Defending champions Buriram United moved three spots up to third in the Thai Premier League after recording a hard-fought 1-0 win over Chiangrai United on Friday evening.
Theerathon Bunmathan broke the deadlock for the Thunder Castle at the United Stadium on the stroke of halftime, when he lined up a freekick on the edge of the box and sent a trademark effort into the back of the net.
The incident also saw the hosts reduced to ten men after Fernando Abreu was sent off for a second bookable offence, but Buriram were just unable to make the most of their numerical advantage in the second half.
Nonetheless, they ultimately did enough to claim maximum points and make it two wins in a row, as well as maintain their unbeaten start to the season.
The result also means Buriram are now just a point behind Army United and Bangkok Glass, although both teams now have a game in hand.
Chiangrai United: Intharat Apinyakool, Kiatprawut Saiwaeo, Fernando Abreu, Kazuki Murakami, Krissadee Prakobkong, Yuttajak Kornchan, Phichitphong Choeichiu, Renatinho, Renan Marques, Rungrath Poomchanteuk, Choklap Nilsang.
Buriram United: Sivaruck Tedsungnoen, Chitipat Tanklang, Andres Tunez, Korawit Namwiset, Anawin Jujeen, Prakit Deeprom, Suchao Nutnum, Go Seul-ki, Theerathon Bunmathan, Gilberto Macena, Diogo.
