Yeah, I am not confused at all, the sponsor's exemption referenced is for next week's Charles Schwab Challenge. The PGA Championship does not have a sponsor exemption.
The PGA Professional Championship is always a great watch, as they are super talented guys who still want to grind but need that weekly check. This year's tourney had quite the drama at the top 20 mark, which is the automatic entry for the PGA Championship. J.J. Killeen, who is a fairly popular social media PGA Professional needed a 5 footer for par to make the PGA Championship, which he did.
