ANN ARBOR, Mich. – Entering the day tied for 23rd, senior Peter Williamson (Hanover, N.H.) moved up nine spots into a tie for 12th at 2-under-par at the NCAA Central Regional in the 75-player field. He shot a 3-under 68 in the second round to shoot up the leaderboard. Julien Brun of TCU and Albin Choi of North Carolina State lead the tournament at 7-under. The event is being held at the par-71, 6,723-yard U-M Golf Course.

Williamson opened on the back nine on Friday with a bogey on his first hole, the par-4 10th. He bounced back with a birdie on the 532-yard par-5 11th. After a par on the 12th, he bogeyed the short par-4 13th. The senior carded an eagle on the 13th in the first round.

The Hanover native found his first string of success in the final five holes of the back nine. After posting a par on the 14th, he birdied the 15th and 16th. Williamson stumbled on the par-4 17th with a bogey, but closed out his opening nine with a birdie on the 455-yard par-4 18th. With four birdies, three bogeys and two pars through his first nine holes, Williamson shot a 1-under 34 to move to even-par for the tournament.

On the front nine, he pared his first two holes. Williamson moved to 2-under on the day and 1-under for the Regional with a birdie on the 554-yard par-5 third. After another par, he bogeyed the par-3 fifth, but responded with a birdie on the short 309-yard par-4 sixth. Williamson posted pars on the next two holes, but finished with his seventh birdie of the day on the 414-yard par-4 ninth to end his round. He finished the second day with a 3-under-par 68 to improve by four strokes from his first round 72.

The Ann Arbor Regional features 13 teams and 10 individuals playing 54-holes, Thursday through Saturday (May 17-19). The low five teams and the low individual not on an advancing team move on to the finals. TCU is currently in the top five teams, so Williamson probably doesn't need to overtake Brun. North Carolina State is four shots out of the top five teams, so Williamson will need to make up the five shots he is behind Choi.

In the team competition, USC leads at 7-under-par (561) and Oregon, Kent State and TCU are all tied for second at 6-under-par.

Williamson will start his final round on the 10th tee on Saturday at 9:50 a.m. He will be in the last group off the 10th tee.
