Coming into the season, the Mariners put together a bullpen composed in large part of hard-throwing righties with inconsistent or below-average command. The idea was that relievers are volatile commodities, and you never know when a guy with good stuff will go all Matt Thornton and suddenly start throwing strikes. With that in mind, here's a look at how the four guys who fit the profile have done so far:

David Aardsma hasn't picked it up. Mark Lowe hasn't picked it up. Miguel Batista hasn't picked it up. And while Brandon Morrow was good a year ago, so far injuries and time off have taken a toll on his command, to the point where we can't yet trust him to locate his pitches when he needs to.

Of the four guys with good fastballs and iffy command, we haven't yet seen anyone figure it out. We still might, of course - it's only early May - but to date the bullpen has been every bit as uncomfortable to watch as many expected, with its 5.3 BB/9 standing as the third-worst in baseball.

Shawn Kelley, by the way, was throwing strikes at a 68.2% clip before getting hurt. With the big league bullpen always teetering on the brink of disaster and Josh Fields pitching like a crazy person in AA, we're going to miss Kelley something terrible while he's gone.
