Premier Lacrosse League

The Premier Lacrosse League (PLL) is the professional field lacrosse league of North America, founded in 2018 by brothers Paul and Mike Rabil and headquartered in El Segundo, California.

Games are carried by ESPN, ESPN2, ABC and ESPN+, and investors include The Chernin Group, The Raine Group, Arctos Partners and ESPN itself. Digitally the league runs a Next.js web property with an Apollo GraphQL API behind it (premierlacrosseleague.com/api/graphql), a dedicated stats site, iOS and Android apps, and a Shopify-hosted merchandise store that publishes an llms.txt, a Universal Commerce Protocol (UCP) profile and an MCP endpoint for agent-driven commerce.
