Gary Wilson's gamble failed as North West Warriors stunned the Northern Knights to win their first Interprovincial Cup game of the season in a thrilling finale at Stormont.

When the umpires brought the two captains together at 5.30pm, the consensus was that the game would be abandoned after almost 90 minutes of rain, but Knights skipper Wilson wanted the match to be played to a conclusion, with their new target another 85 runs in 11.3 overs with eight wickets standing.

With Wilson at the wicket, and the power-hitting of Shane Getkate, Mark Adair and Greg Thompson to come, it was unsurprising that the captain would back his team to finish the job against a young, inexperienced Warriors bowling line-up.

But it was Graham Kennedy, bowling four of the overs for just 17 runs, who put the Knights batsmen under pressure and as many of the attempts to clear the boundary fell into the hands of the Warriors fieldsmen, Knights still needed 15 off the last over, now with just three wickets left.

Gregory McFaul, on his Warriors debut, was entrusted with the final over, and with his fifth ball he had Graeme McCarter caught well inside the long-on boundary by Kennedy to confirm the shock.

Thompson hit the last ball for four but as they needed seven for the tie it was too late.

In the end, it was the loss of Marc Ellison and James McCollum in the eight completed overs before the rain arrived which upped the required run-rate for the Knights, and with Harry Tector scoring only seven from his first 13 balls on his return after the rain, the Warriors cashed in.

William Porterfield, captaining the team in place of Andy McBrine, who returns to lead the side in the three-day Championship game between the teams starting at Comber today, faced 95 balls for his 50 but was out immediately afterwards, skying a ball to the wicket-keeper.

His partnership with Aaron Gillespie, who reached his half-century seven balls quicker, was worth 100 runs but it never gained momentum and when Gillespie was out four overs later, Knights were in control.

With Getkate and Tector sharing seven wickets at less than four runs an over, there was no doubting the happier team at half time.
