"They were four for a few so we were pretty stoked to get a few cheap wickets," he said, before the coach-less Reds popped champagne in the dressing room to the team chorus of "We're the Texans".
Cornwall were 4-9 in 7.3 overs before wicketkeeper Seb Langridge and Jerome Groot stopped the rot as the visitors stuttered to 141 all out with nine balls remaining.
Freer said it was good to claim the scalps of the Smith brothers, captain Jacob and Jarrod, who had been in fine form this summer.
"Those guys got next to nothing but Seb did very well for them ... it was good to restrict them," he said, albeit fewer than 141 would have been better.
He singled out seamer Stevie Smidt for his five-wicket bag as well as a run out.
Fellow opener Liam Rukuwai was outstanding, stifling Cornwall with 1-10 from 10 overs, including four maidens.
Spinner Andy Thompson and Jayden Lennox were equally frugal.
The reply was an anti-climax as NTOB eclipsed the total in 28.5 overs.
Opening batsman Indika Senarathne scored a bolshie 61 from 46 balls, including 10 boundaries and two lusty sixes.
"We were going like 10 an over in the start," Freer said, admitting he had concerns because chasing wasn't easy.
"The boys get a bit more nervous," he revealed, adding NTOB traditionally often made hard work of it in one-dayers.
Their season-ending prize-giving ceremony shortly after the final was going to be a memorable one.
"The club puts up a few beers for us so we'll definitely enjoy it," he said as they claimed their 27th victory in about 100 years.
"We don't see one another much after that. You do a few times but you tend to hang out with different mates over winter."
Freer said they lost five games over summer, one in the one-dayers to Ruahine Motors Ford Central Hawke's Bay but gave his troops a pass mark.
"There are four trophies in a season and we got three so we're stoked," he said of the overall champions who lost the 55-over silverware to CHB.
It was a special day for veteran George Diack who played his 200th game after a late start to the season.
"There's not many guys who would hang around but he loves playing for Tech ... we need more [players like him]," he said, also thanking manager Dave Caldwell for performing a job that wasn't easy.
Aucklander Langridge, in his swansong for Cornwall, scored 68 runs from 35 balls, including seven boundaries, but it wasn't enough.
"We were staring down the barrel of one of those 40, 50 or 60 totals so to get to 140 - we were happy to get to that at one stage."
The wicketkeeper said consolidating became a key factor, regardless of the total they posted.
"We had to be there to give ourselves a chance.
"It's always sucks to lose. I always go out there trying to win," Langridge said, revealing they had a competitive score to defend and had succeeded in jangling NTOB's nerves at times.
"Indi [Senarathne] got away from us too much and we dropped him a couple of times so it didn't help our cause.
"At the end, we have only ourselves to blame," Langridge said, saluting Tech for setting the benchmark all summer while Cornwall did "what we can".
He was philosophical about not making the Central Districts Stags squad this summer with veteran Kruger van Wyk in "brilliant" form. "My job was to put pressure on him and I did that by putting on a couple of hundreds for Hawke's Bay.
"To be fair he [Van Wyk] was the CD player of the season and you can't take that away from him so I just enjoyed playing cricket for Hawke's Bay."
If the opportunity arose to play for CD A or the Stags he would grab it next summer.
Hopeful of landing a job in the marketing department of Air New Zealand in Auckland, the 23-year-old said he was waiting for a few interviews for a career in his hometown.
