Mickelson birdied his first two holes, went birdie-eagle on the short par-five fifth and sixth holes and closed with another birdie to shoot six-under 30 on the front nine. His fifth birdie of the back nine, on No. 16, meant that a birdie-birdie finish would leave him at 59, matching the tournament-record score set by David Duval and equaled by Adam Hadwin. His 18-foot birdie putt on 17 slid past the hole and effectively ended that possibility.
