After briefly contemplating filing tampering charges against the Boston Red Sox for acting improperly in discussions with the agent for J.D. Drew, baseball sources say the Dodgers have decided against taking any action. Drew opted out of the last three years of his contract Nov. 10, walking away from $33 million and raising suspicion that agent Scott Boras had discussed Drew with another team while the outfielder was still a Dodger. Drew signed a five-year, $70-million deal with the Red Sox last week. The Red Sox and Boras denied any impropriety, which would have been difficult to prove.
