Yeah, the way I see it and the way Rocco addressed the issue this winter in Rochester (Twins Caravan) is that he (Rocco) wants a seven-man bullpen plus a long man. The long man is technically part of the bullpen, but it seems this role is for a guy who can pitch multiple innings (at least three) and then not be used for a considerable time. The other guys are able to be used every other day with some usage on back-to-back days. The long man would be used in the lowest of leverage situations. To go in that role, the long man has to be stretched out enough to go at least three innings and probably not be high enough on the prospect list that the front office will fret that their development and service time are mostly accruing while watching games. Another key element for the long man is the ability to trade places with somebody in St. Paul. The presence of an option makes a huge difference.
So, with that theory in my head, I'm viewing transactions accordingly. They couldn't bring up an long man candidate to replace Headrick after his major league debut because of 40-man constraints and option rules, but when Maeda went down early, they needed to cover and brought up SWR as the long man while keeping Headrick on the major league team. Headrick isn't going to displace a "real" reliever nor is Woods Richardson long term. If the Twins want to demote Moran and replace him, they'll want another reliever and I don't know who that is. This is all my opinion of course--"I could be wrong now, but I don't think so".
