08:13 AM ET 09.21 | Expensive teams that fail rarely help the causes of those who have built them. The Marlins are planning to fire president and team architect Larry Beinfest, perhaps as soon as next week, according to two high-ranking executives with knowledge of the move but not permitted to speak publicly because the final decision will be made by owner Jeffrey Loria. Beinfest would be replaced by Dan Jennings, the Marlins assistant general manager and vice president of player personnel. ... [The] two Marlins executives say they would be stunned if Beinfest is the only change. Manager Ozzie Guillen, in the first year of a four-year, $10 million deal, had private differences with Beinfest but is expected to keep his job. For now.
