Didn't we knock them out twice at their place, 2012 (Waterhouse's two second half tries) and 2018 (Lineham's match winner) and at the HJ in 2016?

Yes, I remember that, but I think it was a 9s Competition not 7 A-Side.

I was asking about a 13 A-Side knock-out competition final, I can`t remember one after the Lancashire Cup Final that I related to.

I'm pretty sure we've won 6 of the last 7 knock out / play off games against St Helens...

I seem to recall they beat us at the HJ in a playoff eliminator by a Danny Richardson drop goal that hit the bar and went over? May have been about 5 years ago now i cannot remember.

I think that was a normal league game near the end of the season wasn't it?

Could well have been TBH. I just recall it having a playoff kind of occasion to it.
