What is the curious characteristic of cricket?

The curious characteristic of cricket is that the length of the pitch is specified – 22 yards – but the size or shape of the ground is not. Most other team sports, such as hockey and football lay down the dimensions of the playing area: cricket does not. Grounds can be oval like the Adelaide Oval or nearly circular, like Chepauk in Chennai. A six at the Melbourne Cricket Ground needs to clear much more ground than a lofted shot for the same reward at Feroz Shah Kotla in Delhi.
