AMSTERDAM, Feb 9 (Reuters) - In-form Heerenveen held Dutch league leaders PSV Eindhoven to a 1-1 draw on Saturday to stay amongst the quartet trying to close the gap at the top.
Youngster Otman Bakkal gave PSV a dream start when he headed home a free kick from Balazs Dzsudzsak after 43 seconds.

Heerenveen stay third, also with 44 points, on goal difference above Feyenoord, 3-1 winners at Graafschap Doetinchem, and NAC Breda, who won 1-0 at home to Utrecht.
Lasse Schone netted a rebound after 17 minutes for Graafschap but on the stroke of halftime Roy Makaay replied for the visitors after a fine long pass from Leroy Fer.
Nick Hofs struck twice in the second half to seal Feyenoord's 400th away victory in professional football.
Rob Penders netted in the second minute to inspire NAC to victory over Utrecht, their sixth win in a row.
Remco van der Schaaf scored 15 minutes from time to earn Vitesse Arnhem a 2-1 home win over Groningen. Harrie Gommans opened the scoring before the break for Vitesse but Martijn Meerdink equalised 11 minutes into the second half.
Groningen slipped one place to sixth on 41 points while Vitesse moved up a place to ninth on 35 points only behind Utrecht on goal difference.
Seventh-placed Twente Eschede beat visiting Heracles Almelo 2-1 on Friday to move on to 39 points.
