McIlroy sets another US Open mark for 8-shot lead.

With each remarkable round, with each record-setting performance, Rory McIlroy is making that Masters debacle seem like a distant memory.A U.S. Open title could erase it altogether.McIlroy moved closer to his first major Saturday at Congressional by stretching his lead for the third straight day with a 3-under 68 to set the 54-hole record at the U.S. Open — a mind-boggling 14-under 199 — and build an eight-shot lead going into the final round.That's twice the size of his lead going into the last day at Augusta National.And this time, the 22-year-old Northern Irishman says he has learned from his mistakes.
