MELBOURNE, Australia (AP) — Spectators booed an injured Novak Djokovic as he left the court in Rod Laver Arena after quitting one set into his Australian Open semifinal against Alexander Zverev on Friday.

The 37-year-old Djokovic packed up his equipment and walked off toward the locker room, pausing to respond to the jeers by giving two thumbs-up.
