A delighted but weary Edmondson said the loss of two early wickets had put the Dave Castle-coached side under the pump a little but it required "anyone" to get himself in.
However, it wasn't anyone that did it but the Crowe and Horwath accountant from Hastings who wouldn't mind a stint with the Stags, for the record, after his maiden double century (229) against Wairarapa in 2017.
Schmulian 56 runs and No 6 Christian Leopard's 59 also will plot the turning points of the game for the bragging rights to the symbol of minor cricket association supremacy when the dust settles tomorrow.
Nerves overnight, Edmondson?
"Oh I'll sleep pretty well although I'm sure I'll have a little bit [of nerves] but at the moment I'm not too bothered because I'll keep batting," he said with a laugh, grateful to his teammates for their input.
"It was good fun. I kept grinding and I had all these guys who worked real hard with me as well and they just kept talking about getting through."
Edmondson said the wicket was slow and flat, taking a while for batsmen to get themselves in if they had wanted to cash in.
Nelson new-ball seamer Jarrod McKay made the initial inroad with the scalps of Wiggins and Smith to finish with the figures of 2-68 from 13 overs, including a maiden.
Fellow opener Josh Newport (1-41), first-change bowler Thomas Zohrab (1-70) and second-change spin merchant Felix Murray (1-121) claimed a scalp each.
Captain Willem Ludick, who won some respect with fellow CD tweaker Murray, rolled out seven bowlers to try to contain the Bay.
"The spinners bowled pretty tight so I didn't give them anything," Edmondson said.
However, how much toll the whole day and good part of tomorrow will have on their fitness, never mind the mental fatigue, remains to be seen when their turn comes to ask for middle and leg.
He anticipated occupying the crease for another session, at least, tomorrow before the potent bowling line up will embark on their campaign to skittle the hosts twice over on the promise of a follow-on.
Edmondson has now made four centuries for the Bay side and five, mostly white-ball ones, for his national champion NTOB team bound for Auckland to defend their crown next month.
However, the opener said he had fancied his chances perhaps more as a white-ball player than a red-ball one.
Ruahine Motors Central Hawke's Bay CC premier men's skipper, Dominic Thompson, was named 12th man.
