However, Brig had to make do with a one-point lead after they were held to a 1-1 draw at Trafford.
The home side came into the match on a run of six league games without defeat, and took an early seventh minute lead through Scott Sephton. But in front of a decent crowd of 351, Regan Linney equalised after 32 minutes for a share of the spoils.
Like Shields, Hyde United have games in hand over Brig due to their cup run, and are third, five points adrift of the leaders, after edging out another of the top six challengers, Ossett Town.
It`s now 13 games unbeaten for the Tigers as, in front of a good crowd of 589, a goal right on the stroke of half-time from Phattharaphol Khamsuk proved decisive.
Scarborough Athletic were looking to move into third place when they travelled to Prescot Cables, who were also looking for a top six spot.
And it was Cables who won to move level on points with Boro. Baba Conte broke the deadlock to give Cables a 55th minute lead that Michael Coulson immediately cancelled out a minute later.
Jordan Southworth restored the home side`s lead 18 minutes from time, and, in front of a fine crowd of 518, Josh Klein-Davies scored the all-important third for Cables six minutes later.
Ossett Town are seventh after a 3-1 Ingfield win over Colne.
Ollie Crankshaw gave the visitors a 10th minute lead that Danny South levelled from the spot after 35 minutes. Liam Owen put Town ahead on the hour-mark and Kai Hancock added a third 10 minutes from the end.
Bottom side Goole AFC were beaten for a fourteenth time – 4-2 at Seel Park by Mossley AFC.
And that, despite taking a first-minute lead through Carl Stewart and a 2-0 lead with a goal from new signing Jorome Slew 19 minutes later. Tom Dean began the Lilywhites comeback three minutes later and Mike Fish equalised three minutes after that.
Just shy of the hour-mark, Caldon Henson made it 3-2 to the home side, with Danny McLaughlin making the points safe on 61 minutes.
Carl Peers bagged a brace for Radcliffe FC by the 38th minute at Stainton Park against Brighouse Town.
But it ended up being in a losing cause as a Tom Haigh double and Rhys Jenkinson turned the game in the visitors` favour in the second half.
Tom Corner was another two-goal man for Tadcaster Albion as they beat Clitheroe 2-1 at home, Corner striking in the 42nd and 62nd minutes, with George West replying two minutes later.
Danny Bartle put Colwyn Bay in front on the half-hour mark at Parkside against Kendal Town but Ben Thomas equalised six minutes before the break and then a Rob Bowman penalty won it for the Mintcakes on 65 minutes.
