With Ballynahinch and Dungannon drawing on Friday night, Belfast Harlequins’ home victory over Galwegians has put them top of the pile in Division 1B.
Today's 19-13 triumph over the westerners represents a fourth successive win for ‘Quins who are motoring along nicely with scrum half Ian Porter taking the plaudits again.
Porter converted a 35th minute penalty try and kicked four penalties in all for a 19-point personal haul.
‘Wegians hit back in the second half with a late try from flanker David O’Hara to earn a losing bonus point, but a 60th minute kick from Porter effectively put the hosts out of sight.
At Eaton Park, home advantage helped Ballymena see off Bruff on a 17-8 scoreline and move up to third in the table.
Luke Marshall and Brian Cahill traded penalties in the opening half, before tries from Ulster-capped centre Marshall and lock Andrew Kerr saw the Braidmen make it two wins on the bounce.
Centre David Lynch had UCD on course for full points against Buccaneers, with his first half brace moving them into a 12-0 interval lead at Belfield.
However, Buccs came good in the second period to take a 16-15 verdict, aided by an Alex Hayman try and 11 points from the boot of talented young out-half Jack Carty.
Neither UL Bohemians or UCC could manage a first half score in this afternoon's mudfest at Annacotty, but the dominant UL pack got on top in the second half to carve out a 8-3 victory.
Following a series of close-in scrums, Bohs number 8 Sean Rennisson got in for a try after 48 minutes and Ben Martin kicked a penalty seven minutes later.
UCC fluffed a penalty chance before full-back Luke Duffy was on target after 68 minutes.
UL had suffered an early setback when they lost their highly rated Munster-contracted prop Dave Kilcoyne with an eye injury after only two minutes, and Garry Walsh took his place.
