At Sportsman Park in St. Louis, Missouri, the St. Louis Cardinals players await a throw from the center fielder to home plate. The shortstop stands on the pitcher's mound with the pitcher backing up the catcher by standing behind him.
This slide represents the proper way to prepare to field a baseball thrown to home plate by the center fielder. The reason the center fielder would be throwing to home plate would be if there was a runner attempting to score, and the center fielder would throw the baseball to home plate with the intention of the baseball reaching home plate before the runner does. In this slide, the pitcher backs up the catcher and the short stop stands on the mound while the second baseman stands on second base. The reason this occurs is because the throw may be very difficult for the center fielder to make, and he might not have the arm strength to even make this throw. Because of this, having someone positioned at second base and the mound ensures that the throw will be fielded regardless of the arm strength the outfielder has. If the baseball had been hit to right or left field, the placement of the fielders would differ slightly. The goal is for the infield to make a straight line from the fielder to home plate with multiple stop points in between. If the ball was hit to left field, the first baseman would stand in the middle between first and second base with the short stop behind him at the mound to create this path, while if it was hit to right field, the shortstop would take the middle position and stand exactly where they usually stand while the second baseman would guard the mound.
Poor condition;
There is one crack running along the center of the image, and a few other noticeable cracks on the bottom right corner of the slide.
This digital image is made from two separate digital scans; one scan of the lantern slide (reflective); one scan of the image (transparecy); the two images were then combined in Photoshop to create the final image.
