Jim,
That's a great point, thanks for the reminder.
As it was Gary could have succumbed at any point over the weekend as several of the top 10 guys in the WGR we're lurking at one point or another... Brooks, Rose, Rory, DJ, Francesco, and Xander. Impressive stuff indeed!
P.S. I figure Phil has two good chances left to win the Career Slam (WF-2020, TPS-2021). Pinehurst is 2024, but by then I think it'll be too late.
