Wing Tom Grabham has signed a new two-year contract with Ospreys.
The 23-year-old Wales Sevens cap will now remain at Liberty Stadium until at least summer 2017.
"I'm really pleased to sign for another two years," Grabham said.
"The main goal for me over the next two years is just to pull on the jersey as much as I can... it's an exciting time for the Ospreys, we are a young team but we're ambitious about what we can achieve over the next few seasons."
Gragham graduating as a scrum-half from Tondu RFC to the senior squad at Ospreys via Bridgend District, the Eyasses and Bridgend Ravens.
His senior debut came in an LV= Cup defeat to Exeter Chiefs in October 2011 and he has now featured 34 times for the Ospreys, scoring five tries, with 15 of his appearances coming this season.
Andrew Millward, Ospreys rugby general manager, said: "The coaches made the step, a few years ago now, of switching him from nine to the wing, and he showed some real initial promise.
"Some of the intricacies of the position needed refinement, but to Tom's credit he is a really good learner, is very diligent in everything he does, and he's gone away to look at all aspects of his game in order to understand the position fully, technically and tactically.
"He's now got a greater understanding of what is required from a winger at this level. He is learning how to make the kind of snap decisions that can change the outcome of games, and recently we've seen him become a big part of our attacking game."
