The format features each player joined by an amateur partner or a celebrity, like the AT&T Pebble Beach National Pro-Am on the PGA Tour. The 14 lowest-scoring teams (seven pro-celeb and seven pro-am) advance to play in Sunday's final round. The cut in this event does not occur until after 54 holes.
For the first time in Nationwide Tour history, play is spread throughout three courses over the first three rounds - The Cliffs Valley Course at the Cliffs Golf & Country Club, The Cliffs at Keowee Vineyards and The Cliffs at Walnut Cove. The Cliffs Valley Course is a par-72 layout, while the other two are par 71s. The Cliffs Valley Course will host Sunday's final round.
Goggin's 65 came at the Cliffs Valley Course. Watson shot a 7-under 64 at the Keowee Vineyards Course and is 10 under par at the midway point.
Goggin opened on the back nine Friday and birdied his first hole, No. 10. He added birdies at 13, 17 and 18 to make the turn at 4-under-par 32.
On the second nine, Goggin parred his first five holes before a birdie at the par-5 sixth. At the par-5 ninth, Goggin chipped in for an eagle from 30 yards to grab his two-shot lead.
'I made the most of my opportunities today,' said Goggin, who is 52nd on the Nationwide Tour money list. 'Putting has been the key for me the first two days. Chipping it well is a bit of a bonus.'
This marked the third time Goggin held a second-round lead on the Nationwide Tour. He held the lead at the 1999 Lehigh Valley Open, an event he went on to win, and at the 1999 Upstate Classic, which was the previous name for the BMW Charity Pro-Am at The Cliffs.
'I'm leading my part of the rotation after two days which is what you have to do,' said Goggin, who also won the 1999 Omaha Classic. 'It is tough to keep your focus during a five-and-a-half-hour round, but I managed to do that most of the day. It was sort of a patience day for me.'
Jon Mills, one of three first-round co-leaders, shot a 2-under 70 at Cliffs Valley and is alone in third place at 9-under-par 134.
Charley Hoffman, Joseph Alfieri, Kyle Thompson, Scott Weatherly, Andrew Johnson and Robert Garrigus, who fired a 10-under-par 62 on Friday at Cliffs Valley, are tied for fourth place at minus-8.
