Challenge Rule Spurs an Angry Federer

After an extremely long challenge decision by Del Potro was granted by the umpire, Federer went off, which, if you’re talking about Federer, means the Swiss slightly raised his voice and threw a curse word or two in the mix for good measure.

It wasn’t exactly McEnroe-esque, but Federer told the ump “don’t tell me to be quiet,” and that “he didn’t give a s***” about Del Potro’s deliberation. That was when CBS cut away.

Very entertaining stuff. Federer is being tested here, and it’s getting to him. Plus, he really hates that stupid challege system. 2 + 2 = 4, etc.

For what it's worth, John McEnroe just said, in regards to the challenge system, that "everyone cheats" and the "system is a joke." Federer's frustration is not without merit.
