The casino group Caesars has teamed up with the Arizona Diamondbacks to launch a mobile sports betting app in Arizona.

The casino operator also announced plans to build a first-class sportsbook and bar concept on the plaza adjacent to the team's home, Chase Field.
The D-backs CEO, Derrick Hall, said: "Caesars is considered the cream of the crop and aligns with our philosophy when it comes to professionalism, brand presentation, and customer treatment and brings its best in class William Hill mobile sports book product and retail sports betting expertise.
"Equally important, we went through our strong due diligence to find the industry leader in the education and execution of responsible gaming."
The deal simultaneously grants Caesars Entertainment mobile sports betting market access and exclusive sponsorship in sports betting and daily fantasy sports for the D-backs. In tandem, Caesars also finalised a multi-year agreement with Major League Baseball (MLB) to become an authorised gaming operator of the league.
