Jim Chairusmi, who writes and edits sports articles at The Wall Street Journal, rejoins Thirty Love host Carl Bialik from the US Open to share ideas for how to expand the sport, from tiebreaks at 4-4 to reaching the platonic ideal of two-hour matches to 3-on-1 against Novak Djokovic. He also makes his title picks.
