An own goal conceded by Chiang Rai United last night could serve as a double boost for SCG Muang Thong United, who were stripped of their Thai League 1 title by arch foes Buriram United on Wednesday.
The 1-0 win was enough to brighten the Kirins' chances of claiming second spot and earning a right to participate in next year's AFC Champions League play-offs.
Bangkok United were thrashed 3-1 at home by Buriram and fell three points behind Muang Thong, who have a game in hand.
The victory also gave Muang Thong a mental edge over Chiang Rai, who they face in the League Cup title showdown on Nov 22.
After some scattered attempts to score, Muang Thong were given a new lease of life when Chiang Rai defender Artit Daosawang guided Heberty Fernandes' free kick into his own goal in the 61st minute.
The Kirins owe a lot to goalkeeper Kawin Thamsatchanan, who spectacularly warded off a last-gasp spot kick from Felipe Azevedo.
Muang Thong can seal second spot on Wednesday when they play relegated Thai Honda. Chiang Rai meet Police Tero, who were thrashed 5-1 by Chonburi last night, on the same day.
Buriram kept the chase of their own record for most points in a season alive last night when Diogo Luis Santo, Phansa Hemviboon and Jakson Coelho scored for them. Bangkok United's lone goal was delivered by Mario Gjurovski.
Meanwhile, in a big upset, Nakhon Ratchasima edged Bangkok Glass 2-1.
