Hall of Famer Nolan Ryan is departing his role as executive advisor to Houston Astros owner Jim Crane, according to Mark Berman of Fox 26.

"I will not be back with the club and will leave it at that," Ryan said in a text message to Berman.

Reid Ryan - son of the former major-league pitcher - announced earlier Thursday he's been moved from his position as the team's president of business operations to executive advisor in business relations.

"Jim Crane has been a great owner for the city of Houston, and I thank him for the opportunity to lead the Houston Astros organization," Reid Ryan said in a statement.

The elder Ryan had held his position with the Astros since 2014. His son was hired in May 2013.

Additionally, Crane's son Jared has joined the Astros' leadership team to serve in a "broad variety of functions related to the operations of the Astros business" alongside his father, the team announced in a statement obtained by Brian McTaggart of MLB.com.
