AFC Wimbledon secured a spot in the League Two play-offs with a 1-0 victory over Grimsby at Blundell Park, denying their opponents a chance at the play-offs.
Johnnie Jackson's team clinched the crucial three points thanks to Sam Hutchinson's goal in the second half, ensuring their season would continue in the play-offs.
Despite Grimsby's early push for a goal, with skipper Danny Rose going close with a header, Wimbledon focused on defense in the first half without registering a shot on target.
After the break, Wimbledon upped the ante and Hutchinson capitalized on a rebound in the 53rd minute to break the deadlock.
Although Marcus Browne had an opportunity to double the lead, he missed the target with his shot in the second half.
Grimsby tried to respond, but Justin Obikwu's effort was saved as Wimbledon held on for a crucial win that defined their season.
