Three in a row for King Kenny's KidsCrewe Alexandra Under 18's won their third match on the trot after triumphing 1-0 at Barnsley.
Previous 3-0 and 2-0 victories over Hull and Sheffield United respectively also represent a full-house of clean sheets for goalkeeper Kieran Harrison too.
Lunt fielded a strong side for the trip to The Tykes and took the lead early on as Callum Ainley made it four goals in three games as his crossed free-kick sailed past everyone and into the net.
The Alex continued to dominate the game, but Barnsley put 11 men behind the ball and frustrated Lunt's side but never looked threatening at the other end, resulting in a comfortable victory.
Crewe: Harrison, Quinn, Wilkinson, Dowsett, Morgan, Lowrey, Pickering, Ainley, Whalley, Neal, Dale
