Mayfair in for Bubba at Torrey Pines
Masters champion Bubba Watson has withdrawn from the Farmers Insurance Open because of an illness.
Watson is a past champion at Torrey Pines, winning two years ago with a birdie putt on the final hole.
He tweeted Thursday: ''Pulling out of tourney this morning, don't have energy for golf. Feel the same as Maui.''
Watson had a stomach illness at Kapalua during the Tournament of Champions, where he tied for fourth.
Watson was to play with Phil Mickelson and defending champion Brandt Snedeker. He was replaced in the field by Billy Mayfair.
