Wilson leads after firing 62
The 47-year-old Wilson, from Fairfield, Calif., closed his round with a pair of eagles for a course-record 62 at the par-72, 7,420-yard Home Course – one of two courses used for the championship.
He had seven birdies, two eagles and one bogey, recording a 29 on the back nine.
The only lower 18-hole score was a 12-under 60 by Bill Horschel at the 2006 Amateur at Chaska Town, Minn.
The Amateur features 312 players from 15 countries. The first two days are stroke play at The Home Course and Chambers Bay. Five days of match play will follow at Chambers, with a 36-hole championship match Sunday.
