St. Augustine Prep senior Jack Clark was impressive in defeating Clearview junior Ed Lenkowski in a battle of unbeatens at 152 pounds and was named the tournament's outstanding wrestler.
Clark, 21-0 in his first and only season as a South Jersey wrestler, was ahead by 17-6 when Lenkowski (30-1) injury-defaulted because of a shoulder ailment.
"I'm ready. I'm pumped," Clark said of chasing his first state title.
The top three finishers in each weight class will advance to the state championships, which will run March 7-9 at Boardwalk Hall in Atlantic City.
In a battle of unbeatens and longtime friends, Millville senior Ed Shockley defeated Lower Cape May senior Cory Damiana, 3-2, at 195 pounds.
Shockley (37-0), who has signed a football scholarship to Villanova, scored a first-period takedown and used that advantage to hold off Damiana (37-1) and capture his first region title.
"When you get that first takedown, it gives you a lot of confidence," Shockley said. "Against a great wrestler like Cory, when you get up, you can relax a little and just wrestle your match."
Like Dobzanski, who will pursue baseball, Shockley is in the final stages of his wrestling career.
"I want to go out with a bang," Shockley said.
In another battle of unbeatens, Hammonton senior Kellen Whitney (41-0) scored a takedown in overtime to defeat Clayton's Nick Rodriguez (34-1), 5-3, at 170 pounds.
Highland sophomore Lucas Siegfried won the 106 title with a 6-2 victory over Vineland junior Steve Bergamo.
"It's amazing," Siegfried said. "I was thinking, 'I'm the region champ.' "
Clearview senior John Van Brill improved to 36-0 by pinning St. Augustine's Jarred Hodges at 145.
Dobzanski's victory was his 86th in a row. He is 39-0 this season. He has allowed two points, both on escapes.
The defending champion at 220 with a career record of 151-8, Dobzanski will advance to his final state tournament next weekend with one goal: to finish one of the great careers in South Jersey history with a flourish.
Delsea coach Greg Sawyer, he said, "is working me harder than ever. I'm ready."
