Dustin Johnson searches for 2nd major championship

Dustin Johnson is entering this weekend’s U.S. Open in Shinnecock Hills as the top ranked player in the world.     
He got over the hump at the U.S. Open two years ago, and hopes to be competing for his second major championship on the East End golf course.
Johnson won last week in Memphis. No golfer has won the week before the U.S. Open and gone on to win the following week.
