Mendis nudges Little's left-arm seam off the hip for a single off the first but the second is a bit more hair-raising as De Silva hooks a bouncer worryingly close to short fine leg
Thanks, Tom! You've got to fancy Sri Lanka from here, but a couple of early wickets might change that opinion.
Low-scoring classic, anyone?
Anyway, here come openers Kusal Mendis and Dhananjaya de Silva, with Joshua Little all set to open the bowling..
So Sri Lanka need 129 runs to win at a rate of 6.45 an over. Well within their capabilities you would think - but you never know.
Here to guide you through the chase is the ever-reliable Tim Oscroft.
Ireland batter Harry Tector: "They definitely bowled well. I don't think the pitch was as good as it was in the group stage, but they bowled nicely.
"We are about 20 short of where we want to be. With five to go we were looking to get about 150 but these things happen and we just have to do our best in the second innings."

This feels like a very under-par total.
It's a comedy ending as Simi Singh goes for the scoop again, misses, the throw at the stumps is also off target and Ireland can scramble two.
The smiles on the Sri Lanka players' faces say it all, though. They have bowled superbly and restricted Ireland to 128-8. That does not feel like enough.
That's a good shot. Another single brings Simi Singh back on strike and he plays a lovely scoop shot over short fine leg for four.
Last ball coming up...
The Sri Lanka fans inside the Bellerive Oval are absolutely loving it as Binura Fernando bowls the final over.
After a couple of yorkers he attempts a slower ball that turns into a high full toss that new batter Simi Singh nudges away for a single.

Adair fetched it from wide outside off stump and it was safely taken.
Adair c Chamika b Hasaranga 0 (Ire 118-8)
It's a carbon copy as Chamika Karunaratne takes the catch at deep mid-wicket. Ireland in a huge hole now.
Delany c Chamika b Hasaranga, 9 (Ire 117-7)
That's a hoick high into the leg side after a brief juggle, Chamika takes it at deep midwicket.
All going horribly wrong for Ireland here - that decision to bat has backfired a bit.

Not the batter they wanted to lose in this situation. That could have been hit anywhere but it was a bit 'toey' and went straight to mid off.
Tector c Shanaka b Fernando 45 (Ire 117-6)
Tector goes! It was a wide full toss from Binura Fernando and Tector can only toe-end the ball straight to mid-off.

If you're going to swing, swing hard especially at this part of the game. They have to if they are going to get anywhere near that 140 mark.
Replays of George Dockrell's dismissal showed the ball straightened significantly. It was a superb delivery from Maheesh Theekshana.
Binura Fernando, complete with Stuart Broad-style headband, bowls the 18th over.
He is cursing his luck as new batter Gareth Delany goes for a wild swipe that flies off the edge and loops just over the fielder at short third man.
They all count.

That ball gripped in the surface ever so slightly, probably the first time we have seen that here. It looked like a poor bit of cricket from Dockrell.
Dockrell b Theekshana 14 (Ire 107-5)
Jinxed it!
George Dockrell never really got going and in attempting to open his body and force the ball into the off-side has seen Maheesh Theekshana clip the top of the bails.
Ireland were in trouble at 60-4 when Curtis Campher went for just two.
They have steadied the ship since - but can they push on in the final four overs?

Wanindu Hasaranga's bowling with a round arm and is almost collapsing - it's everything as a bowler you are told not to do.
