Former finalist Alexandr Dolgopolov has booked a potential clash with Nick Kyrgios after brushing aside Horacio Zeballos of Argentina in the Brisbane International second round on Wednesday.

World No.38 Dolgopolov of Ukraine, ranked 28 spots higher than his opponent, was the first through to the men’s quarter-finals with a 6-1 6-2 win that lasted barely an hour at Pat Rafter Arena.

The 29-year-old Dolgopolov – the 2012 Brisbane finalist – will meet the winner of Wednesday’s second-round clash between third seed Kyrgios and fellow Australian Matthew Ebden.
