Jack Sock and
John Isner have nothing against pickleball and both of them will play in the Pickleball Team Championships.
There has been an ongoing debate between tennis and pickleball as the latter sport gains more popularity in the US. We've seen many players come out in support of the sport that has a portion of tennis fans pretty annoyed.
Just a day ago there was a debate on Twitter between several current and former players about the sport but Isner has already played in pickleball charity events before with Jack Sock following him in this competition.
