Wilson played his final six holes in 3 over for a 75, which would have left him tied for 16th at 6-under 138.
But he left the scoring trailer without signing his card.
'First time as a pro,' Wilson said as he cleaned out his locker.
It already has been a busy two weeks for Wilson. He was not given a sponsor's exemption at the Sony Open ' despite being the only PGA Tour player from Hawaii ' getting in as the fourth alternate. He finished 76th.
He got off to a good start at the Buick Invitational until his oversight Saturday morning. It was a costly mistake considering Wilson likely will get into only two more tournaments during the West Coast swing because of his low-ranking status coming out of Q-school.
Wilson, who won two majors on the Japanese tour, is best known for playing with Annika Sorenstam the first two rounds at the 2003 Colonial.
