What "contact play" means in baseball

"Contact play" in baseball refers to a specific strategy used by baserunners when there is a runner on third base and a batter at the plate. The baserunner on third base will remain close to the base while the batter hits the ball. As soon as the ball is hit, the baserunner takes off towards home plate, regardless of whether the ball is caught or not. This is done in order to force a play at home plate and increase the chances of the runner scoring.
