Weather is a part of sports that most fans understand and tennis players must consider in their training, but theAustralian Open is going through a heat wave that is testing the limits.
In the first week of average 108 degrees, one player Frank Dancevic from Canada collapsed and hallucinated while China's Peng Shuai vomited then cramped and had to be helped off the court.
Jo-Wilfried Tsonga had the soles of his sneakers melt as Caroline Wozniacki melted the bottom of her water bottle while Jelena Jankovic burnt her own bottom on a seat.
So far discussion has not been so much about tactics and scores as much as who is surviving and who is dropping out. Only major upset has been the exit of Juan Martin Del Potro. All the other top seeded players have survived as expected.
American player Varvara Lepchenko, in 110 degrees and after trying to cool off, ended up losing 6-4, 6-0, 6-1. As she crawled off the court with a ice filled towel on her head, commented,
"This is just too much," she said. "They definitely should have just not started the matches in the first place, and same goes for a couple of days ago."
Forecasters are calling for the temperatures to drop in the next couple of days. Hopefully the focus of the Australian Open will get back to tennis and away from endless references to heat.
Until then, look at some pictures what the oven "down under" has cooked.
