Crop, as stated in the manual pages, crops to the extent of the object, for your purposes you may use raster::mask(), with the same syntaxis of crop mask function "Creates a new Raster* object that has the same values as x, except for the cells that are NA (or other maskvalue) in a ’mask’." You may pass inverse=T so you get those values out of the spatialPolygon.
