Wimbledon final
Perhaps the worst call of the year was actually a decision. The powers that be at Wimbledon decided they had seen enough fifth sets go on and on and on… So, they decided to install a tiebreak when the score reached 12–12 in the final set of any match. Of course, it played little role in the tournament until the men’s final when, instead of playing on, Novak Djokovic won the crown over Roger Federer in a tiebreak.
