Harrogate survived a lightning start and threatening finish by Otley to win a hard-fought derby 20-10.
Solid ball retention, good handling and astute kicking from hand proved key for the visitors for whom captain Jacob Brady made his 150th appearance and proved a power in the loose.
Otley soon struck, winning a lineout for centre Michael Coady to breach the defence, scrum-half Stephen Depledge converting before adding a penalty.
It was 20 minutes into the game before Harrogate struck, fly-half Callum Irvine fastening onto a loose ball and racing to the posts for full-back Joe Rowntree to convert before making it 10-10 with a penalty.
On 61 minutes, Rowntree put Harrogate ahead with a penalty and he was on the mark to convert a try from Brady 10 minutes later.
Otley pressed but ran a penalty instead of going for goal which could have gained them a point.
A five-try second half romp helped Huddersfield to a 37-3 home win over Leicester Lions.
In a tense first half, against a side three places above them, Huddersfield took a 5-0 lead with a try from full-back Elliot Hodgson before the visitors hit back with a penalty. Fly-half Chris Bell’s penalty made it 8-3 at the interval before the blue touch paper was lit.
Leicester were forced on to the back foot when outside centre Alex Batty went over and Bell converted.
Eight minutes later, right winger Tom Hodson scored out wide and that was followed by two further unconverted tries from second-row Austin Thompson and No 8 Nick Sharp, making the lead 27 points.
In the closing minutes, there was time for a neatly book-ended performance when Hodgson crossed again for his brace and Bell finished things off with the conversion.
