Today was day 4 of the Australian Open in tennis. Many people don't care about it, but this day will be part of the story of sport, not only tennis, but in general. All because of this Power Shot.

The match was of the women's singles second round. 25th seed Barbara Zahlavova Strycova, from the Czech Republic, was to face Kai-Chen Chang, from Chinese Taipei. Not a match that caught all of the attention, it ended with Zahlavova's victory in less than 90 minutes. However, something happened in that match, something that will leave its mark in history, both in women's sport and overall. The Power Shot.

What is this Power Shot I'm talking about? A serve. But not a regular one, that is. A powerful serve. The measuring tool present on the court showed an outstanding 225 km/h, more or less 140 mph. This is not only the fastest serve ever recorded for a woman, beating the previous record by nearly 10 mph, but it also puts Zahlavova between the 50 fastest serves ever recorded in tennis history. An absolute feat, if you ask.

True is that this day, 22 January 2015, has been very prolific for fast serves. Two more female players broke the 125 mph barrier, while one male player was able to break the 150 mph barrier. Can these measurements be taken into account? Well, all involved players are known to have a good serve, so when risking everything at a life-or-death bet, they can produce miracles like this.

The Australian open still has many days of competition. Who knows if these statistics can be broken further. 

Wow, that sounds like an amazing feat though I really don't know much about tennis aside for a few players here and there, though I can already tell that 140 mph is extreme, and definitely something that needs to be remembered.
