By Leesa Smith for Daily Mail Australia Nick Kyrgios managed to override his emotional outbursts to defeat classy Russian Mikhail Youzhny on his Flushing Meadows main-draw debut at the US Open but admits he needs to curb his on-court antics. Kyrgios backed up his Wimbledon slaying of Rafael Nadal in a stirring 7-5 7-6 (7-4) 2-6 7-6 (7-1) victory over the world no.23 player on Monday with an impressive 26 aces and 68 winners in the four-set demolition. But the 19-year-old Australian stood just one point away from being forfeited after being hit with three code violations during the tense and high-quality three-hour encounter on Show Court 17.
