Joakim Lagergren is not letting up.

He wallops another glorious drive down the fairway.

Rory McIlroy blinks! He loses his drive to the right and it gets caught up in the rough.

McIlroy and Lagergren hop back into their buggies and head back to the 18th tee.

However, there's going to be a pin change, so it'll be a different challenge for their approach shots.

In it goes!

Clutch.

On they go...

Lagergren has a pressure-packed tiddler to extend the play-off...

Rory's first. It's actually sneaked past a bit longer than I thought.

Holes it!

Asks the question of the Swede...

Another bold effort!

It misses on the right and Lagergren's not finished yet either.

Now they're going to measure their putts to see who goes first.

Oh the drama.

Joakim Lagergren has a putt to win the Irish Open.

What has he learned from McIlroy's putt on the first play-off hole?

Here he goes.

It's a big swing with the putter.

Good pace on it! It misses on the right and settles about three or four feet behind the cup.

That's not dead.

McIlroy has 53 feet.

His lag putting is usually exceptional but under this pressure it's going to be a big ask, even for him.

Hand comes off the club!

McIlroy's chunked it and his ball comes up way short.

That's a tough two-putt.

Advantage Lagergren...

It'll be Lagergren to go first this time.

He has a six-iron in his hands. It's another great effort and he's pretty much where McIlroy was on the first play-off hole.

Over to Rory...

Here we go again.

Joakim Lagergren up first again. It lands in the rough but kicks to the left and into the middle of the fairway.

Pressure back on McIlroy.

He likes it. Yep, that's way down there.

Lagergren taps in and the play-off continues.

They'll go back to the 18th tee.

Can he do it again?

Ohhh! It just misses on the right. A good putt but that's a four.

It is indeed Joakim Lagergren to go first.

How aggressive will he be?

Here it comes...it looks good, but just misses on the left. Great effort.

McIlroy has a putt for the win.

Decent reply from the Swede. A bit on the short side and it looks like he'll be putting first for his eagle.

That ain't no bad thing in a play-off.

McIlroy has 211 yards in for his second, slightly longer than what he had in regulation.

Wind at his back.

Fine effort! What's that, about 20-25 feet to the right of the pin.

What can Lagergren muster in response?

Tell you what, the scenes at the K Club are whetting the appetite for the Ryder Cup.

Electric atmosphere.

Only three weeks to go.

Joakim Lagergren, who kept himself loose on the range while the final groups finished, rips his drive down 18.

Rory McIlroy steps up. Fairway found.

So, we have a play-off coming up between Rory McIlroy and Joakim Lagergren.

Who's going to win?

Thumbs up for McIlroy, down for Lagergren.
