Nahki Wells scored a hat-trick as Bradford ended their poor away run with a comfortable victory at Northampton.
Wells rounded Neal Kitson to finish with ease early on and shortly before the break he netted with an overhead kick from James Hanson's header.
Cobblers captain Clarke Carlisle pulled one back soon after the restart, forcing the ball home from close range after City failed to clear a corner.
But straight from the kick-off a deft lob completed Wells' hat-trick.
VIEWS FROM THE DRESSING ROOM
Northampton Town manager Aidy Boothroyd told BBC Radio Northampton:
"They defended much better than we did. We gave them goals. They outfought us today and that sickens me.
"We got outworked, we got bullied - and I don't mean that disrespectfully to Bradford.
"I was really disappointed with that because we looked like a team that think they are going home for the summer."
Bradford City manager Phil Parkinson told BBC Radio Leeds:
"The intensity of our display today was absolutely tremendous. We couldn't come here today waiting to concede and then start playing.
"We had to play from the first whistle to win this game and I thought we were right on the money all over the pitch and we deserved the win.
"We said let's have a group of players who will run themselves into the ground to get this result."
