I think since they can choose the pitcher, we should be able to see if we are facing a lefty or a righty. I think it would be fair because it would really help set up a line up. I don't even care if I know who it is, but knowing if what side they thrown on would help.
Why should it be implemented? This is what happens in real baseball, you actually know who is throwing and get to set up the lineup however you want since you know who is throwing.. just a suggestion.
