Khachanov Leads 6-2 7-5 3-2 as US Open Quarterfinal Ends Early

Karen Khachanov moved through the US Open quarterfinals with the match ending in the third set, the Russian ahead 6-2, 7-5, 3-2 on New York's hard courts. The difference lay in what each man did behind his delivery: Khachanov landed only 54.5 percent of first serves but won a remarkable 88.9 percent of those points, and even his second ball held up at 63.3 percent. Alexander Blockx struck eight aces to Khachanov's six, yet won just 73.2 percent behind the first serve and 48.5 percent behind the second, with four double faults. For Khachanov, it was a return to the last four.
