It's a minor-league deal. Kensing has pitched in 134 big-league games, most of them with the Marlins. He last appeared in the big leagues in 2009. He does throw hard, but his major-league results have mostly been terrible, so it would probably take a disaster to get him to Pittsburgh. A reliever who can throw gas in the mid-90s (as Kensing did a few years ago in the big leagues; I'm not sure what he throws now) could make a late-career transformation, of course, but realistically, that probably won't happen.
