Why would a minor leaguer....

....have ZERO appearances after a sim ?
One of my most promising young pitchers (Sabathia) appeared in NO GAMES after the first sim.....
He had no previous injury, and he was not on my major league roster.....

Now that you mention it, I saw this too.

I went to the Banana League, which just started the 2003 season, and looked the the pitching rosters for all teams. On about 5 of them were minor league pitchers who did not get any minor league playing time.
