AUGUSTA — Well that escalated quickly.
Rory McIlroy opened his Masters title defense with a 5-under 67 where he didn't have his best stuff yet still scored, but then Friday exploded late with six birdies in his last seven holes including the last four to shoot 65 and post 12-under 132 through 36 holes. He leads by six shots over Sam Burns and Patrick Reed, a record margin for the halfway point at the Masters.
