Dolphin showed further glimpses of their resurgent form as they ran out 15-points winners, moving into fourth place in the table in the process.

Out-half Barry Keeshan kicked them into an early lead before missing a drop goal and a difficult long range penalty.

But two quick-fire tries from full-back Eamon Mills and flanker Rob O’Herlihy significantly strengthened the Corkmen’s hand, by the end of the first quarter.

Shannon came more into it approaching half-time, scrum half Rob Guerin slotting two penalties either side of an unconverted try from lock Fergal Walsh.

Munster’s Danny Barnes, playing at outside centre for the hosts, saw yellow before the break. A third successful penalty from Guerin cut the gap to 15-14.

But from there on in, Dolphin had the better of the play. Welsh lock Chris Rowe broke through for a seven-pointer and Keeshan added another penalty.

Guerin answered back with his fourth penalty but Shannon could not take advantage of James Cronin’s sin-binning.

Dolphin had the final say with in-form winger James Kiernan grabbing the bonus point score with his second try in as many games.
