MELBOURNE, Australia — After bowing out of the Australian Open this week, Jack Sock and his childhood friend and doubles partner, Jackson Withrow, ended up on opposite sides of a great divide.
Withrow’s childhood dream was to play professional tennis; doubles proved to be his only portal.
Sock, the world’s second-ranked doubles player, has an Olympic gold medal from 2016 that he won in the mixed event, which led to his being honored at a University of Nebraska football game and throwing a ceremonial first pitch at a Kansas City Royals baseball game.
