MODIFY SIM ROSTERS:
Edit Pitching Lineups for simmed games
Edit OFF/DEF lineups (vs RHP) for simmed games
Edit OFF/DEF lineups (vs LHP) for simmed games
This section is similar to the previous option (set 1P lineups) so I won't post all of the screens again. The difference is that here you simply make tweaks to your SIM rosters only.
When done click the 'OK' button, do not click 'COPY' because that will import & paste your 1P rosters (you can edit & import 1P rosters to SIM but you cannot edit SIM rosters and import to 1P.)
