Milton Keynes Dons moved within one point of relegation rivals Blackpool with a comfortable win.
Izale McLeod put them ahead in the 39th minute with a good left-foot shot after a neat one-two with Wade Small.
Steve Palmer doubled the lead with a header from Nicky Rizzo's cross, only for Blackpool's Scott Taylor to make it 2-1 with an 81st-minute penalty.
But one minute later, Allan Smart pounced on an error from Peter Clarke to make the game safe.
