Medvedev eases past Koepfer to reach Miami quarterfinals

Daniil Medvedev took another step towards retaining a title for the first time in his career as the Russian third seed beat Germany’s Dominik Koepfer 7-6(5) 6-0 on Tuesday to reach the Miami Open quarterfinals.

Medvedev overcame a shaky start and converted four break points while dropping serve just once to secure a spot in the last eight in Miami where he has yet to drop a set.

Koepfer was the early aggressor, using a pair of holds at love to build a 4-3 lead in the first set but Medvedev forced a tiebreak in which he lost the opening four points before finding his way.
