Confident Frances Tiafoe 'flying high' after Tokyo opener
Japan Open on Monday. The American made a name for himself when he stunned Rafael Nadal on his way to a shock final-four appearance at Flushing Meadows last month before playing a starring role at the Laver Cup. The world number 19 is playing his first singles tournament since the US Open this week in Tokyo and he dispatched Japanese wild card Uchiyama with little fuss.
