MELBOURNE, Jan 17 (Reuters) - Scorching heat halted outdoor matches and sent fans scurrying for shade at the Australian Open on Tuesday as players were given an early test of their endurance on a sweltering day two at Melbourne Park.
The tournament's Heat Stress Scale, which measures radiant heat, humidity and air temperature in the shade, crossed its highest threshold of 5.0, halting 10 outdoor matches at the Grand Slam.
Organisers said play on outdoor courts would not resume before 5 p.m. local time (0600 GMT).
"I think I did well to manage my emotions, and then especially manage the heat, try not to get too hot-headed," Fernandez told reporters.
Extreme heat is a feature of the Australian Open, held in mid-summer in the country, with play occasionally suspended and leaving organisers with scheduling headaches.
