NEW YORK (REUTERS) - Russian Daniil Medvedev made quick work of second-round opponent Dominik Koepfer 6-4 6-1 6-2 on Wednesday (Sept 1), soaking up the cheers of the US Open crowd to keep his bid for a maiden Grand Slam title alive.

The world number two broke his German opponent's serve to kick off the match but Koepfer levelled with a break in the seventh game, helped by one of two Medvedev double faults in the opening set.
