It's challenging to reach the mountaintop once; it's practically impossible to remain there. Don't tell Brooks Koepka that it's practically unheard of to return to the summit.
One of the game's biggest stars, who had been dogged by knee ailments for the previous three years that made him doubt his ability to continue to rule the sport he once controlled, has now found his form.
Koepka shot back-to-back 4-under 66s to surge ahead of the illustrious field over the weekend.
He then added a 67 on Sunday to become the third golfer to win three or more PGA Championships during the era of stroke play, behind Tiger Woods and Jack Nicklaus.
While Koepka finished no better than 55th with two missed cuts in the four majors he competed in last season, he did have seven top-10 finishes over the 13 majors he played.
All of this supports the widespread belief that Koepka is among the greatest major championship competitors ever.
After raising the Wanamaker Trophy, Koepka stated, "I look back on where we were two years ago, everything that's gone on, and I'm just so happy right now that I'm kind of at a loss for words."
