At the 2018 WGC-Mexico Championship, Phil Mickelson won his 44th (and most recent) PGA Tour event. At age 49, it is very reasonable to wonder whether this will end up being Mickelson's final PGA Tour victory. This is a custom embroidered 17th hole flag likely produced by someone affiliated with Phil Mickelson. Mickelson won the event in a 1 hole playoff against Justin Thomas on the Par 3 17th hole. This rare flag contains a large Phil Mickelson autograph.
