I hope Andy can play as well as possible tomorrow, and doesn't have lapses if he's in a winning position. It's so dangerous to do that against a great server like Tsonga.
But he was very close to winning in Toronto, and you'd think the five set format would give him more of an advantage. Hopefully that and his great head-to-head record against Tsonga will give him confidence tomorrow.
Unfortunately I can see this match being subject to rain delays because I've looked at three different forecasts, all of which predict thunderstorms for the late afternoon and evening, and tonight's matches have been subject to rain delays. A roof is being put on AA but that isn't likely to happen until 2017.
One factor in this match could be the heat and humidity, both of which will be high enough to make conditions pretty uncomfortable, so hopefully Andy's Miami training will kick in.
