Free agent center Willie Reed has reached agreement with the Brooklyn Nets on a one-year contract, league sources told RealGM.

Reed, who has starred on the Miami Heat’s summer league entry in Orlando, will sign a mostly guaranteed deal, sources said.

When reached to confirm, Reed’s agent, Joel Bell, declined comment.

In four summer league games for the Heat, Reed has averaged 13.5 points, 7.8 rebounds, nearly two blocks and 60 percent field-goal shooting. He has emerged as a legitimate NBA rotation prospect, a frontcourt player agile enough to finish inside and recover on defense.

Out of Saint Louis in 2011, Reed has signed NBA contracts with the Sacramento Kings, Memphis Grizzlies and Nets over the past three years. The 6-foot-10 big man went to training camp with the Nets last October.

Reed split last season with Iowa and Grand Rapids in the NBA D-League, averaging 16.4 points, 12.1 rebounds and 1.9 blocks per game.
