In a ding-dong match, Slaz came out victors with a cleverly deflected goal from Gavin Kaye in the last few minutes.
There never more than one goal in it with Slaz opening the scoring with a short corner strike from skipper Geoff Birkett.
After a reply from Harrogate, Martin Lofthouse pot Slaz back in front with a flick into the corner of the net from another short corner routine – only for Harrogate to hit back again.
Ian Wiper repeated the sequence again with a delightful flick over the keeper.
Harrogate then scored twice to go in front for the first time in the match, but Andy Auty set up Richard Whawell for the equaliser and then Gavin Kaye’s winner sealed it for Slaz.
