Columbia Regional

COLUMBIA, Mo. -- The Columbia Regional is one of the most competitive regional sites in this year's NCAA tournament. To advance to the NCAA finals in Prairie Dunes, Kansas, May 23-28, teams must finish within the top 5 at the Columbia Regional.

Oklahoma State (-16), ranked No. 2 nationally, is leading the 14-team field heading into the second round. No. 11 Virginia (-3) played a great back nine after an hour rain delay to finish the day in third. The Tigers finished the first day of competition in front of several highly ranked programs including No. 24 Arkansas (E), No. 14 LSU (+1) and No. 26 Arizona State (+3).

Sophomore Jordan Niebrugge blistered the par-72, 7,141-yard layout with a bogey-free 65 to lead senior teammate Talor Gooch by two strokes. Niebrugge birdied three of his first five holes before adding his fourth birdie of the day at the par-5 ninth to turn at 4-under 32. After opening his back nine with three pars, he reeled off birdies at the 13th, 15th and 17th to move to 7-under par for his round and match his low score of the year.

Round 2 of the 2014 NCAA Columbia Regional begins at 9 a.m. ET Friday.

The Blazers were in a close battle at the top of the leaderboard, but back-to-back birdies on the 17th hole (No. 8) helped pushed them in front of No. 9 Illinois.

Several players got off to great starts despite the tough weather conditions. Senior Wilson McDonald, who is tied for fourth with an even 72 on the day, birdied two of his first three holes.

Raleigh Regional

Raleigh, N.C. -- Following a two-plus-hour weather delay, play was called for the day with Georgia Tech four shots ahead of Washington during the opening round of the NCAA Raleigh Regional at the Lonnie Poole Golf Course.

Tech senior Richard Werenski, working on a 5-under-par round, was preparing to hit a 15-foot birdie putt on the 18th hole when the horn sounded, halting play at 12:40 p.m. Fellow senior Bo Andrews, playing in his hometown, was on the 18th tee having played the first 17 holes in 4-under-par. Ollie Schniederjans (-3 through 14) and Seth Reeves (-2 through 15) also were playing well for the Yellow Jackets.

Play was called for the day at 2:45 p.m. with heavy downpours having soaked the 7,213-yard, par-72 course for more than two hours and no break expected. Due the amount of rain the course has absorbed, play will not resume Friday morning until 11:30 a.m. NCAA officials still hope to complete round two Friday as well.
