Last night at MLBTR, I discussed the remaining offseason needs of each team in the NL Central. What stands out for the Pirates, of course, is the glut of left-handed pitching in their bullpen. They've got Tony Watson at closer, plus Felipe Rivero, Antonio Bastardo, Wade LeBlanc and Tyler Webb.
It isn't at all automatic that Rule 5 pick Webb will contribute in 2017, and it might not be that LeBlanc will either. But even that leaves three lefties, raising the possibility of a deal. They almost certainly won't trade Rivero, who appears to have closer-type upside and has five years of control remaining.
