Nick Kyrgios has been fined $US14,000 ($A20,700) for unsportsmanlike conduct after his racquet-smashing exit from the US Open.
Kyrgios slammed multiple racquets to the court in frustration following his 7-5 4-6 7-5 6-7 (7-3) 6-4 loss to Karen Khachanov in the quarter-finals on Tuesday night.
The Wimbledon runner-up racked up a total of $US32,500 ($A47,500) in fines while at Flushing Meadows, getting penalised five times.
He still came out well ahead however, having earned $US473,200 ($A701,700) in prizemoney at the year's final grand slam tournament, where he also reached the doubles third round with countryman Thanasi Kokkinakis.
