Six-goal Suarez fires Ajax to 14-1 win
Suarez, who helped Uruguay qualify for next year's World Cup in South Africa, scored twice in the first half and added four more after the break as Ajax ran riot to reach the last eight.
The result was a Dutch Cup record for Ajax, whose previous best was a 10-0 win over Rapiditas Weesp in 1961. NAC Breda hold the overall record with an 18-1 win over Dongen in the 1950s.
