Zverev vs Sock prediction

Winners goes though in this ATP finals contest between two rookies in this event : Zverev and Sock. My pick here goes with the american Sock. Nice odds at 2.50 on bet365. Jack just fresh off his masters win in Paris , on the same surface , looks really confident out there. I see more confidence in him then in Zverev who came into this tournament after 2 losses in a row. He's not playing the best tennis of his season, and maybe he's starting to pay off this really long season. Sock played 20 less matches then Zverev, this is an important factor late in the season. Sock's confidence is back and he's now in the top 10 and can make a statement by beating Zverev. He won their last meeting on this surface and he's been playing really really well this year under the radar. Jack for the win good luck!!
