Rain and wind delayed the 144th Open Championship at St. Andrews for over three hours on Friday morning.  And then darkness prevented 42 golfers from finishing Round 2 in the evening.

American Dustin Johnson (right) has the overnight lead at -10.  He leads England's Danny Willett by one shot, former Open champion Paul Lawrie and Jason Day are two shots back.

Masters and U.S. Open champion Jordan Spieth is at -5, tied for 15th.  Tiger Woods is at +5, he is likely to miss the 36 hole cut.
