Plesac had a good run, but he's damn near 40 and a little trepidatious about the whole life after baseball thing. Jones is back from Tommy John, unsure why his surgeon used a tendon from his toe instead of his forearm. Dominguez, brand new to the show, is that special, dangerous combination: naive and combustible. And Castillo, well, Castillo has to do what bullpen coaches do: hold it all together. Welcome to another year in the bullpen: the thrill of barely being in the majors, the agony of mediocrity.
