Tennis quality was low but the atmosphere was electric. I have to admire Kyrgios' competitive spirit. Nobody thought at 5-7 4-6 that he would come back, including Kyrgios himself. Then he got help from Seppi, I talk about it in detail in my latest write-up. For the sake of the tournament, I am glad that he won. Kyrgios-Murray will generate more excitement than Seppi vs. Murray anywhere, especially in Melbourne. Putting the match on Hisense Arena got some criticism but people forget that Kyrgios called it his favorite court, and that ground ticket holders had access to that court. They deserve to see a singles match too (not that many got to, apparently there were lines of 2+ hour-long prior to the match's start, wanting to get in).
Nadal is cruising through, he could not have asked for a better draw. Anybody who could have given him trouble in the early rounds got dispersed to other parts of the draw, and now he has played himself into form to take on the Murrays and Djokovics or Wawrinkas..
