Or you could lower your other 4 Sp's pitch counts, go with a 4 man rotation and make this guy a LRA.
Or he'd make a good Tandem B after a LHSP Tandem A. In fact, if you lower his pitch count to 40 you could probably tandem B him every third day. It would require a lot of manual switching around of your pitchers but if you're on the site anyway ...
