Murray, with the momentum behind him, was outraged and loudly complained to the officials -- "That's not fair," he said.
He later revealed that Janowicz, who has soared up the rankings since reaching last year's Paris Masters final, had spent the delay making a mobile phone call.
"He seemed very relaxed. That's the sort of player he is, that's why he is very loose on the court," was Murray's verdict.
When they emerged for the second time, Murray almost immediately broke Janowicz's service and saw it through to the finish, winning with a whipped forehand to reach his second straight Wimbledon final.
