An inspired spell of fast bowling by North Tamworth captain Adam Greentree has left the grand final against Old Boys evenly poised after wickets tumbled on day one at No 1 Oval on Saturday.
The 36-year-old finished with his best figures of the season - 7-30 off 15 overs - as the reigning two-time premiers were dismissed for 70 in 31 overs.
Earlier, Norths - who are attempting to win their first premiership since 2012-13 - were removed for 74 after being sent in by Old Boys, who are gunning for their seventh title in eight seasons.
Old Boys' veteran quick, Troy Sands, took 4-23 off 19 overs to continue his excellent form this season.
Only five batsmen reached double figures, with Norths No 5 Brendan Rixon the top-scorer after compiling a 106-ball 32.
In their second innings, Norths finished the day on 3-46. Peters made a 48-ball 37, with Michael Rixon not out six and Dobson yet to score.
Play resumes on Sunday - the final day.
North Tamworth got off to a dreadful start when Old Boys paceman Aaron Hazlewood removed Redbacks opener Lincoln Peters for two and No 3 Chris Dobson for six.
Sands chimed in by dismissing opener Toby Smith for one, leaving Norths at 3-19 - soon to be 4-21 when the competition's leading run-scorer, Michael Rixon, fell to Dylan Smith for 13.
Hazlewood finished with 2-20 off 24 overs, while Smith took 2-22 off 11.3 overs.
Norths only used two bowlers, with Cameron Reeves proving a good foil for Greentree after taking 3-34 off 16 overs.
Veteran opener Simon Norvill top-scored for Old Boys with 13.
Greentree, who debuted in first grade at Norths at age 17, told the Leader in 2017 that he would keep playing until the side won another premiership.
On the eve of the grand final, he said: "I'm still happy with the way I'm performing. I'm on the decline, obviously, because age gets the better of ya. But I'm still happy with how I'm releasing the ball."
