Derrick Williams announces that he's signing with Miami Heat

MIAMI (AP) Free agent forward Derrick Williams announced Friday that he's agreed to sign with the Miami Heat.

A person with direct knowledge of the negotiations confirmed the one-year deal to The Associated Press. The person spoke to the AP on condition of anonymity Friday because neither side had announced the terms. The signing was first reported by Yahoo Sports.

Williams is entering his sixth NBA season. He's spent time with Minnesota, Sacramento and New York. Williams averaged 9.3 points in 80 games last season for the Knicks, mostly as a reserve.

''Excited for the opportunity to play for the (at)MiamiHEAT,'' Williams wrote on Twitter. ''World class organization.''

The 6-foot-8 Williams also says he's looking forward to playing for Heat coach Erik Spoelstra. Williams was the No. 2 overall pick in the 2011 NBA Draft.
