Milos Raonic vs Alex Zverev prediction

In my first opinion, Zverev deserve being favourite on this meeting. Zverev had beaten Raonic 2-0 on their first meeting just months ago in Rome where conditions are quite slow. Both players hold their serve more than 90 percent. But Raonic breaks at around 10 percent while Zverev breaks more than 20 percent. Both players have big serve. Considering they will play on slow conditions, Zverev has slightly advantage. Raonic needs to hold his serve at best if he wants to win. In this circumstances, I see several tie breaks are likely and I like the odds for 1st set will see more than 10 games.
