- Son Heung-Min (10')
- Harry Kane (79')
- Lewis Dunk (34')
Brighton were by far the better side and had two goals ruled out although the biggest talking point until Kane's 79th-minute winner was an altercation between Tottenham caretaker manager Cristian Stellini and Brighton boss Roberto De Zerbi.
Both men were red-carded in the second half following a melee which had been brewing since the pair exchanged angry words before the game kicked off.
Brighton's hopes of gate-crashing the top-four battle took a big knock and they dropped to seventh with 46 points.
After two costly draws against struggling Southampton and Everton, Tottenham's season appeared to be petering with grumbling from the stands but the reliable duo of Son and Kane at least kept them in the hunt for the top four.
Son's 10th-minute opener was the kind of goal he used to score for fun but has been sadly missing this season.
Cutting in from the left he curled an unstoppable shot into the opposite top corner to become the first Asian player to score a century of goals in the Premier League.
He dedicated the goal to his grandfather who recently died.
"Scoring 100 goals in the Premier League is a massive thing. I was really emotional because I have had tough moments in the last few weeks," he said.
"I hope all the Asian players -- especially in South Korea -- look at this achievement and believe they can do it as well."
While Tottenham's fans celebrated the win, it was another lacklustre display from their side and Brighton will wonder how Dunk's 34th-minute header from a corner was their only reward for a display that was too lively for their hosts at times.
Home defender Eric Dier cleared a Kaoru Mitoma corner off the line early on, Mitoma had an effort ruled out for offside and Spurs keeper Hugo Lloris was forced into saves from Alexis Mac Allister and Moises Caicedo.
Solly March fired wide after Dunk's equaliser and Brighton thought they had taken the lead after the break only for Welbeck's effort to be ruled out by VAR because it had brushed Mac Allister's arm on the way into the net.
Tempers boiled over on the touchline as De Zerbi and Stellini got into a furious argument that briefly stopped play before referee Stuart Attwell dismissed both men who continued their verbal slanging match down the tunnel.
