Charlie Blackmon has agreed to a partnership with MaximBet that will have the Colorado Rockies outfielder appearing as a brand ambassador in marketing campaigns, promotions and social media content and at fan events for the online sportsbook.

Blackmon becomes the first active Major Leaguer to endorse a bookmaker in the United States.

Per Major League policy, Blackmon is not allowed to promote betting on baseball specifically but can endorse the sportsbook in general.
