Premier Division leader Waiters Arms thrashed King Cross 7-2 to move six-points clear at the top of the table.
But Waiters have played two games more than second-placed Halifax Hammers, who can close the gap when they play one of their games-in-hand against King Cross on Thursday.
Hollins Holme turned the form book upside down to earn themselves a Shay cup final appearance on Tuesday, May 1 after overcoming favourites Halifax Hammers 3-2 in last weekend’s Halifax FA Sunday Cup semi-final at Calderdale College.
Hollins lost 3-1 at home to Halifax Sunday League title hopefuls Hammers in the Premier Division three days earlier.
Lee Mount, who beat Feathers on penalties in the other semi-final, will be Hollins’ opponents at FC Halifax Town’s home.
Hollins have been in existence for 50 years and they will be looking to repeat their only other major trophy success which came in this competition four years ago.
They beat Hammers 3-2 in the FA Cup final at Brighouse Town in March, 2014.
Hammers drew first blood on Sunday with an early goal and had plenty of possession but the visitors’ compact system kept them at bay.
Two goals from Chris Garbutt in the space of 10 minutes leading up to half time tipped the scales the visitors way.
Andy Butterworth’s cross provided his opener at the back post and Garbutt added a second in similar fashion from Greg Spink’s delivery.
Hammers drew level on the hour with a rocket free-kick from the edge of the box but big Joe Gibson got the winner when he powered a header into the top corner from Spink’s free-kick with 15 minutes left.
The home side continued to see plenty of the ball but Hollins defended well to the final whistle and Parker said all his players had made a full contribution to the success.
Hollins had led through Spink in last Thursday’s game at Calder Holmes but Hammers were level by the interval and then scored two more.
In Division One, leaders Bradshaw were 11-0 winners at Triangle, meaning they are now five points above second-placed Siddal but have played two games more.
There were also away wins for Old Pond, 6-2 at Halifax Amateurs, and Thrum Hall, 5-2 at Halifax Rangers.
In the League Cup, Siddal beat North Bridge 8-1 to book a place in the final against Bradshaw.
Wayne Crossley netted a hat-trick, with goals also coming from Matt Shaw-Burns and Jake Thompson (2), whilst Carlton Balmer and Liam Senior also weighed in.
Bridge fired back through a solitary Sean Byrne strike but were well beaten.
