Setting the Lineup for Every Game

Play One Day will sim all the games for that day. But you don't need to sim each individual game to have control over the lineups. Turn on Commissioner Mode (in the upper left corner of the "Options" dialog in the Tools Menu). This gives you control of every team, and the computer manager won't alter the lineups you set for each team (unless someone is unable to play due to injury).

If you want to set the lineup for each team at the very beginning of the game, with access to head-to-head stats against the opposing pitcher, follow these steps:

1. Turn on Commissioner Mode.
2. Go to the Calendar Page and right-click on any three games. This will trigger a popup asking you if you want to select all games for Play-By-Play Mode.
3. Click More Options' and then click Yes. This selects all games for every team.

This will cause all of the day's games to be opened in Play-By-Play Mode, with the ability to choose the starting pitcher and starting lineup for both teams at the beginning of each game. If you want to sim the game after you've specified the exact lineup, click Finish in the upper right.
