Hongkonger serves up another upset at Flushing Meadows with defeat of world No 85

Coleman Wong served up another upset at the US Open on Thursday, beating Adam Walton in four sets at Flushing Meadows.

The Hongkonger reeled off 21 aces and 54 winners in an impressive performance on the Billie Jean King Tennis Centre’s outer Court 10, triumphing 7-6, 6-2, 4-6, 6-4 in three hours.

It was another big scalp for Wong, who lost to Walton at the same stage of the Miami Open in March and is ranked nearly 100 places below the world No 85 Australian.

The first man from Hong Kong to win a grand slam singles match since the Open era began in 1968, Wong will face Russian 15th seed Andrey Rublev in the third round on Saturday.
