Andy Waterworth's goal was enough to see Linfield all but secure their 53rd league title by edging out Ballymena United 1-0 at the Showgrounds on Friday evening.
They're now 12 points clear at the top of the table with four games left and with a goal difference 19 better than Ballymena. A draw with Crusaders at Windsor Park next weekend and it will be officially over.
It was a case of de ja vu for the hosts, who once again couldn't make their chances count against the Blues as the visitors showed their clinical edge at the other end.
Waterworth's 17th league goal of the seasson arrived just seconds into the second half as he fired a first-time shot into the bottom corner to punish the Braidmen's missed chances.
Ballymena's Johnny McMurray managed to force the first shot on target just 15 seconds into the game and, while it did little to trouble Gareth Deane, the Linfield man was the first of the goalkeepers breathing a sigh of relief soon after.
That was when McMurray managed to tee up strike partner Adam Lecky, but pressure from Daniel Kearns forced the former Ballinamallard man to blast over.
It had been a positive start from the hosts and that continued after Kofi Balmer did well to put off Linfield's Joel Cooper at the other end.

Linfield have now kept 25 clean sheets this season but required help from the crossbar when Balmer crashed a half-volley at goal soon after.
Deane was forced into more work of his own when he had to stop Andy McGrory's free-kick finding the top corner.
When you're on top against Linfield, as Ballymena know well from the League Cup final, you had best score.
And the Blues proved why once again through, guess who, Andy Waterworth just 45 seconds into the second half. Cooper found the forward on the right side of the box and, not needing a second invitation, he swivelled and fired a first-time shot across United keeper Ross Glendinning into the bottom corner.
Ballymena got back on the front foot soon after but McGrory was again denied after the midfielder had been teed up by Lecky.
Waterworth tried to add a second in injury-time but even though his volley flew over the bar, it was his night yet again as the goal-scorer extraordinaire delivered another crucial goal for Linfield.
The Blues host Crusaders on Saturday, April 13, when they can officially kick-off their 53rd league title party.
