A late goal from Pascal Struijk condemned Crewe Alexandra Under-23s to a 2-1 defeat at home to Leeds United.
The away side took a first half lead through Jamie Shackleton, who fired in just before half time.
James Jones latched onto a Christian Mbulu header to volley in for the Alex's equaliser.
However, late on, Struijk netted after a Leeds corner to give the side all three points in the Professional Development League.
Crewe: Richards, Johnson, Woodthorpe, Jones, Mbulu, Offord, Dale, Griffiths, Onyeka, Finney, Heath (Lomas).
