Two late goals from Thai Port claimed a vital three points as they defeated BBCU 3-1 at the Rajamangala Stadium.
Jean Marc Beyeme, in the BBCU goal, had to be alert in the first 20 minutes to tip a long swerving shot from Thongchai over the bar, and then a free kick by the newly introduced sub, Alex Ruella, around the post.
It was then Wanlop's turn to be called into action as his foot blocked from Mongkol, and a few minutes afterwards he made an excellent low save after Jacob Aikionbare had neatly set himself up.
Shortly before the break, the goalkeeping baton was passed back to Beyeme as he blocked a Ba-We volley inside the six yard box.
The first goal of the game came on 59 minutes when Thai Port were awarded a penalty after an elaborate flick from Watson sent Sarawut on his way. With the advancing keeper approaching, there was only going to be one outcome as the pair collided at the edge of the box, and the referee duly obliged by pointing to the spot. Watson made no mistakes from the penalty kick to make it 1-0.
Within a couple of minutes the Big Bang levelled as ex Port striker, Jacob Aikionbare, knocked in a parried shot by Wanlop to level matters.
In the 84th minute, Kim Ba-We beat the offside trap to cut back for Ruella to score with a diving header.
The game was wrapped up three minutes later as as free kick from the left was knocked in of the knee off BBCU's Wiratrot to make it 3-1 to the Klong Toei side.
