McEnroe’s ‘Court 21’ barb after Navone’s Djokovic upset stirs debate
John McEnroe drew backlash by quipping that Mariano Navone’s post-upset turn on Court 21 would come in the next round after Navone stunned Novak Djokovic in five sets at the US Open. The win marked Djokovic’s first-round exit from a Grand Slam since 2006, and Navone advances to face either Berrettini or Wawrinka in the second round.
