Leslie Mann explains how when circling the bases, the runner should remain on as much of a straight path as possible which he shows through this diagram. When runners run from one base to another, the runner should attempt to remain in a straight line. If the runner runs outward towards the outfield, they actually have to travel farther to reach the next base. For example, if a player hits the ball into the outfield and runs from home plate to first base and then runs in a straight path line from first base to second base, this would be quicker than if the runner decided to run outside the base path by running outward towards the outfield. The slide shows how running outward means that eventually, you have to run back inward to actually reach the next base and tag it so it is a longer process than if the runner chooses to run in a straight line. The goal for the baserunner is to advance from one base to another as quickly as possible and this occurs if the straight path method is used. Also, if a runner is running outward rather than in a straight line, it would be harder to gain acceleration. The runner would have to slow down to run outward and would have to slow down again when they ran inward in order to tag second base, while the runner running in the straight line would continue to build his acceleration each step he took forward.
Poor condition;
The biggest issue with this lantern slide is two cracks run along the center of the image. The image has lines on it which represent the correct way of base running and the incorrect way of base running and the two cracks blend into the image like regular lines, which makes it difficult to distinguish the cracks on the image from the base running path lines Mann has drawn.
This digital image is made from two separate digital scans; one scan of the lantern slide (reflective); one scan of the image (transparency); the two image were then combined in Photoshop to create the final image.
