Stan Wawrinka vs. Alexander Zverev
Zverev is a young player with a lot of power and snap in his lanky frame. Stan Wawrinka is coming off of his 3rd major title and seeks his 5th tournament win of 2016. If Stan takes care of his service games, my guess is the pressure will shift to the younger player who is seeking his first title. Stan can have uneven results, but my guess is in a tournament final he will bring his better self. Stan likely wins a close match given how much power Zverev can produce.
My Prediction: Stan Wawrinka d. Alexander Zverev 7-6, 6-4
