RaboDirect PRO12: On-song Leinster score impressive victory over Scarlets

The province's head coach Matt O'Connor reintegrated a number of their international players and a very efficient first half hour at the RDS yielded three tries - one each for Brendan Macken and Jack McGrath as well as a penalty try.

The Scarlets ate into the 22-0 half-time deficit with an opportunist score from Gareth Davies and Gareth Maule added another by the hour mark but Leinster made sure of the bonus point with tries from Eoin Reddan and man-of-the-match Zane Kirchner before a late consolation effort from Scarlets centre Adam Warren.

The Scarlets were first to threaten, with half-backs Aled Thomas and Gareth Davies leading them through a mammoth set of phases as they edged towards the home try-line but Leinster held them at bay and captain Shane Jennings won an eighth-minute penalty slotted home by Ian Madigan.

Kirchner added some zip to an attack on the left before centre Macken evaded Warren's grasp in midfield and darted over in the right corner. Madigan was unable to convert.

Leinster then forced five-metre scrum which forced a couple of penalties and the third collapse led to the awarding of a penalty try.

After Madigan's conversion, the Scarlets looked set to hit back immediately as scrum-half Davies raided through but his pass to the supporting John Barclay was adjudged forward.

Injuries to Martin Moore and Gareth Owen briefly broke up the game's momentum, however the Scarlets were now struggling and Leinster's power up front ground them down again with prop McGrath piling over under the posts. Madigan added the extras.

The visitors - with a reinforced front row containing Romanian international Horatiu Pungea - pressed for an elusive try and they got their reward seven minutes into the second period.

Timani yellow carded

Scrum-half Davies profited from a Jennings knock-on as he scooped up a breaking ball and his momentum took him past Madigan and Reddan to score in the left corner. Thomas sent the conversion to the left and wide and the Scarlets suffered a setback soon after as number eight Sione Timani saw yellow for a foot trip on Lote Tuqiri.

Reynolds did well to tackle his opposite number Fitzgerald into touch to deny Leinster a fourth try and the visitors made it a 10-point game with a terrific breakaway effort.

Barclay scrapped for a ruck ball and Jordan Williams and Warren spearheaded a fine counter-attack which ended with Gareth Davies providing the try-scoring pass for Maule who injured himself as he grounded the ball.

After Thomas supplied the extras and Maule was taken off, Leinster made sure to score before Timani's return.

Sean Cronin's barnstorming run got the hosts into position and Reddan plunged over from a close range ruck, with Madigan sweeping home the touchline conversion.

There was still time for replacement Jimmy Gopperth to break down the left and set up Kirchner for a comfortable finish in the corner, before the Welsh region had the final say as Warren evaded Tuqiri's clutches in injury-time.
