**It’s day three in our 12 Days of Derbies countdown to the Guinness PRO14 festive schedule.** And we have an absolute barnstormer of a game from Championship yesteryear for our latest entry, with Wales taking centre stage for a Boxing Day derby epic from 2015. Ospreys and Scarlets contested a pulsating encounter in Llanelli, with the visitors eventually prevailing 27-26 after surviving a last-minute scare at Parc y Scarlets. With the two sides due to face off on Boxing Day once again this year - this time at the Liberty Stadium - what better time to remember one of their most entertaining collisions. **Scarlets 26-27 Ospreys, Parc y Scarlets, Llanelli - December 26, 2015** The hosts started the game on the front foot and their early pressure forced an early penalty when Ospreys prop Dmitri Arhip was penalised for coming in at the side. Scarlets opted for a driving lineout rather than the kick at goal but the decision proved costly as former Ospreys No.8 Morgan Allen knocked the ball on with the try line begging. The men in red would not be discouraged, though, and breaks from Steff Evans, Rob Evans and Ken Owens provided the foundation for Hadleigh Parkes to put John Barclay in.
