Samu Manoa signed a new three-year deal with the Northampton Saints of the Aviva Premiership Wednesday.
The 26-year-old, who joined from San Francisco Golden Gate in the summer, has featured 23 times in his debut Premiership season.
"I'm very happy to be here," Manoa told BBC Sport. "The club's been great to me and my family so that's why I decided to stay here and sign this contract.
"Every single game I've played in has been a highlight for me."
Coming from the Super League in the States and jumping straight into the pros was big for me at the time.
"I've been learning a lot and at this stage I'm pleased with how I've been playing."
Director of rugby Jim Mallinder told BBC America of the Eagle, "Samu has adjusted to the professional game well and is starting to make his mark in Premiership rugby.
"He is a natural athlete and has all the skills and physical attributes to be a good player.
"But he is just at the start of his professional career and there is more to come as he gets more game time and experience."
Manoa missed the 2011 World Cup to take his shot with the Saints, and with this contract, that sacrifice has paid off.
