It all depends on the workload.
If you can really swing it DH.
Easiest position on the field to give you the most amount of rest is 1B, not a lot of work for your arm to play there, but it keeps you active and moving, and helps with your fielding ability.
2B would probably be the next best place to get a rest, gives your arm a nice little workout and you get to move around more then if you were at 1B.
I wouldn't want the be an OF the day after I pitched, but again it depends on the workload.
SS/3B again depends on the workload
Wouldn't want to be behind that plate, that's too much throwing. If you really think about it we get all bent out of shape about pitch couts, what about the Catcher? (I had this talk with a Catcher a few years ago, very interesting to see thier point of view) He doesn't really get a break. Most Coaches want their Catcher to throw that ball back sharp and on a line each and everytime to their Pitchers, then if someone tries to steal....
Just my :twocents:
