DUBLIN, Ohio – Jon Rahm showed Saturday why he's such an explosive player, with his clubs.It just might be what takes him to No.
1 in the world.Rahm was four shots behind as he played the 12th hole at Muirfield Village. Then, he ran off four straight birdies in firm, fast and scary conditions for a 4-under 68 that gave him a four-shot lead over Tony Finau and Ryan Palmer.Rahm can go to No.
1 in the world for the first time with a victory Sunday, provided Rory McIlroy is not a runner-up. McIlroy was 10 shots back after a 72, not a bad effort on this day where the course average was 73.07.Finau provided plenty of help.
