For your viewing confusion, here are a bunch of Spring Training photos that will look weird to you.
Obviously, Melancon already pitched for another team after the Pirates traded him to the Nationals last season, but this photo still looks odd.
The Locke and Niese pictures are weirdly comforting, because they suggest both those pitchers will be far, far away -- playing for the Marlins is about as close as you can get to being banished while still playing in the majors, and the Yankees (if Niese ever actually played for them) are in a different league and have a set of priorities totally distinct from those of the Pirates.
Not that Pirates fans had an especially long time to develop an attachment to Neftali Feliz, but it's still a shame to see a good player go to a division rival.
And ... well, I'd have more, but no pictures of Matt Joyce in an A's uniform appear to have hit Twitter, and not that many key Pirates changed teams this past winter. There also aren't any pictures on Twitter of Pedro Alvarez sitting at home. That's at least as weird as any of these.
