Even though Haase leads the head to head 2-0, I like Klizan to beat him today. I've made money picking certain spots on Klizan all last year and this is another good spot. The Slovak feels very comfortable on clay and that devastating forehand (one of the best on the tour) blends in nicely on this surface.
Klizan's game has matured very well on clay over the last 12 months and Haase is an opponent he can handle. Don't forget Haase has played 6 tiring sets of tennis the last 48 hours. Fitness and motivation level might be questionable for the Dutchman today.
Getting Klizan at only -160 is an excellent bargain in this spot.
Best of Luck
