Dunlop has announced a new, five-year partnership with the Association of Tennis Professionals (ATP) that will make it the Official Ball of the ATP Tour and the Nitto ATP Finals beginning in 2019. The U.K.-based brand will also become a Silver Partner of both of the ATP Tour and the Nitto ATP Finals. Dunlop already boasts an extensive presence across the sport, including a gold partnership with the Next Gen ATP Finals, which began in 2018. The company has also recently entered into a similar agreement, in effect since Jan. 14, with the Australian Open to supply the tournament's official ball.
