NEW YORK (Reuters) - Nick Kyrgios was a lightning rod for controversy at the U.S. Open this week but the fiery Australian was subdued after a third-round loss on Saturday and walked away quietly from the year's final Grand Slam.

Kyrgios did deliver a one-word jab at a line judge early in his straight-sets loss to Russian Andrey Rublev but otherwise steered clear of any of the sort of drama that he made headlines for earlier in the week.
