This lantern slide, taken from the side, shows two baseball players, one behind the other, in a baseball stance on a field. There are wooden stands surrounding the baseball field, and both of the players are wearing a uniform and hat. One player appears to be in the short stop position and the other player, the runner, has a sizable lead off second. The picture is not dated but it assumed to have been taken between 1920 and 1925. This picture shows the "daylight play," which is still used in baseball today. During this play, the short stop on the field determines when there should be a pick off at second base. As stated by Leslie Mann, the short stop should: walk up behind the runner, toss dirt and then go back and signal the pitcher. The short stop then walks up, and when the runner sways toward third, dashes for second base. The pitcher should turn when he sees daylight and throw the ball to the short stop on second. This play is one of the most effective pick off moves in baseball. This image is located in Leslie Mann's thesis, along with multiple other images of baseball players and this play. Mann's thesis and these pictures may have been used during the teaching of the baseball instruction course at Springfield College. The book used in the course was titled "Baseball Instruction Course" discusses the baseball theory notes based upon Leslie Mann's Mannscope Motion Picture Course and other materials assembled by Harold Stephen DeGroat. At this time, it is not known what Leslie Mann's Mannscope Motion Picture Course was. This book was written or assembled in 1935. The book includes freshman, sophomore, and coaching courses. The freshman theory looks at base running, batting, a defensive strategy, pitching, and base sliding and the methods on how to appropriately perform these actions during a baseball game. The sophomore theory discusses the catcher, first baseman, second baseman, third baseman, outfielder, a defensive strategy and a battery strategy and the requirements of each position on the baseball field. The coaching component talks about the Mannscope pitching reels notes and questions for references and discussion. Mann graduated from the International YMCA College, now Springfield College, in 1925. He planned to graduate with the class of 1914, however he took classes part time for several years so that he could play professional baseball. He played professionally for 19 years with Boston, Chicago, St. Louis, Cincinnati, and New York. At Springfield, he was the first freshman to make the varsity football team and was nominated for All-American honors, playing as a halfback on the field. Les Mann was the varsity baseball and basketball coach at Springfield in the mid-twenties. He later formed the first baseball school in the nation, and directed the first U.S. All-American baseball team in 1935. He was inducted into the Springfield College Athletic Hall of Fame on November 4, 1972.
