One might think ATP tennis players are rarely mistaken for one another, because of their unique character, mannerisms, distinct facial features and playing style. However, itt turns out many tour players are misidentified all the time, and how they handle it varies.

Good friends John Isner and Sam Querrey are often mixed up: Isner doesn't bother to correct fans, gladly posing for pictures and even signing his compatriot's autograph. When Querrey is mistaken for Isner, he's a bit mischievous. Querrey simply ignores fans, which in his mind, creates disdain for Isner and leads to gaining more support for himself down the road.

While training last summer, a fan approached Felix Auger-Aliassime's hitting partner thinking he was the teenage Canadian. The mistaken identity trend doesn't appear to be fading away any time soon, and if Querrey has it his way, the fans will all be flocking to his corner.
