Using Dihigio as a 2b starter but also as utility vs LHP, so he's not starting at 2b too often. His back ups vs lefties are Eddie Collins and Frisch...

However whenever he is not in the 2b position vs lefties somehow he is substituted by Gehringer. I'd really like to stop Gehringer from starting vs lefties and would much rather Collins or Frisch but have no idea what to do. Suggestions requested.
