MELBOURNE, Australia (AP) — A quick look at the Australian Open:

LOOKAHEAD TO TUESDAY

Rafael Nadal starts his bid for a men’s record 21st major singles title with a first-round match against Laslo Djere on Rod Laver Arena. The No. 2-ranked Nadal equaled Roger Federer’s mark of 20 by winning the French Open title last October, his 13th at Roland Garros. He has been experiencing stiffness in his back that kept him on the sidelines for Spain’s ATP Cup campaign last week and restricted his movement in practice. Sofia Kenin will start a Grand Slam title defense for the first time when she gets play started on the main show court at Melbourne Park against Maddison Inglis of Australia. Kenin won the Australian title last year and reached the final of the French Open. Other Grand Slam champions in action Tuesday include top-ranked Ash Barty, 2020 Australian Open runner-up Garbine Muguruza and two-time Australian Open winner Victoria Azarenka.

“I think every single person there was probably in awe to be sitting at a sporting event, as much as I was to have them there.” — Venus Williams, on having a sizable number of people back at Melbourne Park.
