How does Bernard Malamud use imagery in The Natural?

Imagery:

“Wonderboy flashed in the sun. It caught the sphere where it was biggest. A noise like a twenty-one gun salute cracked the sky. There was a straining, ripping sound and a few drops of rain spattered to the ground. The ball screamed toward the pitcher and seemed suddenly to dive down at his feet. He grabbed it to throw to first and realized to his horror that he held only the cover. The rest of it, unraveling cotton thread as it rode, was headed into the outfield.”
