Phil Mickelson ‘embarrassed’ by moment of madness

The five-time major winner was four over par for the day on Saturday when he badly over-hit a putt on the 13th green and, seeing where it was headed, he ran around and struck it again, a breach of rule 14-5 which incurs a two-shot penalty.
A number of fellow professionals felt Mickelson should have been disqualified or withdrawn himself but he took his place in the field for the final round, eventually finishing joint 48th, 15 shots behind champion Brooks Koepka.
