The PGA Championship is serving up its version of the Big Three. Scottie Scheffler, Rory McIlroy and Xander Schauffele are Nos. 1, 2 and 3 in the world ranking.

The PGA Championship was first played in 1916 and was a match-play event for the first 42 years of its existence. It's been played every year except when it paused for 1917, 1918 and 1919 for World World I and 1943 due to World War II. In 1958 it changed to stroke play with Dow Finsterwald the first winner after the format changed.
