Nate Lashley shared the lead with three holes to play at the AT&T Pebble Beach Pro-Am. After a fairway-splitting drive at the par-4 16th, Lashley's approach shot from 152 yards flew the green.
He pitched to 13 feet to give himself a solid chance to save par, but ran that effort 4 feet past the hole. He then lipped out his bogey putt and also missed a 3-footer for double bogey, ultimately making triple.
Lashley, who slammed his putter into the green on his way off, creating a gash in the putting surface, dropped from a share of the lead at 16 under to three back at 13 under.
