All according to the team's twitter feed.

Since Hawpe reached the end of his time in Colorado, Pirate fans have sometimes speculated about whether the team should pick him up. Now it has. Of course, he hasn't hit much at all since he left Coors and even his good years were almost entirely Coors illusions.

Taillon will probably be with the team only briefly, maybe for a couple innings in spring training games, but those innings will be highly scrutinized. Cole could stick around longer, but I tend to doubt it because he's not going to open in the majors and so the innings will likely go to other guys.
