Zverev M. vs Tomic B. prediction

Both Zverev and Tomic are great servers, and when they play on grass it is pretty hard to break them. Zverev played this season so far 7 matches on grass and only once the first set finished with less than 10 games. On the other side Tomic played 5 matches on grass and over/under 9,5 games score is 3-2. In the first round Zverev defeated Harrison after 6-4 in first set, while Tomic defeated Gombos after 7-6 in first set. These two players are very good on their serve and I expect at least 10 games in first set, but I would not be surprised to see here tie-break. Good luck
