Phil Mickelson stunned the sports world last May by winning the PGA Championship at age 50, becoming the oldest player to win a major championship.
Since then, he has been steeped in controversy because of derisive comments he made to Golf Digest and the Fire Pit Collective about the PGA Tour and the Saudi Arabian regime bankrolling a rival golf league.
Mickelson skipped the Masters in April, and, although he's officially registered to play in the PGA Championship on May 19-22 at Southern Hills in Tulsa, Okla., there's no guarantee he'll be there.
