Injuries, vacations, etc. happen. That's the bottom line.
Without the benefit of full-time employment by MLB, these MiLB guys just do whatever the heck they have to, in order to try and get to the aforementioned level.
The whole '99 situation certainly screwed some of these guys over, no doubt about it. I can only suppose several spots would've opened up from guys that were let go (and not subsequently re-hired) from that nasty situation.
