Havret found sand off his tee shot and was forced to lay up short of the green with his second shot, but McIlroy also ended in a greenside bunker with his approach.
While the hard ground - because of the underlying sand drying quickly - allows the ball to travel further from the tee, the ground off the fairway is far less forgiving.
But hopes of a straightforward victory for Els receded when his tee shot at the par-three 17th finished short and was plugged in an awful lie in the sand.
