The shadow is pretty circular near the center of the eclipse. If you look at the map, the bumpiest parts are far from the center where the shadow is elongated due to it hitting more to the side of the Earth's sphere. You'd see an oval if the Earth and moon were perfect spheres. But any irregularity on the moon gets stretched out, and irregularities of the Earth's surface add to it even more.
