Australian Bernard Tomic fired nine aces past Alexandr Dolgopolov in ousting the fourth-seeded Ukranian 6-1, 7-5 Thursday to reach the ATP Memphis Open quarter-finals.
The German-born 22-year-old dispatched 23rd-ranked Dolgopolov in only 66 minutes to book a date in the final eight against the winner of a later match between Americans Donald Young and Denis Kudla.
Tomic, who ousted Dutchman Igor Sijsling in the first round, did not face a break point in ripping through the opening set and rescued seven of eight break-points against him in the second.
Tomic, ranked 49th, improved to 3-5 all-time against Dolgopolov with his first win outside Australia. He had won their most recent prior matchup in last year's Sydney quarter-finals and in a five-set battle in the third round of the 2012 Australian Open.
Other Thursday matches in the $585,000 (512,000 euros) indoor hard-court event find South African second seed Kevin Anderson facing Aussie Sam Groth and US sixth seed Steve Johnson meeting Germany's Dustin Brown.
