I guess it will be under 38.5 games in the final match between Novak Djokovic and Andy Murray. The Serb is extremely dynamic in all last games. He showed his paces against Roger Federer, especialy in first two sets. I don’t think that Andy Murray is able to force an action with his defensive play. It seems that he will play on the baseline mostly.
So Novak Djokovic will take his another title here.
