Luke Garbutt's 19th minute strike broke the deadlock before Jerry Yates completed a comfortable victory with two late goals. Here are our player ratings from Northampton's final home game of the season...
9. Sam Hoskins
Frustrating afternoon. Snatched at a couple of half chances and wasteful in possession... 4.5
10. Mickel Miller
Once again he was the man who threatened most for the Cobblers. Several darting runs and inviting crosses deserved better but his team-mates couldn't capitalise. Town might still be in the fight had he played more games... 7 CHRON STAR MAN
11. Alex Jones
Wasted a one-on-one chance for the second week in a row, though this time he was unlucky to lose his footing with only Maxwell to beat. Easily beaten to the ball in the build-up to Blackpool's opener and withdrawn at half-time... 4.5
12. Michael Harriman
Some excellent defending at left-back kept Cobblers within touching distance of Blackpool for most of the contest... 6.5
