Can we see this as some sort of a redemption match for all his numerous chokes in the past? The latest disaster was at RG, where he himself led 2-0 and held match points against Diego Schwartzman. Other close matches that didn't go his way: vs Dimitrov Toronto 2014, vs Nadal Paris 2015. And of course he led Novak Djokovic by 2 sets in 2015 at Wimbledon, and even had some BPs in the fifth set. For once he actually didn't lose courage - he kept serving huge, held his nerve on the big points and took advantage when his opponent faltered on MP. As disappointing as the Fed loss was, I have to give credit to Anderson - by far his biggest scalp to date. I don't know if he'll be able to beat Isner, but in his mind he must feel relieved to have partially made up for all the missed opportunities in the past.
