Long way to go, but Mayer is a set up against Nadal; come on mate, you can do it.
All four US women won their Q/F's.
Nick Kyrgios was booed off court at the Shanghai Masters after going through with a threat to quit his match if he lost the first-set tie-break. The Australian lost the tie-break 7-5 to Steve Johnson soon after receiving a warning for smashing two balls out of court in frustration at a line call. He was also given a point penalty for an audible obscenity in the first-round match. At the same tournament last year he was fined for his behaviour and banned. The 13th seed was heard to say he would quit against Johnson if he lost the tie-break and, after his opponent served an ace on his first set point, Kyrgios walked over to shake hands.[size=78%][\quote][/size]
