If there is such a thing as a "leverage index" I think you would find that Akin is below any of the big three. Maybe about even with Webb depending on whether the matchups are RHB or LHB. Tate is the only other guy with options but isn't the type of guy to take one for the team in an extended innings situation. If that happened, you option the guy who is going to be out 3-4 games anyway. Baumann, Webb, and Yohan are all out of options.
