i picked up a guy off waivers who hasn't pitched in over ten days yet is still at 0 (has been for over a month). why would that be? 32 for stamina. why isn't he recovering?

Check his game log pitching history.  Most likely he pitched a number of consecutive days at 0%.  Though it doesn't show, his fatigue is well below 0.  He's recovering points based on his durability, but if he's deep in the negative numbers, it may take a while for him to start showing signs of recovering.  Once he gets above 0, you'll notice his recovery.

perfect.  that's what i figured.  thanks.
