Luke Guthrie leads Honda Classic as McIlroy walks off, Woods struggles

Luke Guthrie had the best round of the tournament. He is in the lead going into the weekend at the Honda Classic.

And hardly anyone noticed.

Not on a day when defending champion Rory McIlroy walked off the course in the middle of his round. He told reporters he was "not in a good place mentally," and then released a statement saying his wisdom tooth was sore.

Tiger Woods was in danger of missing the cut, only to make a birdie and a tough par to barely make it.

And if that wasn't enough, Camilo Villegas went from first-to-worst. After opening with a 64, he was 13 shots worse Friday and became the first player in two years on the PGA Tour to go from leading to missing the cut.
