Sowden-Taylor made his Welsh debut four years ago against Italy and was a member of the squad which won the RBS 6 Nations Grand Slam that year. Since then he has gone on to win seven caps as Williams has virtually had a stranglehold on the Wales No7 shirt.
"I would just like to get some game time on tour," said Sowden-Taylor who was taking a quick break from Wales training on the new 3G pitch at their Vale of Glamorgan base.
"Hopefully I will get a start and do myself justice. I always try and do my best whenever or wherever I play," he added.
With caretaker coach Robin McBryde selecting some young blood in the back row ranks with Scarlets rookies Rob McCusker and Josh Turnbull being joined by Blues team mate Sam Warburton, Sowden-Taylor is in the rare position of being one of the senior players in his position on tour.
"I haven't seen a lot of Josh but I played against Rob a couple of weeks ago and he was really good at the breakdown. Sam will be like the rest of us, all wanting to put their hand up. This tour is a great opportunity for the boys. With so many senior players away with the Lions it's a great chance to put down a marker for the World Cup squad."
