Ferrer storms into last eight
David Ferrer did not face a single break point as he beat Leonardo Mayer
Top seed and former champion David Ferrer cruised into the quarter-finals of the Unicef Open in s'Hertogenbosch with a one-hour demolition of Argentina's Leonardo Mayer.
The Spaniard, who won the title in 2008, did not face a single break point against him and converted all four of those on Mayer's serve to come through 6-3 6-1 and book a last eight meeting with local favourite Igor Sijsling.
Wild card Sijsling, ranked 112 in the world, came through two tight sets against Belgian veteran Olivier Rochus, breaking twice as he inched home 7-5 7-6 (7/4) in 86 minutes.
Third seed Jurgen Melzer was a surprise casualty, falling 6-2 6-2 to Japan's world number 70 Tatsuma Ito, who will next face Frenchman Benoit Paire, a 6-3 0-6 6-4 winner over Poland's Lukasz Kubot.
Germany's Philipp Petzschner received a walkover against Croatian Mate Pavic and will next play Edouard Roger-Vasselin, while Gilles Muller and Xavier Malisse were the day's other winners.
