UL Eagles maintained their position at the top of the table despite a shock defeat at the hands of Killester on Saturday night.
Killester made home advantage count to take a deserved win, with coach Tom Doherty full of praise for his players afterwards.
"These guys give everything, they epitomise hard work and unselfishness. Limerick have beaten us a few times in succession so pride was at stake and I think we deserved the win," he said.
The Eagles saw their advantage at the summit cut to just one point as the UCC Demons emerged victorious from their scrap with Cork city rivals Bord Gais Neptune, while the university side also boast a game in hand.
Neptune rallied from a 17-point half-time deficit but couldn't quite reel in the Demons, with coach Paul Kelleher breathing a sigh of relief after his side held on.
"We need to start improving our second-half performances. That game should never have been that close at the end but we let them get out and start running in the second half, which they can do exceptionally well.
"We need to be more clinical, after a solid start by us they went on and buried us in the second half."
UCD Marian suffered from the absence of their American centre John Galvin as they fell to DCU Saints 81-65. The win moves Saints to fourth in the league after six wins and six losses this season.
Joseph Smith from Ballyhaise was best of a large entry in Co Cavan MC's Autocross at Latton, with his Escort almost two seconds ahead of the Civic of Darren O'Brien after three runs through the quarry.
Andrew McMahon took third place overall, with Billy Coleman Award winner Daniel McKenna taking a class win in his Escort.
Derek O'Connor has traditionally done very well at the Dromahane meeting, scoring a six-timer at the north Cork venue three years ago, but yesterday he had to settle for four winners.
Robert Tyner has been in top form with his horses and he provided three winners for the reigning champion. County Champions set the ball rolling in the opening mares' maiden. She had been third in a decent maiden last time behind Foxrock, with subsequent Limerick bumper winner Pumbaa behind her.
Bar Stool Bob and Sterling Stuff were O'Connor and Tyner's other winners in the four-year-old and five-year-old maidens, while O'Connor was at his absolute best aboard Suir View Girl for Sam Curling in the concluding mares' maiden.
Mikey O'Connor enjoyed a double on two very decent sorts. Michael Winters provided Allow Dallow, which was third on his last outing, to win impressively here.
O'Connor also scored with Cypian Prince when producing a classy display in the confined maiden for Louis Archdeacon.
