Defending champion Jordan Spieth clung to a one-stroke lead over Rory McIlroy after Friday's second round of the Masters, setting up a showcase third-round pairing of history-seeking golf superstars. Spieth, trying to become only the fourth back-to-back Masters winner, sank a 14-foot par putt at Augusta National's 18th hole to stay ahead of McIlroy, who would become only the sixth player to complete a career Grand Slam by capturing the green jacket. Ill winds gusted across Augusta National, the breezy conditions playing havoc with the world's most skilled shotmakers, who largely scrambled to contain the damage.
