Pinchbeck United and Deeping Rangers Reserves booked PFA Senior Cup quarter-final places – but Langtoft United and Moulton Harrox were knocked out.
Oliver Maltby (2), Ryan Leggett and Mark Lovelace were on target as Pinchbeck beat Leverington Sports 4-1.
In the last eight they will face Netherton United who thrashed Langtoft.
Having already been knocked out of one cup by Netherton this season, and having also lost both league encounters, the Vikings were hopeful of finally getting the better of their hosts.
But thoughts of a winning start to 2015 were quickly dispelled as Netherton swept into a 5-0 lead. Two late goals from Dan Evans and Ben Porter were consolations.
Manager Phil Gadsby said: “We got hammered and it should have been about eight. You could tell we hadn’t played for a month!
“We deserved nothing from the game and if we play like that for the second half of the season, we’ll get sucked into a relegation battle.”
Deeping Reserves edged out Thorney 4-3 thanks to doubles by Matt Sparrow and Sam Thompson. They will be at home to Wisbech Town Reserves in the quarter-final.
Ryan Wheeler scored for Moulton Harrox who lost 2-1 at home to Premier Division leaders Coates Athletic.
Saturday’s disappointment for Langtoft was compounded as their reserves went down 4-1 at A15 rivals Baston in the PFA Challenge Cup.
Scott Collins, Daniel Pick, Troy Waters and Jimmy Younghusband scored for Baston with Tony Wooding replying.
Ashton Capes (3) and Michael Smith (2) secured Crowland Town Reserves’ 5-1 home win over Sutton Bridge United who replied through Ben Partridge.
Tydd St Mary won 3-0 at Ryhall United Reserves in the Peterborough & District League’s Division Three with goals from Daniel Chapman, Michael Ocock and Joshua Slator.
