>> A star is born at the US Open. I'm Reuters sports correspondent Steve Keating at Erin Hills, Wisconsin. The US Open is generally guarded as the toughest test in golf, testing a golfer both physically and mentally. And Erin Hills is expected to provide plenty of both this week.
At nearly 7,800 yards, this course is a monster, and it should suit golf's big hitters like Dustin Johnson, Rory McIlroy, and Jason Day, who just so happened to be the top three ranked players in the world. Problem is, all three come into this tournament with question marks hanging over their fitness and form.
Johnson missed the Masters because of a bad back, injured it in a trip at his home. And he was late arriving here, stayed at home for the birth of his second child. Roy McIlroy has been out of action for a month with rib and back injuries. And Jason Day is just now slowly starting to round into form.
Now if all these wasn't enough, there is the weather. Broiling hot one minute, rain the next, and you never know what to expect here. And with 156 golfers teeing it off, that could be the key word, unpredictability. Will the US open provide another surprise winner? We'll find out soon enough.
