Nonetheless, it took them 35 minutes before they opened the scoring through Yves Ekwalla Herman, who curled an effort from inside the area into the far corner after the Ratchaburi defence had failed to clear their lines.

Ratchaburi pulled one back two minutes later when Adisak Kraison scored an own-goal, but the night belonged to the Thunder Castle, who capped off the victory in the 88th minute when Jerkovic grabbed his second of the game, leaping highest inside the area to send a looping header into the top corner.
