STILLWATER, Okla. — Oregon's Norman Xiong is one shot off the lead during the opening round of the NCAA Men's Golf Championships on Friday at Karsten Creek.

Xiong shot a 4-under 68 on the 7,460-yard course during an incomplete first round that was suspended at 8:38 p.m. CDT time because of darkness.

UNLV's Shintaro Ban and Northwestern's Ryan Lumsden each shot 5-under 67s. Texas Tech's Ivan Ramirez was at 5 under through 12 holes and Clemson's Bryson Nimmer was at 5 under through 10 holes.

Xiong, the top-ranked individual player in the NCAA, was tied with three others at 4 under, including Oklahoma's Quade Cummins, Kent State's Chase Johnson and Texas' Scottie Scheffler. Scheffler was through 10 holes in his opening round, and the others all completed their rounds.

Four other golfers are at 3 under.

While Xiong had a strong start, the rest of the Ducks struggled as Oregon ended the day tied for 26th out of 30 teams at 8-over 296 with Arkansas and Arizona State, and one shot behind 25th-place UCLA. Northwestern leads the team race at 8-under 280, three shots ahead of Oklahoma, which didn't finish its round, and four shots ahead of Texas Tech, which also didn't finish its round.

Oregon put only three golfers in the top 100 as Donald Kay shot a 74 and was tied for 80th and Edwin Yi shot a 75 and was tied for 99th.

Stanford is the top Pac-12 team, tied for 14th place at 4-over 292.

The top 15 teams and top nine individuals after Sunday's third round advance to match-play competition Monday with the individual title to be decided in Monday's fourth round.
