I watched from 3-3 in the second set, although it was good to see Andy win and he seemed fitter and sharper towards the end. However he only won in my opinion due to Haase running out of steam and was clearly injured from the start of the third set. Even when he broke and held for 3-0 it was clear that Andy if he kept the momentum up and played the right shots he would come through.
A win is a win though, delighted to see it. Rublev should beat him but Andy will try and frustrate him and he has a chance depending on what Rublev turns up.
