North Hagerstown's David Broadwater (119) and Williamsport's Ryan Bowers - the county's only other finalists - both finished second. Broadwater fell 16-5 to Northwest's Danny Hansen and Bowers lost 12-0 to Frederick's Mark Tsikerdanos, who was voted the tournament's Outstanding Wrestler.
"It was disappointing. I thought we'd have a lot more kids from Washington County in the finals," Broadwater said. "But it's a tough tournament. A lot of tough teams come through here."
Walt Whitman beat them all, topping the 18-team field with 187 points, 9.5 points ahead of Walkersville, which finished second for the second straight year. Paint Branch was third with 160.
The Herald-Mail top-ranked Lions sent five wrestlers to the finals, but only received title points from Gleason Sweeney, who topped Damascus' Ricky Flynn 5-3 in overtime in the 103 final.
"It was tough," Walkersville coach Scott McIntosh said. "But I'm thrilled. It was a very competitive tournament. It's just nice to get our guys banging heads with other top guys."
The area's only other champion was Thomas Johnson's Mark Esmont, who pinned his way through the bracket at 189. Esmont pinned Rockville's Patrick Haddon in 3:01 in the final, overcoming a 5-0 deficit early in the first period.
Short and Cotterman both overcame deficits against each other on their way to a 4-4 tie after two periods at 135.
After being called for stalling with 45 seconds left, Cotterman, seemingly trying to avoid giving up a penalty point from the top position, allowed Short to escape, giving the Wildcat a 5-4 lead.
"Thank God for the stalling call. He was controlling me on top," Short said. "He let me up and that was a relief because I knew I could take him down."
Short rounded out the scoring with a takedown in the closing moments.
"I knew it was going to be a battle out there," he said.

The third-place finishers included: North Hagerstown's Dean Staley (171), Williamsport's Spencer Peyton (119) and Adam Bridendolph (140), Walkersville's Danny Neel (160) and Billy Burke (215) and Middletown's Ryan Tice (112), Matt Maddox (130) and Mike Schlepp (135).
