Extreme heat triggered a five-hour suspension of matches on outside courts at the Australian Open on Saturday and briefly held up champion Jannik Sinner before he battled into the last 16.
Players and spectators roasted on day seven at Melbourne Park, where temperatures soared to 38C. The tournament has a Heat Stress Scale of 1-5, with five being the highest.
It hit five in the early afternoon, when the temperature was around 36 C, prompting the suspension of court play without roofs, which did not resume until after 7:00 pm.
