A late try saw Tumble edge out Pontyberem 26-21 in a tight local derby at Pontyberem Park.
It was the home side who started strongly, with two tries from captain Adrian Williams giving them a 15-7 lead at half-time.
However three second half tries were enough for the visitors to bank a bonus-point win in muddy conditions in front of a large vocal crowd.
Pontyberem did get a losing bonus point, their next match is at home against St Clears RFC.
