snowballs23, also, find the thread on this Forum called "Identifying AAA players, only the charts." You want to know who the AAA players are. They are your real bench players and sometimes one or more might be good enough to platoon or make a regular. You can use them, and drop some of your lesser players in the Waiver Wire, using the cash obtained to get a good reliever, pinch hitter or additional player you need.
In the future, draft a pitching staff and 8 regular position players, and maybe a fourth OF or pinch hitter. Then fill the roster with $200,000 or so players whom you dump in the WW when you get your AAA players when the league starts.
The AAA pitchers are not that great, mostly just mop up or good for a waste spot start to rest your staff. The position players are of real worth though. So don't fall for an old dirty trick of veterans here of offering you a trade of an AAA pitcher for one of your position player AAAs. That is always a bad trade.
Good luck. I will try to bump the classic "Identifying AAA" thread so you can learn how to find out which real historical players they are so you can use them as to the best of your team's needs.
And welcome. There is a learning curve, but read the forums a lot, including old posts and especially the pinned stuff at the top that contrarian23 has posted "The best of Forum" I think it is called.
