Welcome to the Keystone Base Ball Club of Harrisburg!

---

Based in Harrisburg, PA, our team plays 19th-century base ball to celebrate and preserve the history of America’s pastime. As a proud member of the National Association of Historic Base Ball Clubs (NAHBBC), we welcome fans and newcomers alike to join us in experiencing the game as it was originally played.

The Keystone Base Ball Club is dedicated to bringing the spirit, sportsmanship, and traditions of early base ball back to life. Our players take the field using the rules, customs, and style of play from the 1800s—when the game was spelled “base ball,” gloves were unheard of, and the focus was on gentlemanly competition, teamwork, and community. From the vintage uniforms to the authentic gameplay, every match offers a step back in time for players and spectators alike.

Whether you’re a lifelong baseball fan, a history enthusiast, or simply looking for a unique family-friendly event, a vintage base ball match is an experience unlike any other. We regularly participate in exhibitions, festivals, and historic events throughout the region, sharing the rich story of how the game evolved into the sport we know today.

The Keystone Base Ball Club is more than just a team—it’s a community of players, supporters, and historians who are passionate about keeping this piece of American heritage alive. We invite you to come watch a match, cheer from the sidelines, ask questions, and become part of the experience.
