Ospreys Owen Watkin has become the third player to commit to the region this month.
The 21-year old from Bridgend has signed a new two-year contract that ties him to the Ospreys until at least summer 2020.
One the brightest prospects in Welsh rugby, Watkin has already played 24 times for his home region, scoring three tries, and won his first senior Wales caps in November.
"I'm happy to commit to the Ospreys, I'm enjoying playing here, enjoying my time with the boys, and I'm looking forward to the future and what we can achieve as a team" Watkin said.
"I'm just looking to play for the region as much as I can for as long as I can. It was a great experience for me in the autumn with Wales but it's important I bring that back to the Ospreys and use it to learn and continue developing.
"This is a great place for development, there are a lot of young players who have come through to play for the senior team, boys I played alongside at age-grade, and that shows the system here works. I'm really proud to be a part of it and really excited about the next couple of years."
Watkin came through the regional development pathway via Bryncethin RFC, Ysgol Gyfun Gymraeg Llangynwyd, Bridgend College and the Ospreys age-grade set-up. A WRU U18 title winner in 2015 alongside the likes of Keelan Giles and Will Jones, he was capped by Wales U18 and U20 level, winning a Grand Slam the following year.
He made his senior Ospreys debut in September 2015, catching the eye in an 18-20 Liberty Stadium.
