I missed the match.. got the wrong time, oh well.. Heard Milos didn't shake the umpire's hand after a bad call

And why don't they have hawk eye? stupid..
Still glad that Milos won the match though. But he looks exhausted. He's been playing tennis basically non stop for many weeks now. I understand if he loses the semifinal. It's totally understandable, and I won't blame him if he does.
