Blackpool secured bragging rights over relegation-threatened Fylde Coast neighbours Fleetwood with a 1-0 victory.
The Seasiders boosted their hopes of a play-off place thanks to Jake Beesley’s first-half effort and a missed Shayne Lavery penalty at Bloomfield Road.
Neil Critchley’s side are three points off the top six.
Beesley nodded home the only goal of the game in the 22nd minute as he got on the end of CJ Hamilton’s fine cross.
Jay Lynch denied the hosts two minutes later when he kept out George Byers’ stinging strike.
After the break, Byers squandered a great chance when he fired wide before Beesley also fluffed his lines.
Lavery, who was brought down inside the box, saw his 77th-minute penalty superbly saved by Lynch.
Charlie Adam’s side failed to take advantage to rescue a point in their survival fight as Fleetwood sit six points off safety with just four games left.
