Rory McIlroy is challenging for his first major championship in record-breaking style.  McIlroy has set a 54-hole record at the U.S. Open.

The 22-year-old from Northern Ireland stands alone on top the leaderboard at the U.S. Open.  Rory McIlroy shot 3-under-par on Saturday to finish at 14-under through three rounds.  His 14-under 199 breaks Jim Furyk's record for the best 54-hole score by one stroke.

McIlroy has an eight-stroke lead on Y.E. Yang who finds himself at 6-under through three rounds.  Although McIlroy melted down at The Masters, he is not showing any signs of surrendering his lead tomorrow.

History is also on McIlroy's side.  The largest 54-hole lead ever surrendered in a major was a 6-shot lead at the 1996 Masters by Greg Norman.  Norman shot a 78 in the final round while Nick Faldo shot a 67 to win by five strokes.  McIlroy's eight-stroke lead seems to be insurmountable.
