TRUCKEE, Calif. — England's Sam Horsfield routed two more opponents Thursday at Martis Camp Club to advance to the quarterfinals in the rain-delayed U.S. Junior Amateur.
The 16-year-old Horsfield beat Nick Hardy of Northbrook, Ill., 8 and 7 in the second round, and topped Mexico's Aaron Terrazas 6 and 5 to beat darkness in the third round. On Wednesday in the first round, Horsfield pounded Dean Sakata of Diamond Bar, Calif., 7 and 6.
"I am hitting it a lot farther," Horsfield said. "I probably gained 30 yards and have been going to the gym two or three times a week, which has helped my fitness. It helps with courses like this."
Horsfield will face 15-year-old John Augenstein of Owensboro, Ky., on Friday morning.
Augenstein outlasted stroke-play medalist Jim Liu, the 2010 winner from Smithtown, N.Y., in 20 holes in the second round, and edged Brian Carlson of Madison, Conn., 1 up with a 5-foot birdie putt in the third round.
"I am exhausted," Augenstein said. "This is only the second tournament I have played 36 holes in one day — the qualifier and today. My first goal was to make it to match play and give myself a chance to move on and after that it was to win."
In the other upper-bracket quarterfinal, China's Dou Zecheng will face Davis Riley of Hattiesburg, Miss. Dou beat Zachary Bauchou of Forest, Va., 2 and 1, and Riley topped Trevor Phillips of Inman, S.C., also 2 and 1.
In the lower bracket, Doug Ghim of Arlington Heights, Ill., beat Corey Eddings of Roseville, Calif., 4 and 3, and the other three matches were all square when they were suspended because of darkness.
Ghim will face the winner of the match between Cameron Young of Scarborough, N.Y., and George Cunningham of Tucson, Ariz. They played 18 before play was called for the night.
In the other matches, Scottie Scheffler of Dallas and Justin Suh of San Jose, Calif., completed 15 holes, and Nick Heinen of Edmond, Okla., and P.J. Samiere of Kailua, Hawaii, finished 14 holes.
The 36-hole final is Saturday.
