What happened in the TB? Not watching but was following on live score.
He's already lost a couple of set points, and then there was some kind of distraction going on - maybe the umpire and a ball boy- but the camera didn't show. Anyway, after that he lost a few more and the set, his errors mostly.
Saved a couple (at least) MPs at *4-5 15-40, turned it back on and that Lahoyne umpire was checking something and called it out (I assume Munar would have won), Cam won the next 3 points to hold. 5-5*, no breaks this set.
And just like that he's taken it into a decider. Obviously mindset wouldn't be the same so not quite as black and white, but if only he'd taken one of those many chances in the first set.
