Rafael Nadal’s quest for a calendar Grand Slam remains on track after he breezed into the Wimbledon quarter-finals with a straight-sets victory over Botic van de Zandschulp.
Nadal, who was twice taken to four sets in the opening week of the tournament, needed two hours and 22 minutes to see off the world No25 6-4 6-2 7-6 (8-6), though he might have wrapped things up more swiftly had it not been for an uncharacteristic wobble when serving for the match at 5-3 in the third.
