rubber part that'll be replaced
What is this?
If OP is correct in saying the "rubber warning track" will be replaced, I'm assuming he's talking about the surface between the field and dugouts. Find a picture to see what I'm talking about. It's not dirt, grass, or turf, just a rubber surface.

And the only reason I can think of for it being replaced with artificial turf instead of grass is the sunlight issue, since that area is so close to walls and likely to be shadowed.
