Judgement Day double-header from the Principality Stadium in Cardiff.
Ospreys 19-36 Cardiff: Keiran Williams try puts Ospreys ahead, before Alex Mann and Gabriel Hamer-Webb doubles give Cardiff handy half-time lead. Ospreys' Will Spencer and Kieran Hardy narrow gap, but late penalty try and Hamer-Webb's hat-trick seal Cardiff win.
Dragons 23-31 Scarlets: Henry Thomas try opens scoring for Scarlets, with Jared Rosser replying for Dragons. Ashton Hewitt and fellow Dragons wing Rosser cross in quick succession after the break, but Alec Hepburn, Vaea Fifita and Blair Murray claim tries for Scarlets.
Cardiff lift the Welsh Shield as top dog in games between the four Welsh regions during the United Rugby Championship season.

To be fair, if you score a hat-trick in a Welsh derby, then you probably deserve the award.

Mark Jones will be very frustrated by that performance.
Ospreys had 60% possession, 60% territory and played for half an hour against 14 men - yet they've ended up heavily on the wrong side of the scoreboard.
The crowd in the middle tier of the stadium are doing their best to get a Mexican Wave going... at the moment it's not making it past the 22-metre line.
