The winter meetings have been quiet for the Pirates, with most of their week dedicated to the Andrew McCutchen talks, which have since ended with the Nationals moving on to Adam Eaton, and the Pirates deciding to keep McCutchen. It seemed that the McCutchen talks were holding things up, as the Pirates couldn't really determine the direction of their off-season until those talks were finalized.
Now that the Pirates are keeping McCutchen, they have a set direction for the off-season, and the biggest goal for them would be to add starting pitching. We might start to hear more rumors on that front, especially with more names entering the trade market this week, and the free agent market opening up at the top after the signing of Rich Hill.
