Sources: Kyle Singler agrees to $25 million extension with Thunder

Kyle Singler has agreed to a five-year extension worth nearly $25 million with the Oklahoma City Thunder, league sources told Yahoo Sports.

Singler, 27, rapidly grew into an important part of the Thunder’s bench upon arrival from Detroit in a three-team trade. He has averaged 8.1 points and 3.4 rebounds in three seasons in the NBA.

Singler was a restricted free agent. He can't officially sign the contract until July 9 when the league's free-agent moratorium ends.
