The Miami Heat have landed their top free-agent target, getting a commitment Friday night that Ray Allen will leave the Boston Celtics and join the current NBA champions, agent Jim Tanner told ESPN.com.

Heat owner Micky Arison broke the news via his Twitter account by writing “welcome to the family #20.”

It is believed Allen accepted the Heat’s mid-level exception that starts at $3.09 million, which means he left an offer worth twice as much per year on the table from the Celtics.

Allen met with the Heat Thursday afternoon and evening in Miami.
