I mentioned this on the last ESPN 1040 blog update when I reported that the Rays are apparently interested in Rich Harden. There is no need for him as a starting pitcher as the club already has enough depth there, but there are plenty of job openings in the bullpen. Harden is known as a three true-outcome pitcher: he either strikes batters out, walks them, or walks off the mound injured. Since his durability is a problem and his endurance has never been great because of high pitch counts (see Kazmir 2008-2009), it would seem a natural fit for Harden to transition into a relief role.
The table below shows his splits in his career by pitch count range.
Now, compare that to the splits for the departing and popular closer Rafael Soriano:
Color me extremely interested as long as Harden is willing to listen to the role and willing to take a one-year deal heavily based on incentives.
