Heerenveen moved fourth in the Eredivisie after a hard-fought 4-3 win over Roda JC.
In an action-packed match at the Abe Lenstra Stadio, the home side were ahead after five minutes with Bas Dost scoring.
Syrian striker Sanharib Malki then levelled just minutes later, but parity did not last long as Daryl Janmaat made it 2-1 to Heerenveen.
However, Roda battled back and goals either side of the interval from Malki and Davy de Beule gave them the lead.
Heerenveen, though, levelled on the hour through Gerald Sibon before Dost's second with 20 minutes left gave them victory.
The three points takes Heerenveen above Ajax and into fourth.
