Just before lunch, I saw Andy was two sets down, assumed he was finished and forgot about it. Just before I left work, I clocked that he was serving for set 4. I got home just in time to see him make the decisive break and then serve it out. I can't tell you how full of admiration I am for this guy and his refusal to lose.
As you say, he's probably going to go down with a bit of a whimper against Bautista Agut, but that he's made it this far at all is incredible. Hopefully, he can drag himself up the rankings a bit and avoid players like Berretini in the first round, would obviously make his life a lot easier.
Stupid time for a tennis match to finish though, the organisers need to look at that.
