DUBLIN, Ohio - When he was asked about the latest version of the Big 3, Memorial Tournament host Jack Nicklaus was quick to point out there are plenty of talented players not far behind Jason Day, Jordan Spieth and Rory McIlroy.
Dustin Johnson reminded everyone Thursday at Muirfield Village that he is one of those players.
He made 10 birdies against two bogeys for an 8-under 64 and a one-stroke lead over Brendan Steele, who finished with a birdie on 17 and a hole-out eagle on 18 for a 65.
