In strategy set relief to conservative, and closer to regular--maybe try no closer role.
I would set the three 8 inning pitchers to F4, and probably Martinez too to keep them in the game as long as possible. Maybe all the way to F1 if you can get away with it.
Maybe set both Crawford and Campbell as mopup (the better one as 1st mopup), or set the starter/reliever that don't go as often as 1st mopup with your worst pitcher as 2nd mopup, and your best reliever as every thing else.
That is how I kept my cheap pen from pitching much here--had more than half of my games as complete games.
It was a mystery league though
