Getting your player ready...
Two tennis players are locked in a furious baseline exchange. Eventually, a line judge calls the ball “out.” Should the player who lost the point protest the ruling? Yes, a new study suggests. Researchers say professional tennis players could increase their chances of having a ruling reversed in their favor by an instant replay review if they challenge “out” calls more than “in” calls. A study of 57 randomly selected matches during the 2007 Wimbledon tournament found officials were more likely to err by calling a shot “out” than “in.” Scientists say it has to do with a bias in the way humans perceive moving objects.
