The Curveball Club

Boston, MA · Est. 2026

The Curveball Club started with a simple frustration: adult baseball leagues require too much commitment. Season rosters, mandatory games, league dues, weekly emails from a commissioner named Doug. None of that fits into an adult life that already has too many obligations in it.

We wanted to play real baseball, with proper rules and actual competition, without signing our summer away. So we built a structure that made that possible: pay per game, pick your night, claim your role, and show up.

The social part was intentional from the start. Baseball is good, and baseball with people you actually like afterward is better. That's why every chapter has a spot nearby where people tend to gather once the game wraps up. Nobody's required to go, but most people stick around.

The Format
  • $20 per game, or $200 for the full season
  • 40 players per night, split into two sides
  • No walks, swinging strikes only, 5-run inning limit
  • Neighborhood fields across Boston, scheduled around permit availability
  • Optional hangout after: every chapter has a spot nearby if you want to stick around

Each chapter is rooted in its neighborhood, with its own field and its own regulars. Games are scheduled around park permit availability, which keeps the schedule flexible and the club from being locked into any single location. When a permit is confirmed, a game slot opens.

The club is organized as Curveball Sports League LLC, a Massachusetts limited liability company. We carry insurance, take safety seriously, and run a clean operation.

The role board system, where each player picks their position before game day, was designed to give people agency and cut down on the awkward “who's playing where” conversation that eats the first 20 minutes of every pickup game. You pick your spot, you own it, and we play ball.

If you've been looking for a reason to dust off your glove, this is it. There are no tryouts, no roster spots, and no commitment beyond showing up.
