Ajax won in league play on Saturday by 2-1 over RKC, and now had the most opportunities in the first half. The Amsterdammers had their moments through Brian Brobbey, Kenneth Taylor and Devyne Rensch, but could not find the back of the net.
Nine minutes before the break, AZ did find the mark. Wouter Goes scored with a header off a corner across the goal to the far post. Ajax claimed a foul, but the referees did not agree.
In the second half, both teams hit the aluminium. Sven Mijnans hit the crossbar, while Bertrand Traoré hit the post for Ajax.
The decisive blow came a minute before time. Mexx Meerdink found a pass in front of Remko Pasveer and lobbed the ball into the Ajax goal: 2-0.
