MELBOURNE, Australia (AP) — Novak Djokovic was about to respond to a question about Australian Open crowds when he paused, thought for a moment, and then asked an official if fans were still allowed into Melbourne Park for the year’s first major. That’s still the plan on the eve of the tournament: up to 30,000 daily — about 50% of capacity. Djokovic opens against Jeremy Chardy at Rod Laver Arena on Monday. Paying spectators will have to get familiar to the three-zone system in place to divide up Melbourne Park’s three main arenas. It’s all designed to assist with social distancing.
