ARLINGTON (AP) – The Texas Rangers have hired Josh Hamilton’s father-in-law as a staff special assistant.

Rangers general manager Jon Daniels says Michael Dean Chadwick will fill a support role for the slugger that was left vacant when Johnny Narron left in November to become Milwaukee’s hitting coach.

Narron joined the Rangers when Hamilton was acquired four years ago in a trade from Cincinnati. His primary role was to support Hamilton, the former No. 1 overall draft pick who rebounded from substance abuse problems to become the 2010 AL MVP and a four-time All-Star.

Last season, Narron added the title of major league assistant hitting coach. The Rangers don’t plan to hire anyone to fill that role.

Chadwick will be like an accountability partner for Hamilton and travel with the team.
