Clayton Donaldson hit two goals in two minutes as Crewe claimed a 3-0 win over Wycombe, which ended the Chairboys five-game winning streak.
Shaun Miller completed the scoring with a late strike as the Alex moved into the play-off zone and recorded their third clean sheet on the bounce.
In a goalless first-half, Donaldson should have broken the deadlock minutes before half-time but he clipped the ball wide of keeper Nikki Bull and the post when put through by Luke Murphy.
The excellent Byron Moore hit the crossbar for the Railwaymen with a cross-cum-shot before Donaldson gave Crewe the lead with two goals in quick succession. First he left Winfield for dead before clipping the ball over Nikki Bull in the 71st minute.
Then sixty seconds later he raced onto Danny Shelley's ball and hit a first-time shot low into the bottom corner of the net.
Miller put the icing on the cake for the hosts by side-footing home on the rebound after Lee Bell's 86th-minute shot crashed back off the upright.
