Instonians blew their chance to win the NCU Premier League outright after losing by four wickets to Civil Service North today at Stormont.
The defeat allowed Waringstown, whose victory over Lurgan relegated the Pollock Park side, to share the title with a fifth successive league win.
And North Down, winners over a hugely disappointing Lisburn side at Wallace Park, can make it a three-way tie by beating Civil Service North at Stormont tomorrow.
Inst will be left to rue a spectacular late-season collapse, with three defeats in their last four matches costing them a first outright title since 1962.
The writing was on the wall from an early stage as the superb Allen Coulter took the big wickets of Neil Russell, John Stevenson and Carleon Brome.
Andrew White and James Shannon threatened to turn the innings around but the dismissal of Shannon, was arguably the game’s defining moment.
White went on to top score with 42 but he was one of four victims as Inst were dismissed for just 111.
The game was back in the balance as CSNI slumped to 43 for five.
Nigel Jones struck three fours and five sixes in an unbeaten 55 from just 48 balls as Inst lost by four wickets.
Waringstown meanwhile cruised to a nine-wicket win as Lurgan were dismissed for just 161.
Neil Anderson made a fine half-century but that total was at least 100 short on a brilliant batting wicket.
James Hall and Kyle McCallan both struck unbeaten half centuries as they romped home.
Lurgan were relegated on net run rate despite finishing level on points with CIYMS, who will consider themselves lucky to escape the drop.
