Ian Siebers, 16, of Bellevue, Wash., shot an impressive 4-under par 68 to catapult into the clubhouse lead. Siebers turned in a clean card with four birdies versus no bogeys.
William Moll, 17, of Houston, currently stands second in the clubhouse at 5 under for the championship, following a 1-under 71. Starting on the back nine, Moll overcame four bogeys overall, with five birdies respectively on Nos. 17, 18, 2, 4 and 7.
Among those who finished their round, four players are in a tie for third at 4 under. This includes Travis Vick, 18, also of Houston, who matched Moll with a 71 for the day. His scorecard also reflected a five birdie, four bogey round.
Also in the group is first-round co-leader Campbell Kremer, who cooled off with a 2-over 74, following a personal best 6-under 66 on Tuesday. Kremer is the great-grandson of Valhalla founder Dwight Gahm.
“I still have a lot of confidence in the course, and I think I should play well the next two days,” said Kremer.
BYU commit Cole Ponich, 18, of Farmington, Utah, shot an even par-72 to also have a share of third—among finishers on the day—while University of Georgia commit Nicolas Cassidy, 17, of Johns Creek, Ga., carded a 1-under 71 (69-71 140).
Still on the course are two players tied at 6 under for the overall lead. First round co-leader Ryan Grauman, of Alamo, Calif., is even-par through nine holes carded. Luke Kluver, of Norfolk, Neb., is 1 under for his round through 11 holes played. Also on the course is defending champion Akshay Bhatia who is 3 over through eight holes and is currently T-18 overall.
