Reid Ryan, son of the legendary Nolan Ryan and an accomplished businessman in his own right, appears in line to replace George Postolos as Astros president, sources told CBSSports.com.

Ryan was first reported to be a "strong candidate'' for the top Astros job by FOX 26 Sports in Houston, and people familiar with the situation say he is the likely successor to Postolos, who resigned this week after a short term as team president.

Ryan's iconic father previously had been speculated as a long-shot candidate in light of some issues he's had as CEO of the cross-state Rangers, but Nolan Ryan told his friend and Dallas radio host Randy Galloway in answer to whether he might take the Astros president job, "I don't think so. How's that? ... No, I'm sure they'll fill it with the right person.''

Considering that job is now expected to go to his son, Nolan Ryan's answer seems interestingly coy now.

The Astros are not commenting on their vacant president's job.

Reid Ryan, an Astros batboy who has gone on to run the team's Double-A team, will be a popular choice, according to people with team connections. Ryan, 4,1 is CEO of Ryan Sanders Baseball Inc., which includes the Triple-A Round Rock (near Austin, Texas) Express and the Double-A Corpus Christi (Texas) Hooks.

"He's very bright and would be great in that role,'' said a person who's had dealings with the younger Ryan. "He's an out-front personality and good operator.''

Postolos, meanwhile, who announced that he was leaving to go back to his consultancy work, had been "at odds'' in recent months with new Astros owner Jim Crane, sources said. Much of the source of that "friction'' was said to stem from the Astros' TV deal, which is currently in limbo.

Sources suggest Postolos, also a past Rockets president, was actually forced out, though the announcement was couched as only a resignation.
