UNDATED (AP) — Dion Waiters is staying with the Miami Heat.

A person with knowledge of the situation says the shooting guard has accepted a four-year, $52 million contract.

Waiters averaged 15.8 points in 46 games for the Heat last season, a shade below his career high set with Cleveland in 2013-14. He was a key figure as Miami went 30-11 in the second half after losing 30 of its first 41 games.

The Heat went 27-19 when he played, 14-22 when he did not.
