Dragons flanker Aaron Wainwright, who has helped the Welsh region into second place in Pool 1 of the European Rugby Challenge Cup this season, will make his first start for Wales against Tonga at Cardiff’s Principality Stadium on Saturday. The 21-year-old made his Test debut as a replacement on the summer tour to Argentina and is now promoted to the starting back row as one of 14 changes to the Wales team who pipped Australia 9-6 in Cardiff last Saturday. Wainwright is one of four Dragons in the starting XV, the others being centre Tyler Morgan, hooker Elliot Dee and prop Leon Brown. Two other Dragons – lock Cory Hill and No.8 Ross Moriarty – are on the bench. https://twitter.com/dragonsrugby/status/1063042116484558849 Ospreys lock Adam Beard is the only Wales player to retain his place in the XV. He is joined by clubmate Owen Watkin, who returns to the Test scene for the first time this autumn in the centre alongside Morgan. Inside them is Northampton Saints fly-half Dan Biggar, who came on as a late replacement to kick the winning second-half penalty against Australia last weekend.
