If he's comparable to Gamel, he's a guy you can spot start once in a while in CF but you really don't want to be playing him there. Also reports across the board are that he has a bad arm, so putting him in RF is a pretty significant liability. Gamel has done fine when playing center.......Grisham isn't going to replace Cain full time and Yelich is your right fielder......so he will likely see most of his time in left.....but has the ability to move around if needed, It will be ok... ..Yelich doesn't have a strong arm and either does Cain.
