Pro12: Scarlets v Munster (Sat) Pro12: Scarlets v Munster Venue: Parc Y Scarlets Date: Saturday, 16th February Kick-off: 18:30 (GMT) Coverage: Live on S4C. BBC Radio Wales and Sport Online for score updates Welsh squad members Josh Turnbull and Liam Williams are both included in the Scarlets' line-up for their crunch Pro 12 match with Munster on Saturday. No8 Turnbull captains the side after being released by Wales for a match coach Simon Easterby says could boost the Welsh region's play-off ambitions. Scarlets (fifth) are a point ahead of Munster in the race for the top four. "It is a chance to open a bit of a gap against a team in a similar position to us," said Easterby. Munster are a position below us there's very little in the top four positions in the league so if we can get that result we can start to cement that position in the top four. The top four teams play off for the Pro 12 title at the end of the season. And former Ireland international Easterby knows the visitors will be tough opponents. "Munster come to town off the back of a really good result against Edinburgh at home," he said. They pose a really big threat to us, but we should be really confident. Munster include Irish squad members Ronan O'Gara and Donncha O'Callaghan in their line-up, so Ian Keatley reverts to full-back from fly-half. Mike Sherry will captain the Munster side, with the 24-year-old becoming one of the youngest players to lead the side. Sherry, who agreed a new two-year contract last month, starts in Parc Y Scarlets ahead of Damien Varley, who also has just penned a deal that keeps him in Munster for the next two seasons.
