These are the best photos of players in shorts at the 2018 PGA Championship

The PGA Championship is the lone major that allows its players to practice in shorts.

With the August summer temperatures making for steamy practice rounds at Bellerive Country Club, it was a welcomed bonus.

Here's a look at some of the PGA's finest players who rocked the shorts best.

Rory McIlroy
