PARIS - World tennis No 1 Roger Federer has voiced his objection to the replay system that could be introduced at the US Open in August.
The United States Tennis Association (USTA) hopes to use the system, which will allow chair umpires to inspect disputed line calls instantly during thecourse of a match on a computer screen.
"I have a very strong opinion about it. I'm absolutely against it," the US Open men's champion said in Paris.
US Open tournament director Jim Curley has been attending the French Open to glean the opinion of the players after last year's quarterfinal match between Serena Williams and Jennifer Capriati was overshadowed by several officiating mistakes.
But Federer was adamant things should stay the way they are.
"I told him (Curley) about the difficulties, about how much money they will blow out by doing that because I think it's going to cost too much money," he said.
"We can use that for other reasons than (to settle) a couple of calls a match."
The USTA has held trials for the electronic line-calling aids and plan to run further tests in July after initial feedback did not prove too favourable.
