Every great bullpen is built from within. You build from a core and then fill in when needed. The Yankees had a dominant pen in the late 90s by building around guys like Mendoza and Rivera and adding in guys like Nelson and Stanton. We had a rough run from 01 to a couple years back when we kept dealing live armed kids and signing veterans who fell through the cracks (Steve Karsay anyone?). And we got back to pen prosperity by growing a solid pen. In 09, it was Hughes and Robertson setting up for Mo. In 2010, it was Chamberlain, Robertson and a couple others contributing in front of Mo. This yr, it was Robertson, Soriano, and Chamberlain with Boone Logan stepping up. Logan was a journeyman who was effectively groomed and retrained in the Yankee system and is now a viable lefty setup man. This is how you go about it. If I were the sox, I'd see do this....
Promote Ranaudo to AA, if he dominates, convert him to the pen for the stretch run and see if he can give you a shot in the arm in September. Have Doubront be a lefty swing man. Keep Bard, re-sign Papelbon, keep Aceves in the pen.Keep Morales as well, as he seemed to turn a corner, and see how Weiland and Bowden might fare out of the big league pen. If one of them clicks, so be it, if not, you can deal for a reliever at the deadline. You're just as likely to hit with a kid you groomed out there as you will with an older, defined reliever who will be many times more expensive
