Matt Marolf, writer for UbiTennis, rejoins his neighbor Carl Bialik—host of Thirty Love—from an appropriate social distance to talk about Roger Federer's tweeted support for a WTA-ATP merger, speculate wildly (OK, that's mostly Carl) about what drove the move and what might come next, and discuss which member(s) of tennis's Murray family would make the best boss of tennis.  Have a suggestion for a Thirty Love guest? Email Carl at bialik@pm.me Music by Lee Rosevere: "Credit Roll" and "Glass Android."
