A pair of former Major League Baseball senior executives are returning this summer to big-league ballparks – but with pickleball.

Mike Dee, who previously held senior-level business roles with the San Diego Padres and Boston Red Sox, and former MLB Advanced Media president and chief executive Bob Bowman are bringing their Pickeball4America to three MLB stadiums in July and August.

The newly formed entity, operating with the consumer-facing brand Pickle4, will stage its Ballpark Series at Fenway Park in Boston on July 13-16, San Francisco’s Oracle Park on July 20-23, and Denver’s Coors Field on August 3-6.

Rather than competing directly against other professional leagues in the fast-growing sport, Pickleball4America has developed a hybrid format for its events combining both amateur and professional play, tapping heavily into the recreational element that still represents pickleball’s foundation. The Ballpark Series will include multiple ways for amateur players to participate.
