Every off-season, sign as many minor league free agent SP's with 20-30 durability and 80-100 stamina as you can. Offer them all contracts (because many will sign with other teams). Even if their L/R splits are 10/10 they can play in LoA and Rookie ball at least. After the season has already started, if you are really desperate, and there are no minor league free agent SP's available in your league, then check the tryout camp (Go to GM tab ->Contracts->Tryout camp report). They are garbage but they are at least bodies.
Also, LoA through AAA has active/inactive designations. You can stash a bunch of players at each level as inactive (10 per level I think). So if your staff is gassed, inactivate the 0% guys and activate the guys that are sitting at 100% as inactive. Though if you have enough of the 30STA/90DUR guys I mentioned above sprinkled throughout your minors, you don't even need to use inactive players.
