It's 109 Degrees. Tennis, Anyone?

The heat finally suspended play at the Australian Open today, with extreme temperatures topping 109 degrees Fahrenheit (43 degrees Celsius). Players were left to ask, what took so long?

Implementing the Extreme Heat Policy for the first time since 2009, officials at Melbourne Park postponed all matches on outer courts until the evening and closed the retractable roofs to continue play on the show courts. The move came after days of grueling weather in which some players suffered from blackouts, hallucinations, vomiting and other symptoms of heat exhaustion.
