Your scenario is near impossible, but most scenarios trying to illustrate a point are. But the answer to your question is one of the easiest. the most any pitcher can do for his team is WIN. A win for the pitcher is a win for the team, every time. The same for a loss. A loss for a pitcher is a loss for the team. Any pitcher won goes 30-0 has helped his team succeed to the highest degree. A pitcher who goes 0-20 has hurt his team to the worst degree. Again coming down to winning, the pitcher that helped his team is by far the best.
