WILLIAM Lygo struck the only goal as Croesyceiliog won their fifth straight Division Two game to move to just three points off a promotion spot.
Cross-town neighbours Cwmbran Celtic also won 1-0 to move up to seventh in the Division One table, which has Risca United firmly rooted to the bottom after yet another defeat.
In Division Three, high-flying Chepstow Town were held to a 1-0 draw by basement outfit Tredegar Town while another relegation-threatened side, Treowen Stars, earned a point from a similar score against hosts Trefelin.
Croesyceiliog entertained west Walians Garden Village after their playing surface at their Woodland Road home ground had passed a morning inspection.
The Cockerls had previously defeated both Aberbargoed Buds and Dinas Powys 2-1 at home, triumphed 1-0 at Ammanford before posting win number four following an amazing 6-4 scoreline over visting Pontardawe.
However this time only Lygo's sixth league goal of the campaign counted and the outcome took Croesyceiliog onto 26 points with third-placed Pontypridd on 29 following their 4-2 away success at Ammanford.
But it has to be pointed out Pontypridd have played three matches less than Croesyceiliog, who have just 11 fixtures left to complete their 2016-2017 season.
They have a couple of weeks off now before they will bid for a sixth consecutive league victory, when entertaining current fifth-placed side Cwmamman United on Saturday, February 11.
In the only other second-tier game involving a local club, Aberbargoed Buds slipped to a 3-0 home reverse at the hands of Aberdare Town at the Centre of Sporting Excellence in Ystrad Mynach.
It should have been four because besides goals from Rob Blatchford, Elliot Morris and Luke Jones, Aberdare's Warren Jones missed a penalty.
Aberbargoed are still two places and a single point above the drop zone and have a 'must-win' meeting at the same venue against bottom-but-one Swansea-based West End on Saturday.
In the top flight, Celtic relied on an 18th-minute Owen Cook goal to see off Ton Pentre at home, the outcome being their first league clean sheet since the 4-0 home victory over Taffs Well way back on August 27 last year - a gap of 15 league games.
Apart from both sides having a goal disallowed (Josh Bull for Celtic and Sam Small for Ton) and marvellous save from home goalkeeper Lewis Watkins to deny Liam Hutchinson before the break,
this was the type of game to deposit in the memory bank.
Monmouth Town began against hosts Cambrian & Clydach seeking a third win in four, but had to be content with a point from a 1-1 stalemate.
It was a close affair though as the home side only took the lead five minutes from time with Monmouth immediately throwing on substitute Jordan Heales - who levelled matters deep into stoppage time.
Monmouth are not out of the woods because although they head the side in the first relegation spot, Ton Pentre, by three points, they have played as many as five matches more than the Rhondda club.
Risca's woes continued on Friday night, when they went down 3-2 in the capital against Taffs Well.
A victory would have taken them off the bottom above Caldicot Town and Ton Pentre, but despite goals from Nathan Mathias and Seb Haggett - his fifth of the season - the Cuckoos lost out to efforts from Joey Evans (2) and Tim Parker
Chepstow's rise up to sixth place in Division Three meant they were clear favourites to beat off the challenge of bottom-placed Tredegar Town at Larkfield Ground.
And that's exactly how it was panning out as an Adam Wakeley goal appeared to be enough for Chepstow, who gave club debuts to new signings Andrew Evans and Ben Jones.
However up popped Tredegar's leading scorer, Ian Pettit, to grab a last-minute equaliser to earn his team a deserved point.
It was attacking midfielder Pettit's 14th league goal of the season with Wakeley taking his total for four.
Treowen travelled to face league newcomers Trefelin bidding for a win which would have taken them out of the three-strong relegation zone.
But it ended all square and they now trail the team in the first safe spot, not-in-action county rivals Caerleon, by only a single point - and with as many as five matches in hand.
It was a fine display by Treowen with both returning winger David Hurley and Josh Protheroe to the fore as the former set up the latter for the equaliser to cancel out Ryan Morgan's opener for Trefelin.
