Miami Open: Nick Kyrgios stuns Andrey Rublev in 52 minutes
Nick Kyrgios stressed Friday he's at peace with himself after a day where both sides of the Australian's character come into sharp focus at the ATP and WTA Miami Open. Hours before he wowed Hard Rock Stadium with a ruthless 52-minute demolition of seventh-ranked Andrey Rublev to reach the third round, the enigmatic world number 102 was fined $25,000 by the ATP following a stormy defeat to Rafael Nadal at Indian Wells earlier this month.
