A source believes that the Phillies are more interested in Pedro Martinez than they are letting on. Philadelphia general manager Ruben Amaro Jr. told ESPN that the club was "just exploring all possibilities" when they watched Martinez throw a simulated game in the Dominican Republic on Tuesday. The source says he is also led to believe that the Phillies have let Martinez know what they were willing to pay him for the rest of this season. The amount was likely to be less than the prorated $5 million contract, plus incentives, that he has been seeking.
