Going into the business end of the season, Ponty occupy top spot in the table with an 11 point lead but they know every result will now count in pushing for a retention of the league crown.
The Quins have turned around their season with an excellent run which has produced eight wins from their last nine games – the last of these victories coming at home against neighbours Llanelli last weekend.
The home side make a raft of changes from the team that started a close fought home win over Aberavon last time out. There are new partnerships at centre, where Gavin Dacey links up with Gary Williams, and at half back, where Dai Flanagan plays outside Gareth James.
Club skipper Chris Dicomidis drops to the bench for a well-earned rest with Dafydd Davies given a start in the second row. Veteran flanker Wayne O’Connor taking over the captaincy.
