I think anyone watching today’s men’s semi-finals matches at Wimbledon would agree that the high-tech line calling machine was out of whack. Twice Roger Federer suggested the machine was wrong, and Andy Roddick did so several times, even though the result of the challenge went in his favor. John McEnroe agreed that the machine was providing inaccurate video images, and we all know that he knows a thing or two about line calls. Mac was matter of fact when he said “Generally when you see chalk fly the ball was in.” But the replay were so so far off you have to wonder. Federer even went as as to suggest it was the wrong point being displayed. I like the whole challenge rule, but when the machine isn’t working correctly, the umpire need to step-up and take charge with overrules. Otherwise it looks as though the linesman and players are the ones that are wrong.
