My context for this comment isn't just the heat. It's the first major of the year. It's the first time a lot of the men have played more than 3 sets since September. Some players have had more active offseasons than not. Then there's vacations, etc, etc.

Hell, at least it's not being played on the reclaimed tires anymore. That stuff would start getting sticky and players would get their feet caught causing ankle/knee issues.
