Leinster completed a near perfect season in the Aviva Stadium this evening with an eight-point victory over Scarlets in a free-scoring Pro 14 final.
In triumphing on a scoreline of 40-32, Leinster became the first team to win the Champions Cup and the Pro 14 title - in any of its guises - in a single season.
It was also the final game in a Leinster jersey for their veteran great Isa Nacewa who left the field after 20 minutes to a prolonged standing ovation having picked up an injury.
After a try-less first half hour in which Johnny Sexton and Leigh Halfpenny traded kicks, lock Devin Toner forced his way over the line from close range after Leinster carried the ball remorselessly through several phases.
This left Leinster leading 14-6 but this cushion was short-lived as Scarlets winger Johnny NcNicholl snaffled a try from the next attack.
Leinster led 14-11 as the clock passed the 40 minute mark and it looked like they would have a relatively paltry lead to boast for all their first half dominance.
However, on the stroke of half-time, Scarlets indiscipline helped them gain a line-out five metres out. From the resultant line-out maul, McGrath fed the excellent Sexton who popped a pass to James Lowe and the Kiwi winger dived over in the corner to leave the score at 21-11 at the break.
Scarlets were entirely helpless against the Leinster lineout maul throughout the game and Sean Cronin scored a try from an identical situation minutes into the second half.
Then followed the moment of the game as Jordan Larmour collected a Scarlets grubber kick near the touchline in his own half. He booted the ball forward and out-paced everyone in his vicinity, speeding onto the ball ahead of the leaden-footed Scarlets defenders.
He scooped up the ball skilfully on the run and dived over for Leinster's score of the match.
Johnny McNicholl scored in the corner to provide some respite but Leinster worked a fifth through some Joey Carbery brilliance in the middle of the pitch. The replacement out-half's swivel of the hips and break ultimately created a score for Jack Conan who trotted under the posts.
This left the score at 40-18 and the crowd were in celebratory mood entering the final ten minutes. Scarlets manufactured a successful drive for scoreboard respectability in the final five minutes as, first Verner Kruger, and then hat-trick man Johnny McNicholl scored tries for the Welsh side - the second of which was after a magnificent attack from their own try-line in over-time.
But the home side's victory was long settled by then and, after Halfpenny's conversion, the celebrations could begin in earnest.
