Aron Sasu scored four times as AFC Wimbledon knocked League One leaders Cardiff City out of the EFL Trophy in a 5-1 win in the Welsh capital.
The Dons' first came just before the half-hour mark as winger Sasu outmuscled Cardiff's Dylan Lawlor before slotting the ball past Matthew Turner's near post.
Sasu doubled his tally 40 seconds into the second-half, after his low drive from the edge of the box flew into the bottom corner.
The Dons soon struck again as an in-swinging corner fell to Omar Bugiel's head at the back post.
Wimbledon academy product Sasu did not have to wait long to complete his hat-trick, with another low shot from the edge of the box.
Sasu, who had only found the net once in his first 75 professional appearances before today, scored his fourth of the game with 15 minutes to go, getting on the end of Steve Seddon's cross.
The League One hit back late in the game when 19-year-old Luey Giles scored a free-kick for his first ever professional goal.
Despite dominating the possession the Bluebirds struggled to create chances with Wimbledon's physicality too much for the hosts' young squad at Cardiff City Stadium.
