Play was suspended for three hours at the Australian Open on Tuesday afternoon because of extreme heat.
With the temperature into the mid-30s, the tournament’s heat stress scale, which also takes into account humidity and wind speed, hit five just after 2pm, meaning play was stopped on the outside courts.
Among those affected was British number two Dan Evans, who had just taken a two-sets-to-one lead over Argentina’s Facundo Bagnis in the first round.
It took until 5pm for conditions to improve sufficiently for play to resume on the outdoor courts.
Tuesday was forecast to be the hottest day of the tournament, with the possibility of thunderstorms and cooler temperatures from Wednesday.
