With all of the cameras and spectators, it's extremely rare to lose a ball in a professional tournament, let alone a major.
But earlier today on the 6th hole at Birkdale, a wayward second shot from Phil Mickelson ended up in the fescue. After the designated five minutes to look for the ball was up, no one could find it, resulting in a triple bogey for Mickelson.
During TGC's post game show, Brandel Chamblee went out to number six after the first round was completed, and threw three balls into the same rough where Phil's second shot seemed to have landed. The balls were no where in sight when Chamblee walked over to the general location.
What else can tournament officials do to address this? Increase the already large amount of marshalls?
