Ten man Llantwit Major's unbeaten run in the Cymru South ended with a 1-0 defeat at home to Baglan Dragons.
Ben Stait had led Major to a six-game streak, which earned him a Manager of the Month award nomination as well as player award nods for Matty Kimmins and Ioan Emmanuel.
But the hosts at Windmill Lane came unstuck when Lithuanian midfielder Artiom Legavec put the visitors in front on 26 minutes with his third goal in four games.
Llantwit played out the closing stages a man short after Sean Kelly was shown a second yellow card on 77 minutes.
Major drop to sixth in the table with just four games to go - starting with a Friday night visit to Cambrian United on 21st March.
