I don't mind having "set" roles for relievers, but there needs to be some room for adjustment, hence my use of quotes. It is much easier for relievers to prepare themselves mentally when they know the general situations in which they'll enter the game. The setup guy knows he's pitching the 8th with a small lead or maybe in a tie game. The closer knows he's got the 9th, etc. It's not easy to get geared up on a moment's notice without any idea at all if it might be your turn. That said, a manager shouldn't always stick to the script. If a different, fully capable pitcher possibly has a much better matchup brewing, get him tentatively ready. Just let him get casually loose and if the situation draws nearer, have him pick up the pace so he can be all set to go. I also still don't get why they didn't IBB Ramirez to load the bases with one out. Now you set up the force at home and a possible DP with Soto at the plate.
