Currently the Pittsburgh Pirates and Colorado Rockies rosters are not appearing for the game on 4/25. The roster list states it was refreshed at 11:04 am EDT.
Sorry for the MLB issue today, not sure what went wrong, but the lineups that were unconfirmed were being removed completely. It is all fixed now, just as a side note, we really don't recommend making lineups until the batting orders are confirmed, although we know at times this is not possible.
