Major League Baseball and FanDuel on Thursday announced a multi-year agreement that makes the sportsbook operator an official gaming partner of the U.S. professional league.

It is MLB’s first partnership with FanDuel, a unit of Flutter Entertainment PLC. FanDuel already has similar agreements with the National Basketball Association and its Brooklyn Nets team, as well as the National Hockey League and its New Jersey Devils team.

MLB has previously partnered with MGM Resorts International and DraftKings.

A series of league partnerships with sportsbook operators have been made as regulated sports wagering spreads across the United States.
