Kyrgios carving reputation as master of surprise

PARIS - If unpredictability is a weapon on the court, no player possesses a more potent threat than maverick Nick Kyrgios, the 22-year-old Australian who divides opinion like no other.

Capable of exhibiting sublime artistry and brutal power - sometimes in the space of two strokes - Kyrgios has been touted as a future Grand Slam champion from the moment he dismantled Rafael Nadal at Wimbledon in 2014 as a wild card.

Sadly, it has often been the foul mouth, the stroppy sulks and the occasional bouts of tanking that have grabbed most of the headlines - until this year that is.
