Dustin Johnson took some attention away from the Big Three at the Memorial by opening with an 8-under 64.

Johnson is one of golf's biggest hitters. He began with three straight birdies and had two other bursts of birdies. He led by two shots over Hudson Swafford among the early starters Thursday. Johnson made 10 birdies at Muirfield Village and failed to birdie two of the par 5s.

As for the latest version of the Big Three?

Jordan Spieth saved his round with his putter, opening with seven one-putt greens. He finally started hitting fairways and greens and finished with a 70. Rory McIlroy, playing in Spieth's group, had too many mistakes in his round of 71.

Jason Day played in the afternoon and was 3 under through six holes.
