No, you can't. Because if you don't win the WC game, there is no ALDS. Say Erv doesn't have it and needs to be pulled in the second or even the first. If you don't have someone else rested and ready to step in, your season is over. Given that Gibson is slated to start Friday and Berrios Saturday, it seems like the emergency back up for the WC is Mejia. This is why pushing Gibson back to Friday might not be such a wonderful idea. He was originally slated to start Wednesday. Meaning, he would have been on full rest for the WC. Sure, as it stands now, Gibson or Berrios would be rested for game one of the ALDS. But what if you need one of them (or both) in the wild card game just to get there?
