The message evident in the field becoming a place for second chances is that redemption is possible. The baseball field becomes a place where individuals who come to it find their second opportunities. In a world where material reality is so determinant of success and in which the temporal almost becomes transcendent, Ray's baseball field is a reminder that one can find elements of transcendence in the temporal world. These elements become the basis for our redemption, our second chances.
Salinger gets a second chance to enjoy the game he loves. Shoeless Joe and the other Black Sox scandal get a second chance to revel in their being. Ray gets a second chance to rediscover the connection with his familial identity. Doc Graham gets a second chance to be who he yearned to be. Those who come to the field are ones who lack a sense of peace, and while it is "money they have," redemption is what they are missing. There can be some elements in our world that are universal, from which redemption is a well- spring that has to be revered. It is why "people will come" and why easing one's pain becomes essential aspects of the narrative. Kinsella is suggesting that we keep our eyes open for these reservoirs of transcendental redemption, worshipping them when we see them for they are rare. Yet, when they are discovered, our world is transformed from what is to what can be, just like the characters who interact with Ray's field.
