Paul Stirling's debut for Northern Knights proved to be a winning one, with a brilliant unbeaten 41 which ensured a 2-run win (DLS) at Bready.
Stirling's 41 came from just 24 balls, with his two sixes hit into a gale force wind that had made conditions incredibly difficult all day.
In gusts of up to 60mph Stirling unveiled his full repertoire of sweeps - reverse and conventional, powerful pulls and perhaps the shot of the day, an outrageous dilscoop off Graham Hume.
He had lost opening partner James McCollum (1) early, as the Waringstown man picked out Nathan McGuire at deep square, and a leading edge by Harry Tector gave Hume (2-15) his second wicket.
Stirling continued to thrill, and with Gary Wilson had Knights 10 ahead as the rain clouds gathered over the hills.
Wilson attempted to hit rival skipper Andy McBrine over the clubhouse but Stuart Thompson took a well judged running catch just inside the ropes as the first drops of rain fell.
Stirling then took no chances in the next four balls as the rain got heavier, and the players were forced from the field, never to return - Knights two runs winners on DLS.
Earlier, play was delayed by 15 minutes and Knights had no hesitation in inserting the Warriors.
The home side gave a debut to Nathan McGuire, while the Knights gave three new caps to Stirling, CJ van der Walt and Ross Adair.
McGuire fell early, bowled top of off stump as he charged Graeme McCarter.
Wickets continued to fall as David Rankin was trapped lbw by Mulder, Stuart Thompson caught at long on off Pretorius and McBrine caught by McCollum to give McCarter (2-17) his second wicket.
William Porterfield played well for his 42, showing his experience by targeting the short boundary, made even shorter by the tail winds.
Will Smale was well caught behind by Wilson, and when Harry Tector - who bowled excellently - deceived Porterfield, Warriors were in deep trouble at 80 for 6.
Graham Hume (47*) in conjunction with Ross Allen rallied the hosts with an unbroken stand of 52 in six overs to get them up to 132 for 6.
Hume struck two massive sixes one over long-on and the other over extra cover in a fine knock, showcasing his all-round talent.
Both sides are in action next week with the Knights hosting Leinster on Tuesday at Comber, while the Warriors travel to Dublin to play them at Pembroke on Thursday.
