In-form Iceland international Alfred Finnbogason was again on the mark with a second-half strike that earned Heerenveen a 2-1 comeback victory at Heracles.
Heracles took a 26th-minute lead through Oussama Tannane but Marten de Roon had Heerenveen level within 10 minutes and then Finnbogason, the Eredivisie's top scorer, slotted home a 49th-minute winner for his 22nd league goal of the season.
The victory leaves Heerenveen in sixth spot, a point behind PSV Eindhoven in fifth, while Heracles remain in 11th place.
