DARTMOUTH — Dennis Collins didn't waste any time pulling the trigger on a match-winning putt at the 18th hole in the semifinals of the 88th Annual CCNB Men's Fourball on Saturday.

With his team's match all even, Collins lagged a long putt to within nine feet. After watching the three other players in the foursome play out the hole, he stepped up quickly when it was his turn to putt and took care of business with a confident stroke right into the heart of the cup for a par four that closed out a 1-up win over the father-son team of Sean O'Connor (CCNB) and Brian O'Connor (Widows Walk Golf Course).

"I knew I had to make it and it was firm and in," said Collins, who joined CCNB this year from Reservation Golf Club in Mattapoisett. "I didn't really think a lot about it. I just took a deep breath and got it done."

The victory was set in motion at the par-4 16th hole, where Ben Vandal (Reservation) rolled in a clutch seven-footer for a birdie that evened the match. The teams then halved the par-3 17th to set the stage for Collins' heroics at the final hole.

Collins took advantage of a handicap stroke to make a 4-net-3 birdie at the fourth hole that gave the team a quick 2-up lead. The O'Connors then responded by winning the fifth, sixth and seventh holes to rally for a 1-up advantage.

Another 4-net-3 birdie by Collins, this one at the ninth hole, left the match even at the turn. Brian O'Connor made a 4-net-3 birdie at the 14th to push his team in front 2 up, but Collins and Vandal won the 15th with par threes to cut their deficit in half.

Vandal then stepped up at the 16th, where he let out a whoop after his putt dropped for a birdie three that left the match all square and proved to be a portend of good things to come.

"It was firm, left edge and uphill. I knew I had to get it there," Vandal said. "I hadn't been putting well all day, but uphill putts are good here. You can be aggressive with them."

By winning, Collins and Vandal put the kibosh on what probably would have been the first father-son versus father-son championship match in the history of the tournament.

Dr. Jeff Silva and Kevin Silva did their part for that scenario with a 2-up win over Tom Neves (CCNB) and Dan Scully (Reservation) that was also decided at the 18th.

The Silvas took a 1-up lead on a birdie by Kevin Silva at the uphill par-3 15th and the teams went on to halve the par-4 16th and the par-3 17th to set up a dramatic finish at the final hole.

That's where Jeff Silva came through with a 4-net-3 birdie that sent him into his third final at CCNB, an 11:45 a.m. matchup today against Collins and Vandal. Silva notched his first title in 2006 with his brother, Mike Silva, and he teamed with Steve Bastoni to win the 2015 championship.

"Kevin has been playing great all week," Jeff Silva said. "I've been helping out here and there and filling in where needed."

The Silvas are playing together for the second time as partners in the tournament and Kevin Silva said it's been a team effort.

"We've been playing well as a team and it's exciting to be in the final with my father," he said. "It's a blast playing in this tournament. I grew up playing this course and I've been around this tournament for a long time. Winning the championship would be a dream come true."
