Pirates GM Neal Huntington isn't content with his bullpen, based on comments made to Chuck Finder of the Pittsburgh Post-Gazette. The locks are Matt Capps, John Grabow, and Tyler Yates. Craig Hansen and Donnie Veal could be lost if they're not kept in the bigs.
Huntington would like to add pitching to the mix, mentioning free agency but qualifying that route as "very unlikely." The Bucs may prefer to acquire an out of options player as they did with Yates last year. Here's my partial list – maybe Angel Guzman or one of the Orioles' pitchers would work (my own speculation). Dejan Kovacevic of the Pittsburgh Post-Gazette adds that the Pirates are also looking for starting pitching.
