You should modify it to accept last names only. Sometimes, I can't be bothered to recall players' first names. Like if I just input Federer, it doesn't accept it, it has to be Roger Federer. Who other Federer could it be anyway?
At the end of Federer's first round match at the Australian Open a fawning interviewer asked about his kids and if he had bought coach Stefan Edberg a birthday present - no, by the way, the privilege of knocking up with 'King Roger' was enough of a present apparently.
