ChabDog’s Aussie Open Conversation Openers (Day 10, Quarterfinals):

• After coppin some serious Z’s in the 1st set, Zverev comes roaring back to overwhelm a visibly spent Wawrinka.  If he continues to serve like this, might there possibly be a chance for him to go all the way … in which case he can deliver a pretty hefty check into the coffers of the Brush Fire relief fund.  This young star is not only a generous humanitarian … he’s also got serious charm and great sense of humor, as displayed in his post-match interview with Johnny Mac.
• No dice for Milos in his abortive bid to knock out No. 2 Novak.
• Simona says goodnight to Kontaveit.
• Muguruza muzzles and puzzles Pavly with an impressive, all-court display of power and accuracy.
