Mickelson -8
"Thanks for helping guys, I'll see you out there," says Phil Mickelson to marshalls who will follow his round.
He walks under the arch to tee one and gets some claps from the crowds at this course early today.
Phil's strength on day one was his work from the fairway, finding 89% of greens in regulation.
