Sean Longstaff's second-half strike was enough to earn Blackpool a seventh successive home league win with a 1-0 victory over 10-man AFC Wimbledon.
The Seasiders had the first shot on target as Kyle Vassell's curling effort from 20 yards was well held by George Long after 14 minutes.
And Long was in action again five minutes later, keeping out Jimmy Ryan's deflected free-kick.
Visiting striker Cody McDonald produced the first moment of real quality on the stroke of half-time, turning sharply to go clear through on goal, but he was denied one-on-one by Ryan Allsop.
Longstaff put Blackpool ahead on 52 minutes, notching his fourth goal in as many games, as he jinked past three defenders before firing low into the bottom corner from 18 yards.
And things got worse for Wimbledon just over a minute later as Jimmy Abdou received a straight red card for a two-footed tackle on Callum Cooke.
Cooke, Nathan Delfouneso and Vassell all had golden chances to widen the margin, but Blackpool saw it out to go four league games unbeaten.
