Nadal marches into last eight
Top seed Rafael Nadal booked his place in the US Open quarter-finals with a business-like victory over fellow Spaniard Feliciano Lopez at Flushing Meadows.
Nadal broke Lopez, ranked 23rd for the tournament, once in each of the three sets to record a 6-3 6-4 6-4 victory that showed him at his most professional rather than dominant.
