WEST CALDWELL, N.J.—Paul Simson and Curtis Skinner won quarterfinal and semifinal matches Wednesday to advance to the USGA Senior Amateur final at wet and foggy Mountain Ridge Country Club.

The 61-year-old Simson, the 2010 winner from Raleigh, N.C., beat Jim Knoll of Sunnyvale, Calif., 3 and 2 in the semifinals.

"I have about another 15 minutes to celebrate and then I have to get ready for tomorrow," said Simson, who grew up in nearby Chatham. "I had it going today. I knew I was going to have a tough match with Jim and I just can't get over some of the things I did out there. I think I hit every fairway and every green."

The 55-year-old Skinner, from Lake Bluff, Ill., edged Douglas Hanzel, of Savannah, Ga., 2 and 1.

"My intent was to make the cut and win one match," said Skinner, making his first appearance in the event for players 55 and older. "I've been in a couple of absolute dogfights and I am happy to come out ahead."

In the morning quarterfinals, Simson led Stephen Sharpe of Greensboro, N.C., 5 up after 10 holes when Sharpe conceded the match following a rain delay. Skinner beat Steve Golliher of Knoxville, Tenn., 2 and 1. Skinner also finished off his suspended third-round match, beating Canada's Graham Cooke in 19 holes.
