HONOLULU -- Mark Wilson won't be around this weekend to defend his Sony Open in Hawaii championship.

"Short game kind of let me down yesterday," said Wilson, who bogeyed five of the seven greens that he missed in regulation in the first round.

Wilson made five bogeys on Thursday, the same amount he made during all 72 holes in last year's win at Waialae.

Although he played better on Friday -- he was a bogey-free 3 under in his first eight holes before losing momentum -- he felt like he didn't get enough out of his round.

"I don't know how I only shot 2 under to be honest with you," he said.

He added: "It just was one of those weeks where is it didn't seem like things were going in my favor. I felt like I hit a lot of good shots that ended up poorly and didn't make as many long putts as I normally do, and there was the difference."
