Player of the Match Jack Conan’s second-half try was the key to Leinster Rugby completing their fourth Guinness PRO14 title success in a row.

Conan barged over from close range in the opening moments of the second half with the game locked at six points apiece.

A crucial score, it would be the only five-pointer of the game as the holders would keep firm for a 10-point win.

Play was called back for Ross Byrne to shoot the opening points when Peter O’Mahony went off his feet in the fourth minute.

Niall Scannell lost his feet for Byrne to double the advantage in the 12th minute as scoring opportunities began to look scarce.

A tackle by Jean Kleyn on Cian Healy tempted Rhys Ruddock to enter the ruck from the side for Joey Carbery to make it 6-3 just a couple of moments later.

Munster’s commitment to compete at the breakdown was reflected in Damian De Allende forcing a penalty out of Hugo Keenan.

The ferocity of the exchanges was fierce, Leinster shepherding their guests across the pitch until Chris Farrell’s ball flew beyond Keith Earls.

The home lineout was working well and the backs engineered space for Jordan Larmour on the right where Mike Haley shut down the attack.

Scannell’s accurate throw to O’Mahony generated a striking maul. De Allende fended Henshaw and Rory O’Loughlin to threaten a breakthrough before Dave Kearney stole the ball in contact.

Munster came again. Andrew Conway chipped over the top. Keenan secured the bouncing ball and Luke McGrath cleared effectively.

Then, Rónan Kelleher burst up the shortside from a lineout. Andrew Porter piled forward. Farrell snagged Byrne. O’Loughlin couldn’t connect with Larmour but a lineout was salvaged after Earls’ quick restart was botched.

Robbie Henshaw took McGrath’s delivery on the move. Scott Fardy took the next ball to power through Carbery, Gavin Coombes and CJ Stander holding the second row up over the line.

Scrum five. Conor Murray snared Conan at the base and Byrne was forced back into traffic.

Significant carries from Josh van der Flier, that man Henshaw and Porter came to nothing as Leinster’s running lines led to obstruction due to crossing.

Kearney and Keenan had to be glue-like in their handling of high balls. Van der Flier got his hands free for an offload to Keenan, the full back flying for 30 metres to find Henshaw on his shoulder.

It looked odds-on for the first try before Earls abandoned the wing to shoot inside and intercept.

Leinster looked to launch their next attack when Stander stepped in to poach a penalty, Murray going close from just inside his half.

Coombes barrelling run put Munster in behind the first line of defence, the home men recovering well enough to keep Earls off the floor for a turnover.

Then, Larmour was penalised for not releasing the ball from Murray’s tackle, Carbery’s kick coming back off the right upright, but he soon levelled it up on the stroke of half-time.

It was all to play for in the second-half, Haley providing Munster momentum from an expert take of a high ball.

When Kleyn spilled possession, the Leinster front row squeezed out a scrum penalty and Byrne targeted a lineout on the 22.

Kelleher found Ruddock, Henshaw sped into a gap, McGrath fed the hard-charging Conan ahead of a bout of close-quarter combat. For a second time, Munster held up, Conan unable to ground the ball at the posts.

But, the No 8 was off the back in a hurry. Ruddock had a go. Porter too. Finally, Conan breached the barrier to get the game’s pivotal score.

After the restart, Ruddock, Healy, Keenan all impacted the gain line and Byrne was taken high by Murray for a penalty which Leinster opted to run.

Leinster were patient in how they operated, new props Tadhg Furlong and Ed Byrne extracting a scrum penalty in the 56th minute, Ross Byrne missing the posts, his first wayward attempt in this year’s PRO14.

On a rare visit inside Leinster’s 22, Ryan Baird ripped the ball away from Stander, Ruddock side-stepped the first man up and Farrell lost McGrath’s garryowen forward.

Conan then picked off a Murray kick for a 20-metre gain. However, the Munster forwards had not retreated and Byrne slotted a superb penalty from the right for a 10-point lead in the 70th minute.

It was a long way back from there for Munster as the champions continued to kick long.

Henshaw nailed Farrell in the backfield and Craig Casey kicked to touch on the full to concede vital ground as the minutes slipped by.

Jamison Gibson-Park chipped ahead for Keenan to corral Conway. Munster just couldn’t escape their 22.

Then, O’Loughlin snatched a loose ball. Larmour’s dancing feet took play to five metres out and the forwards closed it out from there for the province’s eighth league title.
