Pichet In-Bang's hat-trick was not enough to prevent Sisaket falling to a thrilling 4-3 defeat at home to Bangkok Glass on Sunday.
The sides' relatively low-scoring starts to the Thai Premier League season did little to suggest the clash would see goals, but a second-half flurry entertained those in attendance at the Sir Nakhon Lamduan Stadium.
Indeed Bangkok Glass led just 1-0 at half-time thanks to Goshi Okubo's opener, while Sisaket were made to play for almost an hour with 10 men when Todsapol Karnplook received his marching orders.
The away side took advantage after the break with Lazarus Kaimbi and Leesaw registering on the goal sheet and, though Pichet notched his first in the 69th-minute, it looked like being a rout when Piyachart Tamaphan made it 4-1.
However, Pichet scored twice more - either side of a red card for Bangkok Glass' Suradet Thongchai - in a late rally to ensure a nervy ending, but it proved to be too little too late for Paniphon Kertyam's men.
