LEE Gregory's fourth goal of the season earned Millwall a vital win at Brighton.
Gregory tucked away one of few clear-cut chances in a scrappy match to move the Lions up to 17th in the Championship table.
The visitors were holding onto their lead for long spells but Danny Shittu marshalled the back four to a hard-earned clean sheet – just a week after Millwall conceded five to Middlesbrough.
It wasn't pretty but the three points were all that mattered for the Lions.
Spaniard Angel Martinez made his first Millwall appearance at the Amex Stadium and his inclusion was one of five changes made by Ian Holloway to the starting XI.
Magaye Gueye, Martyn Woolford, Danny Shittu and Mark Beevers also came into the side as the Lions went with a 4-2-3-1 formation.
Both sides have been on miserable runs of form in recent weeks but Millwall made the markedly better start on the south coast.
After Solly March saw a deflected shot held by David Forde, the Lions took a grip on the early proceedings with some sharp passing and neat interplay.
A clever reverse pass from Martyn Woolford found the run of Gregory inside the box but the striker's snapshot was deflected behind for a corner.
Scott McDonald then fired over the bar from long range after a quickly-taken free kick before successive Scott Malone crosses were scrambled clear by the Seagulls.
But the Lions deservedly took the lead in the 15th minute when Gueye's miss-hit fell kindly to Gregory, who steered his shot across goal and inside the far post.
Brighton's nerves were evident but Millwall failed to ram home their advantage after going in front.
Instead, Sami Hyypia's side edged their way back into the game, with Gary Gardner going close from a free kick and Forde denying Jake Forster-Caskey.
Gardner side-footed over in the 33rd minute before Forde palmed behind Joao Teixeira's drive at his near post.
By the end of the half, the visitors were sitting deeper and deeper inside their own half but they took their 1-0 advantage into the break.
The second period began in a similar fashion, with Brighton on the front foot and looking the more dangerous of the two sides.
Darren Bent, who had been anonymous in the opening 45 minutes, suddenly had two chances in quick succession but shot into the side netting before heading wide.
The Seagulls then carved out their best opportunity so far when Adam Chicksen crossed for March, who was unmarked but fired wide on the half-volley.
At the other end, Gueye's free kick drifted over and Martinez's low drive was pushed away by Stockdale as Millwall finally generated a bit of forward momentum.
Five minutes were added on by the fourth official but the Lions dug deep to clear a flurry of crosses and corners into their box and claim a crucial victory.
