PEC Zwolle have won their first away game of the new Eredivise season with a comfortable 3-0 victory over De Graafschap.
The home side started promisingly, but lost Dean Koolhof in the opening period as he suffered a serious looking injury and had to leave the pitch on a stretcher.
They couldn't turn their pressure into goals and were made to pay by a rampant Zwolle after the break.
The visitors took the lead through Wouter Marinus, who converted Queensy Menig's cross from close range and doubled their advantage 11 minutes later as Bart van Hintum beat the keeper with a powerful low strike.
Graafschap defender Thijs Bouma gifted the away side a third when his weak back-pass was seized upon by Sheraldo Becker, and he slotted the ball into the back of the net to send Zwolle second in the standings.
