When I checked the scores Andy was 2 sets down and 0-2 in the 3rd. Match over. Nearly fell off my chair when I heard he had won. Let's see how he pulls up. Even when Andy was at his peak a 5 setter in the 1st round of a Slam was not that unusual.
You just don't know what to expect from this tournament. Covid has to be a leveler because so many players will be relatively rusty. One match at a time for Andy but if he's still in the tournament next week then who knows.
