Quadrilateral: Mickelson Tries To Become Golf's Oldest Major Winner

Phil Mickelson Saturday at 16 (PGA Championship Instagram)

A stellar Saturday sets us up for a doozy Sunday at Kiawah.

Phil Mickelson leads by one over Brooks Koepka and looks to become the oldest male major champion.

Today’s Quadrilateral is only for the paying folks who will find some fun background on other geezers to contend or win, Saturday’s 13th hole situation, a possible lefty wind bias, the best Tweets, lots of TV notes and times, plus other stuff to get them ready for the final round.
