When the last three wicks fell for the addition of just 22 runs, MAGS had slumped to their first loss of the season which had already produced wins in the one-day championship and Knockout Cup.
As soon as that game ended, with Brett Bakkerus claiming 5-42 as the visitors fell 26 runs short of their target, the MAGS players headed to Auckland Grammar to watch that drama unfold.
After dismissing St Kentigern for a much-improved 229 in their second innings, the Auckland Grammar openers strode to the crease with their team needing to score 132 from 18 overs to claim not only outright points but the championship as well.
On paper the target did not appear too onerous but the loss of wickets and a steady flow of runs had the match in the balance.
At the start of the last over AGS needed seven runs and the visitors two wickets for outright points.
It got down to the last ball with one run and one wicket required. A run out ended both team's hopes and the match was tied - much to the delight of the band of MAGS' players and supporters.
For long-time MAGS coach Tony Sail it was just reward for the hard work put in at the school.
At Rosmini, Sacred Heart resumed their first innings at 116/4, still shy of Rosmini's first innings 167. Led by the prolific Glen Phillips (59) and support from Tom Ritchie (46 not out), the visitors reached 218 for the loss of only one further wicket.
Batting a second time, Rosmini, with runs from Kieran Seedall (74), Simon Rajwer (40) and Alex Durand (30), posted 216 to leave Sacred Heart needing 167 to win from 23 overs.
They lost seven wickets along the way as Connor Ridge capped a good match in claiming 5-39 but that was not enough as the visitors reached 166/7 with one over to spare.
King's can now contemplate a return to the champion grade next year after their 42-run win over St Peter's.
Chasing the 254 scored by King's on the first day and resuming at 110/7, St Peter's batted to within 41 runs of their target in scoring 214.
King's batted for a second time and, led by 138 from Tristan Payle, posted 216/4 declared leaving the home team 256 for outright victory. They reached 204 but that was not enough and King's claimed the points and the championship plate.
Rangitoto had a chance to claim the honours but things came unstuck after they had played themselves into a strong position by claiming first innings points from Macleans.
After dismissing Macleans for 125 the home team struggled to reach 149 despite a Ullrich Boshoff half-century and a useful 31 from Isaac Snell in the face of some steady leg-spin bowling from Kanav Dogra who bagged 5-35 from 6.1 overs and good wicketkeeping by Adam Baard.
Needing 178 from 40 overs, Macleans lost two quick wickets but an unbeaten 60 from Liam Winn eventually got his team home.
