This discussion has triggered memories of how my son's playoff games went. They played a DH. First game he was playing RF, late innings he tried to make a play on a fly ball missed it and it turned into a double, but the team was already down by a football score. Next game he was a DH. They kept his bat and he did deliver a HR to tie the game late but the team could not hold on and gave up a run in the bottom of the inning and eventually lost. Son learned the hard way about playing time margins, imo made him a better person because of the unfair and cold nature of playing time that can be applied to the real world, plus no one cares. At least he had a strong hitting performance in that series that ended their season, again no one cares.
