Here's the new build of the Pirates' 25-man roster, updated to include the Joel Hanrahan deal and the Francisco Liriano signing. Obviously, the roster coming out of Spring Training will look somewhat different.
The key here is that there's no longer space for Jose Tabata on the 25-man roster. He's out of options, but I just don't see where he fits. The Bucs could, of course, carry a six-man 'pen or only one utility infielder, but they rarely do such things. If the Pirates were to trade someone from their stash of corner players (Tabata, Gaby Sanchez, Sands, etc.) for a reliever, that would make a bunch of sense. (I'm still happy to have Travis Snider, whose upside I still like more than any of those three players, but the Pirates' current roster needs make the Brad Lincoln-for-Snider deal look a little funny.) In any case, I'd expect the Pirates to hunt for one more reliever.
