Slinger Bag, the new portable tennis ball launcher, has signed an exclusive partnership with Dahcor and its new Dahcor Tennis Center (DTC) in Sintra, Portugal. Dahcor, a company that specializes in the manufacture of customized tennis racquets, started operating in Portugal in January 2019. Its tennis center, which will have a soft opening at the end of July, is set to be the first tennis academy in the world to use artificial intelligence on its courts to help improve the player’s performance through an app connected with a racquet sensor, a smart court and a hawk eye. The 16-player residential facility will offer courses run by top ATP and WTA coaches. The Slinger Bag will be one of its outperformance teaching tools. Run by Mike Ballardie, a former executive of Wilson and VF Corp. who was most recently the chief executive of Prince, Slinger Bag has reached sales of more than $1 million since its launch a little over a year ago.
