"It's just a dream come true for her," said Laurel golf coach Sue Matson. "She's been working on this for a very long time and I couldn't be more proud of her."
It was the 10th consecutive tournament victory for Webinger, who finished as runner-up to Clancy at last year's state meet.
"She's an incredible player," Webinger said of Clancy. "We've always been battling against each other, so it feels good to be able to finally come out on top."
Matson, who left the team Saturday morning to catch a flight to Savannah, Ga., where she will play in the USAGA National Team event beginning on Sunday, added that Webinger's focus played a key role in the victory.
"She's been extremely focused all year and that carried over to this weekend," Matson said. "She had a great practice round on Wednesday and carried it into the tournament."
It didn't come easy for Webinger, who held a five-shot advantage over Whitefish's Erin Tabish entering Saturday's final round in which she shot an 82. Tabish tallied an 84 while Clancy finished strong, carding a 78 on Saturday.
"I think I put a little bit too much pressure on myself this morning," Webinger admitted. "But I guess it worked out for the best. I was glad to have it over with, but at the same time it was just an incredible moment."
In the team race, Polson overcame a seven-stroke deficit following Friday's round to cruise to its first team title since 2005, shooting 784, 20 shots better than Livingston. Laurel, which was leading after the opening round, rounded out the top three with a team score of 806.
Billings Central finished eighth in the girls race.
On the boys side, Eli Rogers and the Hamilton Broncs took advantage of playing on their home course as Rogers shot a 66 in the final round to earn a four-stroke victory over Livingston's Willson Decker. Hamilton ran away with its second consecutive team title.
Livingston, Whitefish and Sidney finished second through fourth, respectively, with just two strokes separating the schools.
Dylan Meccage finished fourth in the individual race for Laurel with a two-day total of 149.
"Overall, I couldn't be happier with the way we competed this weekend," Matson added. "On the girls side we didn't even have enough to field a team score a few weeks ago, so to place third is really a Cinderella story.
"And on the boys side they kept improving throughout the entire season. We didn't take home any hardware but they didn't quit and I'm just extremely proud of them -- on and off the golf course."
