McDowell establishing lead, Els hits tough stretch

Graeme McDowell is beginning to seperate himself from the pack.

While everyone else makes unforced errors, McDowell is playing bogey-free golf.  He is one-under on the day, with a birdie on the par-3 5th, and at four-under for the tournament. 

Ernie Els looked like McDowell's biggest threat until he reached No. 9.  He bogeyed the hole then shot a double bogey on No. 10 and a bogey on No. 11 to fall to one-over on the day and the tournament, five strokes behind the leader.
