Zverev to win.
Back Zverev if he is broken first or loses set 1. He starts around 1.45.
