Former Gamecock tied for lead at PGA Professional National Championship

312 players are competing at the PGA Professional National Championship in Myrtle Beach.

Johan Kok shot an opening round 5-under par 67 to tie him for the lead at the PGA Professional National Championship in Myrtle Beach.

Kok, a former South Carolina Gamecocks golfer, shares the top spot with 48-year old Pennsylvania pro Dave McNabb, representing the Philadelphia PGA Section.

The first two rounds of the tournament are being played on both the Dunes Golf and Beach Club, and the Grande Dunes Golf Resort. The final two rounds will be played at the Dunes Club.

Kok, 34, carded his low score on the more difficult Dunes Club layout. He is playing out of the Tennessee PGA Section.

Former Coker College golfer Mark Sheftic stands at 1-under par after 18 holes. Sheftic, 39, is a PGA teaching professional at Merion Golf Club in Ardmore, Pennsylvania.

Defending champion Rod Perry shot even par 72. He is tied for 30th.

Only 29 players in the field of 312 broke par on day one. The top 20 finishers will earn a spot in the 2014 PGA Championship at Valhalla Golf Club in Louisville, Kentucky in August.
