Camp is fast approaching, and without any moves, this is how the pitching battles will shape up in February and March:
Locke and Cumpton both have options remaining, which works against them. Wandy has to show that he's recovered from his arthritis, and Volquez that he can contribute, even if he is slotted into the fifth spot. If one of those two fail to make the opening day roster, look for Locke to slide in, so the Bucs have another lefty in the rotation. Jameson Taillon may get his opportunity to crack the lineup sometime this summer. The FO may also bring in a back-ender to add some depth, perhaps a guy like Chris Capuano. (We consider AJ out of the mix; but if he returns, he could calm the mid-rotation questions)
Gomez and Pimentel are out of options, while the Bucs haven't shown any indication that they are planning to stretch out Wilson, a minor league starter, to compete for a starting role.
Grilli, Melancon, Watson and the three swing men are pretty well set for the pen. Mazzaro and Morris are out of options in the battle for the last spot. Hughes has two options remaining, while Schlereth, a non-roster invitee, brings a decent MLB record as a LOOGY, something Clint Hurdle has never had in Pittsburgh, and so could join the mix. The Bucs also got back Duke Welker from the Twins. This is a deep position, and if the Pirates swing a deal for a first baseman in the next few weeks, a bullpen arm will likely be part of the package.
