birdie

A change of clothes leading to a change of fortune for the Californian who had four birdies in his final seven holes.

But Spaun birdied the 17th to move one clear and then produced his moment of magic on the final green to send the drenched masses surround the putting surface wild.

The 28-year-old world number 22 carded three birdies and two bogeys in his one-under 69 as he maintained his overnight lead and moved to four under par.

Another birdie from 20 feet at the 15th inched him to seven over par but frustration was never far away.

The American had four birdies in his opening eight holes and his is the only bogey-free round halfway through day one.
