Off-loading in tackles and support play was of the highest order by the home side and when called upon to defend they were also adept at ensuring that their try line would not be breached.
From the off they were direct in their approach with two breaks of tackle bringing them into the danger zone before second row Caitlyn Smith picked up and charged over. The effort was improved with Lauren Smyth’s conversion.
A little later a quickly taken short penalty led to Hannah Jones adding another five pointer, followed by an incisive break by competent scrum half Kayleigh Powell who managed to complete the grounding despite an excellent cover tackle by fullback Sara Roberts. Smyth was again successful with the conversion to establish a 19-point cushion with 12 minutes played.
RGC, to their credit fought back and opted to run a few penalties when the kicking option would have undoubtedly put points on the board. Centre Sophie Ellis showed an excellent appetite for the game with an exceptionally high tackle count and the ability to cross the gain line but despite her efforts the Ospreys defence stood firm.
Molly Kelly also carried well and stand-off Sioned Phillips put in a stern shift with numerous important clearance kicks. However with the Ospreys breaking out of defence at pace and in numbers another three tries followed before half time, full-back Sophie Davies, Smyth and No8 Gwen Crabb all touching down.
The opening raids of the second half saw more of the same with the Ospreys using their full list of replacements who were equally as effective.
Stand-off Megan Whittaker her five pointer after four minutes. RGC for the next 10 minutes held their own with Hannah Hughes having one fine touch-line run and Ellis breaking numerous first up tackles but not having sufficient support at hand.
As the game progressed more space became available and the Ospreys capitalized with centre Ffion Jones rounding off one move and fullback Sophie Davies adding her second of the day soon after. The latter was converted by replacement Jasmine Hare to draw the match to a conclusion.
