Not too hopeful but don't want to be too negative either. I do think it's strictly on Andy's hand to turn things around for himself and nothing else or nobody else can help him there.
Would like to see how the courts of Cincy and USO will play out this year. USO typically reflects Cincy so I guess we can go by that for now. Toronto courts were rather fast this year. Even Nole openly admitted it and said that it was more to Tsonga's advantage. Raonic, Lopez, Dimitrov, Tsonga not to mention Federer - they all did well on this surface. It would have benefited Andy too had he been a bit more careful. He too admitted that the courts were playing faster. We saw Nole, Wawrinka, Berdych all go out on the same day.
You can see and feel it when you watch the matches live in person. I was amazed at Andy's quickness at both matches vs Kyrgios and Tsonga. I really think Toronto delivered this time with most matches going to 3 sets and a few upsets early on.
