Siddal made it back to back wins against Premier Division play off rivals with a 19-16 success over Wath Brow last weekend.
Tries from Craig Sanderson, Tom Garratt and Emerson Newburn – all goaled by Gareth Blackburn – put Siddal in control, with a second half drop goal from Chris Brooke sealing victory.
Having downed Wigan St Patricks a week earlier, the Chevinedge side, who have a blank weekend this week, are now up to fifth, just a point behind Wath Brow.
“It was the second of two very big games for us,” said coach Gareth Greenwood, who takes his team to East Hull a week tomorrow.
“For me, it’s been a bit of a season-defining two weeks.
“If we had not picked up those points, we’d have been down there in eighth or whatever and struggling rather than being right in the mix.
“We seem finally to be getting some form, which I always thought might come as we got into September.
“The holiday season is over and we’re getting some consistency with the selection, which is massive for any side at this level.
“We’ve got 17 good lads at the moment and we’re seeing the benefits of that on the field.”
Ovenden coach Gareth English has said he could still be in joint charge of the side next season as part of a new-look coaching team.
English saw his team conclude a solid Division Two season with a frustrating 32-28 loss at Leigh East last weekend.
The former Keighley and Halifax prop had already announced his intention to stand down because of work commitments, but has now raised the possibility of sharing the job in 2014.
“I’m on shifts, so I can get to training one week, but not the next, which isn’t fair on anyone,” said English.
“I have said to the club that I would carry on with someone else, so we’ll see what happens.
“I think we have consolidated this year, which was a fair achievement given the number of young lads we’ve brought into the side.
“We’re not far away; our biggest loss has been by 16 points or so and we’ll be better again next season.”
