The Munster Reds made their debut in the Hanley Energy T20 compeition which ended in narrow 9-run loss (DLS) against the Northern Knights in a rain-affected contest.
Adam Dennison (33) and Graeme McCarter (25) led the Knights out of the traps as they raced to 82 for 2 in just 8 overs.
However, they were pegged back by a superb spell from Stephan Grobler (3-12) which saw them faltering at 123 for 8 after 15 overs when the rain interrupted their innings.
On the resumption, Munster needed a DLS adjusted 121 to win, but despite a quite brilliant 59 from 40 balls by Jack Tector (7 fours, 1 six), he received little in the way of meaningful support when play was halted by bad light with Munster 92 for 5 after 13 overs.
That meant the Knights were declared 9-run winners on a day when the elements intervened to ruin what should have been an historic occasion.
Irish international Jacob Mulder enjoyed a successful return to action after his back injury to claim 2 for 13, while former international Gary Kidd also picked up a brace.
The next action in the competition is on Monday, when the Warriors host Knights in a 50-over game at Strabane, followed by the maiden first-class match between the same opponents at Eglinton on Tuesday.
