Players feel the pressure of on-court mics - Andy Murray

Andy Murray has claimed that television's attempts to broadcast the words uttered on tennis courts put players under unique pressure.

The British No.1 is set to face the fiery Nick Kyrgios in the US Open first round on Tuesday, with the Australian at the centre of a sledging row after comments he made to world No.5 Stan Wawrinka.

While Murray indicated that he did not particularly want to be drawn into the debate over Kyrgios' behaviour, which Roger Federer said had "crossed the line" of acceptability, the Scot did question whether fans should have been able to hear the comments in the first place.

"For me it's like when I watch football on the TV, or basketball or team sports, they dumb the microphones down for the players, and when the fans are shouting stuff from the front rows of the crowd," Murray told British newspapers as he finalised his US Open preparations. "They don't want people that are listening back home to hear what the players are saying - or what the fans are saying - when they're on the court.

"And I feel that often in tennis [television is] desperate to hear what everyone's saying all of the time. The women have now got the coaching on the court and stuff ... I'm not against having the microphones on the court, I just think that it's quite different to other sports."

Murray faces a tricky first-round test in the form of Kyrgios, but after victory at the Rogers Cup in Toronto, the world No.3 should have more than enough to reach the second round of the year's final grand slam event.

The 2012 champion at Flushing Meadows will likely have to face Roger Federer in the semi-finals if he is to lift the US Open trophy once again, with the Swiss appearing to have Murray's number after winning their last five encounters.

Federer was unstoppable against Murray in their Wimbledon semi-final seven weeks ago, before coming unstuck against a dogged Novak Djokovic in the final. Ahead of his bid for a sixth U.S. Open title, he admitted the match against Murray took a lot out of him.

"Looking back at Wimbledon, maybe I peaked too much against Murray, then didn't quite play as well against Djokovic," Federer said. "Still, Novak causes different problems to Murray. Maybe it's also [about] match-ups and some days you just don't feel as good. Of course, I hope to save my best for last and usually you play better against the best players because you just have no choice."
