Yeah, I don't understand the decision. Even something like the shadows affecting the teams differently doesn't really make sense since that would happen in an open-air park too. And I could understand if this was an evening game, and they were worried that the later it gets, it could get cold for the players, but seems to me that as long as the rules are the same in the post-season as they would be in the regular season (so the team isn't doing something like opening the dome while there's a chance of rain in order to get weird delays), they should simply treat it the same. And can anyone imagine a day like today during the regular season not having the dome open?
