I can't see Kyrgios doing it. Kyrgios is very unlikely to make it past Murray just because of match-up reasons, Murray loves big serves and Kyrgios' own return is poor enough that Murray's own serves won't be as big a liability as they usually are. I'd be very surprised if that one went over 4 sets and frankly shocked if Kyrgios won.
Bouchard could potentially win just because the women's side tends to be so erratic that it's difficult to make predictions with confidence. Having said that, I'd rather she didn't, can't stand her.
I can't decide whether Murray's form is good or not. On the one hand, he made 2 unforced errors in the last 5 games of the match against Dimitrov, which is pretty incredible - it's easy to say Dimitrov choked but Murray was also incredible on the tight points. On the other hand, that should have been a 3-set match - the fact he didn't take the 2nd set was a bit shameful, up a break twice and loses both of them and then plays horrendously in the tie-break? Meh. Still, good that he was tested.
