I am not making myself clear. Nixon is the one who needs a warmup inning in Omaha, before he has to come in on Thursday evening with the bases loaded and the tying run on 2nd base. Had he pitched the one inning today, he would have felt very comfortable in the environment. Meanwhile, by the time we get to Thursday all of the batters for all of the teams are used to the ballpark.
The exceptionally smart coach is a coach who can prepare his team for future situations while at the same time winning the present game. Witt is not available for an unknown number of games, but would have been available sooner had he not pitched the ninth. Nixon is available Thursday and would have still been available Thursday if he had pitched today. Nixon will be available Thursday, Friday, etc. for one inning, because he is the closer.
My position is that the exceptional coach could have preserved more of Witt for future games while at the same time making the transition much easier for Nixon in his first game out of the pen. I am an optimist, we are going to a Friday game for sure. I am not giving Pierce an F, simply a missed opportunity, call it a B+ instead of an A. It doesn't make much difference, unless Nixon comes out cold on Thursday or Friday night and has trouble.
If Nixon has trouble on Thursday or Friday, we're almost certainly done.
