Not Ranger-related, but baseball-related.  For some reason, I've always wondered what would happen in the following situations.

1. A team that is horrible (i.e. KC Royals) trades their only player named to the All-Star team AFTER the lineups are revealed, but BEFORE the All-Star game.  What would MLB do (in relation to the every team must be represented "rule")?

I know the Tigers came close to doing this in 2002 when they traded Jeff Weaver in this "window", but for some reason, Robert Fick got the Tigers' lone spot while Weaver was probably more deserving.

2. A team that is out of the playoff race decides to trade their biggest trading chip (i.e. Carlos Lee) who is a free agent after the season.  Is it allowed/possible for the Brewers to negotiate a contract extension under the table (giving Carlos Lee a couple extra million for agreeing to play the next 2 months elsewhere), trade him away (netting a nice prospect/player package), and then resign him in the offseason to the "extension" that was agreed to beforehand?

Think anything has ever happened like this?  Would it be possible?
