On days that the Cubs had a strong showing at the gate, fans would be allowed onto the field... behind the plate and along the outfield fences and were actually in play. This shows one major difference between the game during the 19th and early 20th century and today. The very tall wooden fences stood 340 feet out to left, 560 out to center and 316 out to right. Home Runs however during this time were not yet part of the game as Babe Ruth is the one who brought power to the ballparks, so a ball leaving the yard wasn't something that happened very
often. The game during this time was more about "small-ball"… doubles, triples and the stolen base. There are still some players who scored in the double digits in the Home Run department but most of these were of the inside-the-park HR variety... not the fence clearing blast.
