Buriram United took over the second spot in Thai League 1 on Sunday night, beating True Bangkok United, the team harbouring a burning desire to wrest the Thunder Castle's title, 1-0 in an away game.
The match seemed heading for a goalless draw before Pedro Junior struck five minutes from full-time to grab three points, leaving the defending champions just a point adrift of leaders PT Prachuap.
Bangkok United's first loss of the season sent the capital side skidding down to sixth place in the table.
Port missed their chance to take over the top spot following a 1-1 home draw against PTT Rayong last night.
Port gained the upper hand when Spanish midfielder Sergio Suarez moved up from right and delivered the ball to defender Kevin Deeromram in the middle of the box. Kevin's shot was deflected into the goal by Victor Igbonefo in the 20th minute.
Rayong fought their way back into the match 14 minutes later when Jay Emmanuel-Thomas set up Apiwat Pengprakon to smash the ball into the roof of the net and cancel out Kevin's goal.
Rayong were peppered with attacks late in the match but kept their composure and weathered the storm.
Port, on the other hand, were left frustrated by their inability to find the winner and collected a couple of unnecessary yellow-card warnings in the five-minute injury time.
Also on Sunday night, Samut Prakarn City moved into fifth place following a 0-0 stalemate at home to Sukhothai.
In Saturday night's late game, hosts Nakhon Ratchsima failed to break Trat's resistance throughout and the battle ended in a goalless draw.
