The leaders are on the course

Dustin Johnson has been called the longest player in the tournament.  His tee shot on the first hole wasn't his best.  First tee jitters perhaps, understandable in the biggest round of his life.  It landed in the first cut of the rough with a decent lie.   He hit his approach shot right of the hole and sunk his par putt. 

Graeme McDowell hit the fairway, got to the green in two, but left his birdie putt far short and parred the hole.
