It's all over at Windsor Park. All to play for at Oriel Park on Monday night.
Daniel Kelly levels the score with a clinical finish after 51 minutes.
Dean Jarvis clips a pass through the Linfield defence and Kelly does well to control the ball and coolly slot past Deane and into the bottom corner.
A fine finish.
Flores comes agonisingly close to finding the equaliser as his curling left-footer from 25 yards just skims past Deane's right-hand post.
Shayne Lavery's eighth-minute strike sees Linfield a goal to the good at the break.
It hasn't been pulse-racing stuff, it must be said, but Lavery's moment of quality was enough to delight the Linfield fans inside Windsor Park.
Great chance for Linfield to double their lead. Matthew Clarke surges forward and feeds Joel Cooper. He's been in form, so it's safe to assume he'll be disappointed after lashing his shot into the side-netting as Lavery and Kirk Millar waited in the centre.
Not much in the way of goalmouth action since Deane's save to deny Boyle.
Subdued game, it must be said.
Deane produces an excellent reaction save to tip Boyle's bullet header onto the crossbar from Dundalk's corner.
That's the closest the visitors have come. Impressive goalkeeping.
Jordan Flores lets rip from distance but Gareth Deane is happy to watch as it flies wide. The Linfield goalkeeper hasn't had much to do in the opening 25 minutes.
The hosts look very good on the ball, passing it with purpose and precision.
Dundalk clearly pose a considerable threat going forward, however. There have been a few glimpses already, with Patrick Hoban having already dropped into a couple of dangerous positions.
Shayne Lavery rifles home the opener after eight minutes!
Jamie Mulgrew pokes a neat ball through and the young striker drops his left shoulder to beat Andy Boyle and unleashes an unstoppable strike beyond Gary Rogers and into the Dundalk keeper's bottom left-hand corner.
We're under way at Windsor Park.
Strong line-ups for both sides. This should be an entertaining game!Copyright: BBC Sport
