The U.S. Open at Merion Golf Club begins Thursday morning, and when it does begin it'll probably be with some falling rain. 

Not ideal, especially after some rain on Monday.

But if they do play, fans will be treated to a couple of marquee groups, including one with massive star power: Tiger Woods, Adam Scott and Rory McIlroy.

Dan Moscaritolo has more from the U.S. Open.
