Sadly, this reminds me of their Wimbledon 2014 match.
It did me too.
Let us face it, Grigor was playing well again. In those last few games there were some wonderful returns. No shame to lose to a top twenty seed.
My immediate reaction was that Andy needed more power. Good build-ups but no unreturnable finishing shots. Grigor was retrieving like an Andy. It could have been partly due to reticence in his physical effort after the abdomen strain which must still be a worry.
