Bryson DeChambeau has charged home to slow Rory McIlroy's tear towards a 25-year golfing first and set up a thrilling final-day Masters duel.
McIlroy (12 under), targeting golf's first career grand slam since Tiger Woods completed his at the 2000 British Open, lit up Augusta National early on Saturday with a historic birdie-eagle-birdie start.
His nemesis DeChambeau answered in the shadows, nailing a 50-foot birdie putt on the 18th to sit just two shots back.
