Brent Cockbain hailed a fantastic year for Welsh rugby after the Ospreys added the Celtic League title to Wales' Grand Slam success in the Six Nations.
"It's fantastic for Welsh rugby, the Ospreys doing this one week after the Grand Slam is an absolutely phenomenal achievement," said the Wales lock.
"I'm stoked to be a part of this, we've got a new barn (training facility) and we've got a new stadium at Morfa.
"We're strengthening our squad even more, so rugby is really on the up."
Australian-born Cockbain, whose performances in the Six Nations have forced him into contention for the Lions tour, paid tribute to club and country team-mate Gavin Henson.
The centre struck five penalties, two conversions and grabbed a try as the Ospreys beat Edinburgh 29-12 on Saturday to wrap up the league with two weeks remaining.
"Gavin Henson was on target as usual and kicked them from everywhere," Cockbain, 29, added.
"It was an enjoyable game to play in. Edinburgh came down with a very strong side, they had a lot of Test players and we knew we were always going to have a battle on our hands.
"They played some awesome rugby but we just didn't let them get over the game line at times."
The magnificent end to the season gave some welcome cheer to Cockbain, brother of former Wallaby Matt, whose 13-month-old son, Toby, died of a brain tumour last September.
