The Ospreys Daniel Baker fends off the Dragons defence.
Eli Walker and Bowdy Davies guided the Ospreys Under 18s to a second successive victory in the WRU Age Grade Championship, against the Dragons at Newbridge.
Walker, who has been in outstanding form so far this season, produced another faultless performance, whilst Davies capped an excellent display with his first try of the season in a 28-16 victory at the Welfare Ground.
Walker was also on the try mark, with his his second of the campaign, whilst Luke Morgan bagged the third and Owain Williams kicked two conversions and as many penalties on top of a second half drop goal.
Trailing 20-9 to the interval, the Dragons struck back in the second half with a converted try from Matt O'Brien. However, it was not enough to deny the Ospreys a victory that keeps them on the coat-tails of early leaders the Blues.
In the Under 16 Championship it was business as usual for the Scarlets who made it three wins in as many games, against Blues North at Parc y Scarlets.
Having brushed aside Gogledd Cymru and Blues South in their opening games, the Scarlets were 28-14 winners courtesy of another 18 points from outside half Jordan Williams.
Williams, who went into the game with 36 points to his name, from two games, crossed for a try and kicked 13 points via three penalties and two conversions. Daniel Thomas was also on the mark with two second-half tries as the Scarlets maintained their 100 per cent record.
The North must have fancied their chances before the interval when Jack Bennett (try) and Callum Phillips (conversion) kept them in touch. Phillips added a second half try, which he converted, to once again leave the Scarlets looking over their shoulders. However, as team manager Wyn Thomas said; "They gave us the run-around in the first half, but in the end I think we were good value for the win.
"There is no doubt that they are a good side, but we are pleased with the manner in which we played and I felt that Jordan Williams was again the difference."
Blues South, who were 33-15 winners against Gogledd Cymru on Sunday, edged out the Dragons at Taffs Well thanks to tries from Lloyd Chalke and Tom Perry.
Gareth Thompson kicked 14 points in his side's 24-20 victory whilst for the visitors, Luke Morgan and Scott Matthews scored tries and Ethan Davies kicked two conversions. Niall Martin was also on the mark for the Dragons with two penalties, but his contribution came too late to save the game.
