Power to the Player: Tennis Players Who Challenged Calls More



Challenging a call is often a tough path to tackle. Good thing, there’s Hawk-Eye, the on-court computer replay system, to guide the umpire and linespeople to revert the call in their favour.

In an article published in the New York Times, a study suggests that tennis players should challenge “out” calls more than “in” calls because the probability of the officials erring an out than an in is high. 

Nonetheless, this should not count as bad refereeing. Instead, it has to do with the inherent bias of human perception of moving objects like the tennis balls.

Power to the tennis players

Based on statistics also, the lower-ranked tennis players who challenged a call are more often right compared with top players. 

This is empowering in the sense that the challenge rule gives the tennis players a voice and a chance to overturn the rule without resorting to violent reactions.

Before we proceed with the names of tennis players who challenged calls more, these are the things you need to know about challenging calls in tennis.
