On the radio broadcast, they mentioned that the sod patches are placed down brand new for each match coming from south jersey. They said it in a way that inferred that at Yankee Stadium they don't do it that way. I'm not sure if they keep it outside on trays in the sun nearby for Yankee stadium, and just bring it in and place it down while prepping the field or something.2. Citi field inlay is awful. Idk what they do to it but it's not good.
At City Field, my guess is that they (the sod patches) are trucked in from a few hours away after sitting stacked on top of each other in pallets, so they are in a much worse shape when layed. It would normally take several days for them to recover from that.
Just guesses based on the pbp comments.
