PITTSBURGH -- Before Dan Haren signed with the Los Angeles Dodgers, rumors still persisted that the team was intent on landing Masahiro Tanaka. He knew that Chad Billingsley was on the comeback trail. There was a pretty good chance he'd be looking over his shoulder at some point in the season if he wasn't performing well.Funny thing is, even though Tanaka landed with the New York Yankees and Billingsley's comeback ended with yet another elbow surgery, Haren finds himself wondering whether he has a role in the Dodgers' rotation after all.
