BARCELONA, Spain — Fourth-seeded Kei Nishikori reached the quarterfinals of the Barcelona Open by beating Andrey Golubev of Kazakhstan 6-0, 6-4 Thursday.

Nishikori had been sidelined by a groin injury since beating Roger Federer last month.

Russian player Teymuraz Gabashvili followed up his win over fifth-ranked David Ferrer with a 6-4, 6-2 victory over another Spaniard, Inigo Cervantes, to reach the quarterfinals. Ernests Gulbis of Latvia also won.
