There's no way to sugarcoat it - he threw away a match against an inferior opponent. And one mentally who would have gone away in the 3rd set if Frank hadn't let him back in.
Frank better use this as an opportunity to qualify for San Jose cause this was just a disgrace.
I don't think I tried to sugarcoat it all. He played way too passive for most of the match. Of course it's not good enough to start hitting the ball again at that point. If I was trying to defend him here, I would say he got bullied by Williams. However if you allow yourself to get intimidated by a kid 7 years younger, it just underlines how mentally fragile he is.
I won't be surprised if he takes a break and waits for Memphis. He is probably both physically and mentally drained after both a long week, and a horrible loss.
