Alex Morris' Under-23 side secured all three points against a strong Sheffield Wednesday outfit on Wednesday afternoon.
The Alex travelled to Sheffield Wednesday's training ground in search of making it four unbeaten and they did just that.
Max Woodcock was awarded the goal after seeing a deflected effort saved by the Wednesday stopper before stabbing home to claim a 1-0 victory for the Reds.
In the opening stages of the game, neither side managed to register any shots on goal and both 'keepers were relatively happy.
Connor Salisbury looked to take the game by the scruff of the neck as he rounded Josh Render before firing his shot just wide of the post.
Tom Booth was then called into action to stop Jayden Onen and Liam Waldock both from range.
Crewe started brightly in the second half, and were rewarded for their efforts in the 56th minute.
Woodcock was the quickest to react to Render's fine save on the goal-line and poked in the opener.
Charlie Finney was inches away from adding to the scoreline only to be denied by the retreating Ryan Galvin.
Wednesday's temperament got the better of them late into the afternoon as they were reduced to nine men.
Onen was shown a straight red for dissent and Jayden Brown followed his teammate into the referee's notebook for a second yellow following a late challenge on the half-way line.
Four unbeaten now for Alex Morris' men and up to fourth in the Professional Development League.
