Craig Ronaldson opened the scoring for Lansdowne with a penalty in the fifth minute. Five minutes later Foster Horan gathered a Cork Con dropped ball and broke from inside his own half to touch down in the left corner. Ronaldson added the extras.
An injury to Cork Constitution Flanker, Brian O' Hara halted play for a number of minutes as he was replaced by Brian Vaughan. Not long after play resumed, Lansdowne missed the chance to extend their lead when a Ronaldson penalty fell wide.
The visitors continued to heap pressure on the Cork Con defence and when Ferdia Doherty found space in the centre, Ron Boucher was there in support to touch down just right of the posts. Ronaldson slotted the conversion. The closing moments of the half saw the out-half cross the whitewash for a try , which converted took the league leaders into the break with a comfortable 0-24 lead.
Lansdowne extended the gap early in the half with a penalty in front of the posts. Five minutes later, Tadgh Beirne touched down for the all important fourth try which was converted by Ronaldson.
The home side were reduced to fourteen when Andrew O' Driscoll was shown yellow ten minutes into the half. Ronaldson missed his second penalty of the day when his long-range kick fell just wide.
Similar to last week Con sprung to life in the closing stages of the game and full-back Daragh Lyons was unlucky when he knocked on an intercepted pass on the half way line. The Cork side worked their way into the twenty two and after a series of drives, Captain Gerry Hurley crossed the line in the left corner to register their first points of the day, the conversion courtesy of Johnny Holland. Con continued to attack in the final moments and were rewarded when Cathal O' Flaherty got over the line in the opposite corner. A further conversion from Holland reduced the gap to 14-34 on the final whistle.
The bonus point win takes the leaders twelve points clear at the summit.

Young Munster occupied second spot heading into their game away to Clontarf today. However, a 35-10 defeat at Castle Avenue saw them slip two places into fourth.
Tries either side of the break from Shane O' Leary and Colin Liston were not enough as Clontarf secured a bonus point victory moving them up to third place, a point above the Limerick side.

A last minute 20-18 defeat for Dolphin away to St. Mary's College at Templeville Road saw them drop four points behind their rivals today with their game in hand against Young Munster yet to be played.
Dolphin took a 10-3 lead into the break after Harry Fleming blocked down a St. Mary's clearance to score the first try of the afternoon and Barry Keeshan kicked a further five points. While Gavin Dunne kicked a penalty for St. Mary's.
The in form Gavin Dunne reduced the gap with a well-kicked penalty early in the second half. But the visitors responded with a try from Munster Academy player, Cian Bohane. Dunne and Keeshan exchanged penalties, while the Dolphin out-half also slotted a drop goal between the posts. The Cork side lead 18-12 heading into the final stages of the game. However, a Matthew D'Arcy try following a block down of a Barry Keeshan clearence saw him over the line. With a point between them, the home side were awarded a penalty inside the twenty two. Dunne was on target to secure the win for the defending champions.

At the bottom end of the table Shannon secured only their third win of the season with a 28-17 victory at home to Old Belvedere. A vital win which takes them within two points of second from bottom, U.L. Bohemian after they were defeated 38-3 by Garryowen in Friday night's game at Dooradoyle.
Shannon romped into a 17-0 half time lead and looked to be in cruise control and on their way to their best win of what has been a pretty poor campaign.
They welcomed back Munster star Niall Ronan who got a late, late, try to deny a spirited Old Belvedere even a bonus point and they got no reward for battling back to make it 17-17.
They might have increased the mounting Shannon troubles but Josh Glynnn was wide with a penalty effort. After that let-off Shannon turned on the style in an amazing final six minutes.
Tadhg Bennett dropped a goal to restore Shannon's lead and then Guerin landed a penalty before Ronan's touchdown for the late try with the conversion going wide off the upright.
Guerin put Shannon in front after eight minutes and he was inches wide with another effort. A prop from each side was sin binned during which period Shannon had their first try when James Loxton finished off a fine movement. Bennett converted to make it 10-0 and when a second Belvedere forward was binned the visitors had only thirteen on duty for a brief few minutes. During that time Richie Mullane raced over and Bennett's conversion made it 17-0.
If Shannon thought they were in for a stroll around Thomond Park in the second half Old Belvedere had other ideas.
Jonathan Slattery and Josh Eden-Whatiri both had close in tries which Glynn conveted and he also kicked a penalty. Suddenly it was all square.
But Shannon have always been known for their spirit and they finished powerfully for a precious win.
Scorers: Shannon: Tries: James Loxton, Richie Mullane, Niall Ronan; Cons: Tadhg Bennett 2: Pens: Rob Guerin 2; Drop: Tadhg Bennett Old Belvedere: Tries: Jonathan Slattery, Josh Eden-Whatiri; Cons: Josh Glynn 2; Pen: Josh Glynn
