On Friday morning, by the time he reached the ninth hole of his second round, Rory McIlroy was, he said, "seeing red." His bottom right impacted wisdom tooth, which is being treated by his childhood dentist in Belfast, was causing him pain. His "out of sorts" swing was causing him more pain. His scorecard through eight holes -- par, double bogey, par, bogey, par, par, triple bogey, bogey -- was causing him the most pain. When his second shot on the 18th hole at PGA National, home course for the Honda Classic, settled in a pond, McIlroy's mind was overwhelmed with a single thought: "I don't want to be here."
