"I'm going to wear whatever they give me," Beckett said when asked about his boyhood idol and fellow Texan. "It would definitely mean something to me." Beckett, in a conference call Saturday from his offseason ranch, said he's "pumped" to be playing for a passionate fan base after coming from the Florida Marlins.
