Replacement centre Chris Farrell was the star of the show as a professional Ireland recorded a bonus point win against a poor Scotland in Yokohama.
the Munster centre and James Ryan were the most impressive Irish on show as the Scots were bullied in this Pool A opener.
Jordan Larmour 7
Telling how quick he was to support Luke McGrath in the tackle in last quarter with a clear out. A no-nonsense performance. Good in the air early on and made a superb break that had Scotland scampering on 10 minutes. Great work in tackle ended a menacing Sean Maitland run and won Ireland a penalty. Overall his positioning in defence was reassuring
Andrew Conway 7
Rewarded for a fine showing with the bonus point try after good work by Larmour. Dropped a gimme box kick to concede an attacking scrum at midway point of first half. Great hack and chase against Russell Hogg, earned five-metre scrum with tackle. Third try a result. A lively figure on the flank and will give Joe Schmidt pause for thought once Keith earls returns to full fitness.
Garry Ringrose 6
Did not put a foot wrong in a low key outing. Couple of big tackles early on and was quick off the line to force Scotland's backs into quicker action than they would like. Nothing of note on attacking side.
Bundee Aki 5
A menace in midfield, with or without the ball. Looked in great form and condition, unfortunately did not reappear after a HIA on 21st minute.
Jacob Stockdale 7
Another of the back three to drop an easy ball, backpedaling from a Finn Russell kick the Ulster winger kicked the ball into touch. Immense, prejudged tackle on Stuart Hogg ended a promising Scotland attack in devastating fashion. replicated in closing stages when down to 14. A few trademark chip and runs. However, when conditions allowed in the first half, he looked very threatening.
Jonathan Sexton 6
Took his fair share of punishment but looked in control behind a dominant pack in the first half. Handed over kicking responsibilities to Conor Murray after successfully kicking one of the first two conversions. Noticeable how little ball he handled after the break.
Conor Murray 7
When Sexton was being minded in the second half he took control of the match and showed great composure, launching the Garryowen for fourth try. Early blocked down kick put Ireland under pressure. Kicked the third conversion attempt flawlessly.
Cian Healy 7
His power was central to first try and his power was key to a dominant scrum display. Looks in peak physical condition.
Rory Best 7
Played 80 minutes at 37. Lineout an attacking weapon again in the early stages and the captain was the man with the ball in the maul and showed incredible athleticism to spin over the line for Ireland's second try. Several lineout miscommunications later in the game will be a worry.
Tadhg Furlong 7
Scored the third try with a typically bullish run. His primary role of locking the scrum was close to perfect too. Hard to judge after such a weak Scottish challenge but could be returning to the form that saw him dominate on the Lions Tour in 2017.
Iain Henderson 6
Superb line break on Scottish 22 was platform for James Ryan's try. Made the most metres in the pack after CJ Stander.
James Ryan 8
Scored the opening try with a short drive over the line. Delivered what we now consider standard for him. A force around the tackle area, calling the lineout and always showing for work. Approaching Sexton as Ireland's most important player.
Peter O'Mahony 5
Departed far earlier than he or Ireland would have liked. A HIA required after a short but committed outing on 27 minutes
Josh van der Flier 7
Good tackling a given from the Leinster flanker, who was the pest in contact that Ireland need. He will be central to any quarter-final contest.
CJ Stander 7
Great, quick run off the 5-metre scrum set platform for third try. Almost ran in a try of his own from distance but more dynamic overall. Back to making metres with ball in hand - led the way in the pack with 43 metres. Finished up in the second row after Tadhg Beirne's sin-binning.
Chris Farrell for Aki (HIA) 8
From almost missing the plane to man of the match. An audacious behind the back pass for Luke McGrath would have lead to a contender for try of the tournament had the move come off. Later ran a lovely line that almost brought a try for Stockdale. Good tackling in the midfield, one of which led to Andrew Conway's breakaway ahead of third try. "This guy is a monster," says Donal Lenihan. Hard to argue.
Jack Conan for Peter O'Mahony (HIA, 27 minutes) 7
Moved to 8 and played a fine game from defensive perspective, topping the tackle count on 14 with James Ryan. Tackled his heart out but will hope for more attacking opportunities in future outings.
Andrew Porter for Tadhg Furlong (50 mins) 6
Scrum remained a solid platform for final 30 minutes, even winning one against the head.
Dave Kilcoyne for Cian Healy (50 mins) 6
Will be delighted by winning scrum against the head. Will have more opportunities to display his running abilities.
Jack Carty for Sexton (58 mins) 6
Found touch early and then played a very clever chip kick, which is becoming something of a trademark. Had to make some tackles and did so.
Tadhg Beirne for Henderson (58 mins) 4
That blue scrum cap was prominent around the tackle area, until he got a 69th minute yellow card for killing the ball playing it off his feet.
Luke McGrath for Murray (58 mins) 5
Got into the mix quickly but his pass to Stockdale was not to hand.
Niall Scannell for Van Der Flier (74 mins) 5
Played in the back-row. Will hope for some minutes at hooker before too long.
