The Northern Irishman also ran into traffic along the way to the course, but made it just in time, eating a breakfast bar and giving a "relieved-looking" Jose Maria Olazabal a hug.

"Finally we got hold of him and he came in with a police escort with 10 or 11 minutes to go."
He teed off on time in the day's third match.
