League One Blackpool are out of the Capital One Cup after slumping to a 3-0 defeat at Northampton Town.

The hosts threatened throughout the opening exchanges, with Sam Hoskins hitting the post before Dominic Calvert-Lewin headed against the bar.

Northampton finally took one of their chances as David Buchanan teed up Chris Hackett, who steered his shot low past Kyle Letheren.

Within minutes, Town added a second as Calvert-Lewin atoned for his earlier miss by slotting past the Tangerines keeper.

On 32 minutes, Blackpool's League Cup campaign appeared to be in tatters as Hoskins scored his first goal for Northampton.

Neil McDonald's side showed little in attack, failing to register a shot on target in the first 60 minutes of the tie.

Town almost added insult to injury as Letheren first kept out substitute John-Joe O'Toole before saving from another Calvert-Lewin effort.

Connor Oliver and Liverpool loanee Lloyd Jones forced late saves out of Ryan Clarke, but it was all too little, too late as Northampton progress to round two.
