Without disclosing where he or she got the information, the unnamed source said that it was about 75 percent certain that Joba will start the season as a starter or reliever.
Depending on what Girardi and the Yankees brass want to do, Joba will come out of the bullpen. Or he won't. Or maybe sometimes he would, like in the playoffs.
What's 100 percent definite at this point is the difficulty to accurately predict what will happen for certain.
Nevertheless, the rumors are true: Joba Chamberlain will pitch for the Yankees.
