Kate Rowan's player ratings: Who stood out and who disappointed in Yokohama? After the thrills and spills of New Zealand versus South Africa in the same stadium the previous evening, this was a rather more prosaic affair beneath the rain in Yokohama. More Soggy Sunday than Super Saturday.
Over to England A great start for Ireland, work to do for Scotland.
That's it from here, but that's not the end of our World Cup offerings today, with England v Tonga kicking off in 15 minutes. You can follow all the action for that, right here.
But the coaches will show us tomorrow what we need to improve on. We came off second best in a lot of areas today. We need to get over that and learn our lessons. That was a dominant, composed display from an Ireland side who were not at full strength, against what was supposed to be their main challenger for top spot in Pool A.
For Scotland, it is a desperately disappointing display that has undone a lot of the optimism going into this tournament. The pressure is now on them to seal second spot in the group, and improve quickly for the clahs with Samoa. Just one minute to see out now. I think both sides will be happy to get off the field now.
There have been 16 missed tackles, 10 handling errors and six turnovers from Scotland. It just has not been good enough today. Finn Russell lines up a crossfield kick but loses his footing and they have to go for touch again.
This time Ireland steal and the pressure evaporates. Hogg will send this into the corner once again. A decent set piece move tries to send McInally down the blindside into the corner, but Ireland are smart to it.
As they try to recycle another handling error - their tenth - gift possesion back to green shirts. Ireland Scotland Tadgh Beirne 70mins: Hogg makes a break as Scotland break the line for the first time, but their attack is stopped, illegally, by Ireland sub Beirne.
He's sent to the bin and won't be back. Can Scotland make it count? Even for the No 1 side in the world, this has been an impressive display. Farrell charges forward deep into the Scotland half.
He's been sensational since coming on. A navy jersey is in an offside position and Ireland have a chance to put another three points on the board and make it a four-score game. Not that it really matters at this stage All the pressure is on Scotland to create something, and they are trying, but it has been a shambolic display from each department of this Scotland team.
A lovely dink kick here, a flick out the back door from Farrell there. It would have been a phemonal try had sub Luke McGrath been able to hold on, instead it's a scrum to Scotland Ireland Scotland Andrew Conway That will be that, then.
A simple try for Conway, who is the beneficiary of yet more uncertainty under the high ball for Scotland. Ryan Wilson this is far from convincing as Murray targets him, and Larmour gets the better of him, the ball bouncing kindly for Conway, who negotiates a few half-hearted tackles before touching down.
Murray misses the conversion. Hogg takes a mark and smashes a spiral kick up to half way. Ireland have the ball back, and the longer this half goes on, the more comfortable they're looking. Ireland get a free kick off the scrum, but Grant Gilchrist decides to attempt to charge it down.
He doesn't and only succeeds in tickling the ball with his fingertips, handing the lineout - which would have been Scotland's - to Ireland. More self-inflicted wounds.
A few patient phases sees the ball moved to the right as dark navy shirt continue to pick and go. It all ends when Barclay can't hold on to the ball, giving Ireland a scrum 10 metres from their own line.
Some signs of promise, though.
They go through nine before, yet again, Hogg puts the grubber through and forces Ireland to take a lineout inside their own The possession is a start, but they need to start making it count.
The ball is recycled to the right, but Hogg puts the ball to boot again, sending it into the Ireland It'll be Ireland ball though, and they've won every lineout so far. A good spell of pressure from the blue shirts sees them put together a few phases, but it all unravels when Taylor drops the ball.
Russell boots the ball away in frustration. It's been that kind of day so far for Scotland.
One promising moment is undone as they fail to look after the ball. Hogg breaks and keeps the ball in hand - sensible in these conditions - but there is no support and Ireland turnover, breaking dangerously down the right flank.
Conway challenges Hogg for the ball in the dead-ball area, but unfairly says Wayne Barnes, and Scotland have a penalty. The rain is now bucketing down too.
This could make things interesting. With Sexton also struggling and relinquishing kicking duties to Murray, it hasn't all been plain sailing for the boys in green. A lot of work to do.
But we've seen some stunning comebacks from this side before. Time for another? It could have been worse for the Scots, with Sean Maitland beaten all ends up by Conway but Henderson knocks on. That is sad to see.
Fraser Brown is on for him, he goes to openside. An interesting call from Townsend. Can it give Scotland any help in getting back into this?
