The two seniors, Chelmsford’s Joe Vecchione and Anders Klass of Braintree, were seemingly on a collision course in the 170-pound final at the Division 1 state wrestling championships for two days.

And in the end, it was Vecchione, the defending state champion, who prevailed, earning a back-and-forth 3-2 victory over Klass at Newton South on Saturday afternoon. And the two are likely headed for a rematch in the All-State finals next weekend at St. John’s Prep.

Vecchione’s victory also helped push Chelmsford, under the direction of coach Bruce Rich, to its second state championship in three seasons.The Lions (130) edged Springfield Central (111.5) for the title, with Putnam (93.5) placing third.

“For my finals’ matches, they’ve gotten harder every single year from my sophomore year to my senior year,’’ said Vecchione, the 160-pound Division 1 champion as a sophomore who is 45-1 this season.

“If I didn’t have the guys in the room pushing me, especially Evan Goodall [state champ at 145 pounds]. He helped me make this win possible.’’

Vecchione and Klass were favored, but as Vecchione noted, “Anybody could’ve made that final round.

“I obviously knew about [Klass]. He’s a good kid, really good wrestler, strong kid. Props to him, he did well, it was a great match and came down to the wire.’’

In the semifinals, Vecchione took out Springfield Central’s Dohnovin Harvey with a 2-0 win, helping Chelmsford gain ground in the team standings. The Lions also got valuable points from 106-pound champion Evan Kinney.

“We’re going to be state champions for the second time in my four years here and I couldn’t be more happy about that,’’ said Vecchione.

In the lower weights, Brockton senior Cole Wyman took his third D1 crown with an 8-0 win over West Springfield’s Calvin Curtis at 126 pounds.

St. John’s Prep 132-pound junior Ryan Garlitz was the tournament’s Outstanding Wrestler.

Division 2 — At Milton High, North Attleborough pinned down its third state title, accumulating 109 points to topple Central Catholic (105.5) and Nashoba Regional (105).

The Rocketeers sent six wrestlers to championships, with Mattuez Kudra earning the 220-pound crown to raise his season record to 38-4.

“There is no sport like our own,’’ said North Attleborough coach Wayne Griffin. “These kids work harder than anyone else and I’m proud that I get to be their coach.’’

Division 3 — One year after earning his first state championship, Melrose sophomore Hunter Adrian was on the cusp of a repeat at 106 pounds.

Standing in his way at Wakefield High was Pentucket Regional eighth-grader Tyler Knox, who had hopes of ending Adrian’s perfect 37-0 record.

Instead, Adrian defeated Knox via decision, 8-0, in a match that went all three rounds.

Adrian nearly pinned his way to the title through the tournament, having done so through the semifinals.

“It was great,’’ Adrian said. “Got the win, did what I had to do. Since first grade I’ve been working for it.’’

Melrose finished with 119.5 points, good for third place. Senior heavyweight Jonathan Cleveland carried Tri-Valley champion Dedham and first-year coach Wayne Sayers to the program’s first championship with 129 points, pinning Akhmet Azizov (Hampden Charter) at 5:20. Foxborough (127 points) was the runner-up.

Several accolades were presented, including coach of the year to Foxborough’s Bill Ivatts. Assistant coach of the year was awarded to Cohasset’s Mike Pimental.
