Newton Square, Pennsylvania —

Somewhere around the 16th tee, just as Aldrich Potgieter was about to take a cut, a man in the gallery asked a pertinent question: “Is there anyone in this group worth watching?”

At the time, Potgieter, at 5-under, was atop the leaderboard at the PGA Championship. However, he now trails leaders Maverick McNealy and Alex Smalley by a stroke heading into the weekend at 3-under.

In defense of the curious gentleman, it was a fair question. While five-deep crowds chased the group of Rory McIlroy, Jon Rahm and Jordan Spieth around the course, only a few stragglers found their way to the ropes to watch Potgieter. He is more of a “who?”than a who’s who in golf.

As he continued to hold the lead during the second round, even those paid to know a thing or two about golf found themselves trying to figure just who he was on the fly. At one point, Sirius XM golf analysts debated on air how to pronounce the South African player’s first name.
