Caught a set of this as I got ready for work this morning. Andy looking pretty impressive off the forehand side. Keeping it powerful and he's flattened it out nicely. Worried about that 1st serve percentage though. That is totally not going to cut it against anyone else in his draw.
Hope he can sort that out by the end of the week.
I think he could serve the same percentage and still easily reach the quarters. Obviously that wouldn't be ideal, but I don't think his next 3 opponents will punish him.
