There may have only been 75 overs possible on another weather affected day at Bready, but that was more than enough for Leinster Lightning to take control of their Championship clash against Leinster Lightning.
Play didn't get under way until 2pm, and Lightning had no hesitation in bowling first after George Dockrell won the toss.
Lightning handed a first-class debut to The Hills' Cormac MacLoughlin-Gavin after Barry McCarthy was ruled out with flu - Head Coach elect Nigel Jones assuming 12th man duties.
William Porterfield (25) added 35 for the opening wicket with Brendon Louw, but both were bowled by Peter Chase (2-24) in quick succession - the Irish skipper being the key wicket for the visitors.
Aaron Gillespie (22) and Stuart Thompson took the total to 70 for 2, before the wheels came off before and after tea,
Kevin O'Brien got one that nipped back to trap Thompson lbw, David Rankin edged Dockrell to slip, and Gillespie was bowled by Tyrone Kane just before tea, taken at 85 for 5.
The break didn't do the hosts any good, with wickets continuing to fall. Kane (2-25) trapped Warriors skipper McBrine, before Simi Singh claimed the first of his three wickets as he accounted for Graham Hume.
Craig Young and Boyd Rankin went quickly, before number 11 David Scanlon added some lusty blows in his 21 as Warriors finished 135 all out.
In 13 overs before the close, Lightning scored 49 for 1 - Jack Tector (15) the only casualty as he was bowled by Craig Young.
While a draw still seems the most likely result, there is sure to be a tricky period for the Warriors to negotiate in the final few hours.
They will need to bat better second time around or their Championship crown will suffer a major blow.
