Federer still mistrustful of Hawk-Eye
By Simon Cambers
MONTREAL, Aug 10 - World number one Roger Federer admitted he still does not trust the Hawk-Eye system that has been brought in to assist with disputed line-calls.
Hawk-Eye, which uses a number of cameras to determine where the ball has landed, has been met with a favourable response from most players, but the Wimbledon champion said he did not believe it was fully accurate.
"I still don't trust it 100 percent, I probably will never do," Federer said after beating Australia's Lleyton Hewitt 6-3 6-4 to reach the semi-finals of the Montreal Masters.
Under the rules, each player can make a maximum of two incorrect challenges per set.
"I had one in the first match against (Ivo) Karlovic. It was a serve, the mark's clearly out because you can see the marks here on this court.
"I couldn't believe it again when (Hawk-Eye said) it touched, it reminded me of the Wimbledon situation," the Swiss said referring to when Hawk-Eye ruled against Federer on an important call early in the fifth set of the final against Rafael Nadal.
"This is when it proves to me that the machine is not really working. That's also why you see many guys giving it a shot when they think it's an important point. You know it's out, but maybe it did clip the line, you know."
Against Hewitt on Friday, the Swiss was irked when what he thought was an ace on match point was called wide. He challenged the call and Hawk-Eye said the ball was out, by the smallest of margins.
"I felt it was kind of maybe more out than in, obviously," Federer said.
"But the tough part is to wait for it. Then you hit a second serve having basically 20 seconds in between. That is a tough part. Of course, it's my choice to challenge. But why not challenge? I would kill myself if it was in and I had not challenged."
Federer reiterated his feeling that tennis should allow line judges to call the lines, with only the umpire having the right to over-rule.
"I think they (the line judges) stare down that line and they know how the balls are coming," he said.
"They're used to it. They're professionals. I think they do an excellent job, because I wouldn't want to be sitting on that line. I just get disappointed when they miss shocking ones. But that can happen, too. I'm the guy who doesn't get too crazy about it. So it's okay."
