Geesaman went to his trademark cradle to build an 11-0 lead before pinning Herzog early in the second period for a 38-31 Waynesboro win, the Indians' first of the season.
"Nathan went out and took it to him," said Indians coach Aaron Taylor. "It was a big win for us at home, especially against a rival like Chambersburg."
However, Taylor said he knew his team had the victory locked up after the evening's fifth bout at 171. That's where Waynesboro sophomore Bobby Hall picked up his first career win in dramatic fashion, pinning Jeff Dehart for a 20-9 Tribe lead.
"The big clincher was at 171," said Taylor. "I wasn't expecting to win that match, especially by pin."
Waynesboro's Chad Lasley then pinned Colin Campbell at 189, giving the hosts their biggest lead of the night at 26-9.
But the Trojans (0-3, 0-3 Colonial) quickly answered with three straight wins, getting a 15-6 major from Bryan Crist at 215, a 3-2 decision from Justin Gipe at 275 and a win by forfeit at 103 to cut their deficit to 26-22.
With Waynesboro (1-1, 1-1 Colonial) staring at another forfeit at 119, Indian Chip Stover's third-period pin at 112 proved huge.
"I just figured I had to go out there and do it for my team," said Stover, who gave his team a 10-point cushion. "I just rolled a half-nelson, put him on his back and stuck it."
Following the forfeit, the Trojans made it a one-point match on Bryan Rowland's 5-1 decision over Ryan Hight at 125. But that's as close as it got.
"We got the matchups we wanted," said Chambersburg coach Doug Rine. "But we got pinned in a couple of swing matches that I thought looked even."
Chambersburg went up 6-0 on Caleb Davis' win by fall at 135. Waynesboro responded with a tech fall from Brian Lisko at 140, a decision by Eric Kelley at 145 and a pin by Derek Hook at 152 to take the lead for good at 14-6.
