"I have no interest in going outside the organization, put it that way," Cashman said. "It doesn't mean that we won't do that at some point, but it's not something I want to do. That's certainly not something I'm doing at this stage."
The Yankees are shuffling their bullpen to have David Robertson and, to a lesser extent, Rafael Soriano soak up save opportunities in Rivera's absence.
"I'm hopeful that we have all the answers from within," Cashman said.
Cashman has also said that he does not want to move a starting pitcher like Phil Hughes into the bullpen to address the sixth or seventh innings.
