PINEHURST, N.C. - After taking the top spot during three rounds of stroke play at the 2012 North and South Amateur, former men's golf standout Peter Williamson has already earned his first two match play victories Friday.

Friday's match play is taking place on Pinehurst No. 2 after stroke play was held on Pinehurst No. 8.

Williamson, a 2012 Dartmouth graduate, finished two up on 16th-seeded Bryson DeChambeau in the day's first round of play thanks to two pars on the 17th and 18th to finish 2-over-par.

In his second round of the day, Williamson knocked off eighth-seeded Finley Ewing IV, 5 and 4. Three birdies through the first 12 holes gave the three-time Ivy League champion a comfortable lead that allowed him to move on to Saturday's semifinal round after just 14 holes of quarterfinal action.

Williamson will now square off against fourth-seeded Matt Ewald of Topeka, Ks., Saturday in the semis with an 8 a.m. scheduled tee time.

The North and South is the longest consecutive-running amateur golf championship in the United States today, now in its 112th year.
