Ronan eases Shannon drop fears
Shannon maintained their recent improvement with a 45-26 home victory over Cork Constitution.
The comprehensive win, which moves Shannon from bottom to third last in Division 1A, suggests that they are well capable of moving further away from relegation trouble.
Once again, Munster flanker Niall Ronan was among their try scorers. They got six in total, with the others coming from Eric Moloney (2), James Luxton, Dave O'Donovan and John Shine.
UL Bohs now fill the bottom spot, two points behind Old Belvedere and three adrift of Shannon. Their troubles continued when they were well beaten 27-9 by Dolphin at Musgrave Park.
It was an important win for Dolphin as it eases their relegation worries.
John Gleeson and James Cronin scored their tries with the rest of the points coming from Barry Keeshan's boot.
The remaining game in the league saw St Mary's College continue their push up the table with a 25-15 home victory over Garryowen.
Steve Toal-Lennon, Rob Hudson and Gareth Austin scored tries as St Mary's moved up into fifth, while Garryowen dropped from second to third. There were some huge victories in Division 1B, most notably at Stevenson Park where second-placed UCD annihilated Dungannon 84-15.
Unbelievably, they scored 14 tries with three of them coming from wing Sam Coghlan-Murray.
Leaders Ballynahinch were also in top form, demolishing Bruff 59-7 at Kilballyowen Park. They crossed for nine tries with Stuart Morrow getting a brace.
Ballynahinch lead the table by eight points from UCD with Dublin University a point further after beating Buccaneers.
Terenure are on course for promotion from Division 2A after beating Midleton 52-14. They lead Corinthians on points difference, while Barnhall lead the way in 2B after they beat Sligo 17-13 away.
