HOUSTON (AP) — Reid Ryan has been introduced as the new president of the Houston Astros.

Ryan, the eldest son of Hall of Fame pitcher Nolan Ryan, was the CEO of Ryan-Sanders Baseball, which owns the Triple-A Round Rock Express and Double-A Corpus Christi Hooks.

The 41-year-old Reid Ryan helped create the Express, an affiliate of the Texas Rangers and the Hooks, an Astros’ affiliate.

His father played for the Astros from 1980-88 and spent four years beginning in 2004 as a special assistant to the general manager in Houston before joining the front office of the Texas Rangers. His famous dad and former Astros great Craig Biggio were on hand Friday for the announcement.

The younger Ryan takes over the position that was left vacant when George Postolos resigned on Monday.
