2012 Roy Oswalt: Relief fastball versus SP fastball

It was pretty obvious that Oswalt struggled as a starter down in Texas last year, earning him a couple different assignments to the bullpen. I went through his pitchf/x data for the season to differentiate Oswalt's effectiveness in the two roles and found some evidence that he could still be a valuable piece coming out of the pen in 2013. In a small sample, Oswalt's fastballs missed bats about twice as often when he was coming out of relief (15.93% versus 8.39%). I believe this is a good sign for Oswalt, because he's relied heavily on his fastballs for success over his career (64.2% frequency, +132.5 runs).
Would Oswalt be worth pursuing? What should the Twins be willing to pay?
