Like most athletes who compete in outdoor sports, baseball players wear shoes bristling with cleats (or spikes) to give them traction on the soft ground. Before they step up to home plate, batters usually trek through the soft dirt surrounding the on-deck circle (where they warm up). By knocking each shoe with the bat at home place, players shake the soil off their cleats, improving their traction for the mad dash around the diamond.
