Even by tennis meltdown standards, Viktor Troicki's passionate rant at the Rome Open this week is among the best.

In the second set of a match against Ernests Gulbis, Troicki hit a backhand that appeared to hit the baseline. It was ruled "in" by the line judge, but that call was overturned by the chair umpire, Cedric Mourier. Troicki, who had lost the first set and was facing a break in the second, was livid. He yells at Mourier, saying "You know you're wrong!" and "You don't want to correct yourself." For several minutes during the changeover Troicki pleads his case, all to no avail.

Troicki even takes one of the cameras and leads it to the baseline, where he shows all the viewers at home why he is so adamant.

Amazingly, it appears Troicki is right. While the ruling might not have called for such a passionate argument, it does seem like Mourier overstepped his bounds in a) overturning the line judge's ruling and b) calling the ball out.
