PHOENIX -- The Suns officially announced four new additions to Earl Watson's coaching staff on Wednesday.

Associate head coach Jay Triano, assistant coach Tyrone Corbin, assistant coach/player development coordinator Marlon Garnett and player-development coach Scott Duncan will join two holdovers from the previous staff: assistant coach Nate Bjorkgren and player-development coach Jason Fraser.

"As a family we are excited with the additions we have made into our program," Watson said in a statement released by the team. "Each coach possesses a unique passion to teach, and the chemistry of our staff is as important as the structure of our roster."
