Goals from Jon Guthrie and Sam Hoskins had Cobblers ahead after 50 minutes before everything went wrong, with Harry McKirdy scoring four times for the ruthless hosts. Here are our player ratings...
9. Sam Hoskins
Great touch and finish to bring Cobblers level and was close to a second when poking over. Now has seven league goals for the season and remains on course for his best most prolific return in claret... 7
10. Paul Lewis
Saw a good chance go begging when his shot was blocked and did some good work in the free role. Has an especially happy knack for winning free-kicks which, with Pinnock around, can be hugely beneficial for the team, as the second goal proved... 6
11. Danny Rose
Pressed well from the front as Swindon persisted with trying to pass out of defence, a tactic that often got them into trouble. Unfortunately wasn't able to capitalise... 6
12. Nicke Kabamba
A little more height or power on his header and Cobblers would have had one back during the crazy 15-minute spell after half-time... 6
