Day ones in the books for the Tour Championship with Kevin Chappell, Dustin Johnson and Hideki Matsuyama sharing the lead at 4 under, and Phil Mickleson way back at 4 over.
But he'd have to claim shot of the day on the very first hole when he sank a monster 94 foot putt for birdie! His front nine form didn't stay at the level as he carded for 40, and 34 on the back nine.
Watch the putt here!
