NEW YORK (AP) — Adam Silver has become the NBA’s fifth commissioner.

The NBA posted a picture on its Twitter account Saturday of Silver holding a basketball and shaking hands with outgoing commissioner David Stern.

“It’s official: Adam Silver succeeds David Stern as NBA Commissioner” the caption read.

Stern retired after exactly 30 years in charge.

Silver joined the NBA as his assistant in 1992 and has been the deputy commissioner since 2006.
