Ospreys: New deal for wing prospect Giles
The 18-year-old Giles has impressed with Wales Under-20 during their Grand Slam success earlier this year.
Stepping up two years to play for Wales U20 at the beginning of 2016, he started in all five matches as the Welsh youngsters completed the Grand Slam, scoring three tries.
He is the third member of the Wales U20 Grand Slam squad to have signed professional contracts with the Ospreys.
"I've come through the pathway here, it's my home region, and I'm obviously delighted to have signed this contract," Giles said.
"It's been a pretty surreal year for me if I'm honest.
"I've achieved more than I could have hoped for and the Grand Slam was something I'm particularly proud of. It was a good year all round, ending up with an unexpected call to go to New Zealand with the senior team, which was pretty incredible, and something I really enjoyed."
Ospreys head coach Steve Tandy said Keelan is a young man who potentially has a very bright future ahead of him.
"His development over the last year or so has been impressive and is a sign of his character and attitude," Tandy said.
"He's a level headed and diligent individual who is prepared to work hard and put the effort in on and off the field.
"He's in an environment that will look after him and give him the tools and support he needs to be the best he can be, and if he keeps working hard then there is no reason he can't flourish as a player and a person."
