Looks a very good bet. You might think Lopez would be the fav with his big serve, but Wawa is a great returner and like Murray,Joker can nullify a lot of opponents serves. Lopez also concedes a lot of aces and has done so in most of his matches here already. The stats look very good for Wawa here. He has comfortably out-aced Lopez in all but 1 of their meetings and I can see a repeat here. I managed to get 4/5 on Wawa but I think he's a strong fav here.
