Suphanat Mueanta and Guilherme Bissoli were on target as defending champions Buriram United rallied to win 2-1 at PT Prachuap in the Thai League 1 on Wednesday night.
Keron Ornchaiyaphum gave Prachuap the lead after 23 minutes before Suphanat pulled level for the Thunder Castle in the 53rd minute.
The match referee awarded Buriram a penalty in the 68 minute after Amirali Chegini fouled Martin Boakye in the penalty area, and Brazilian striker Bissoli did not miss from the spot.
Prachuap striker Phantamitr Praphan scored in the eighth minute of stoppage time but the goal was ruled out for offside after a VAR check.
"The three points from today's match are really important, because before this game, no one could beat Prachuap at their home ground for a long time," said Buriram coach Osmar Loss Vieira.
"It was a high-quality game, and these three points are important for us as we try to become champions again."
Prachuap coach Sasom Pobprasert, who saw his team's unbeaten run at home come to an end after 18 games, said, "I don't really think about the team's unbeaten run. The team can play at home and start winning again. I'd rather my team focus on trying to stay up. We need to reach at least 32 points to be safe.
"I would also like to congratulate Buriram for their victory today," he added.
The Thunder Castle have 51 points from 20 games, extending their lead over second-placed Bangkok United to 11 points but the Angels have a game in hand.
Buriram will host Port at Chang Arena on Sunday while Prachuap will visit Khon Kaen United.
