Jimmy Floyd Hasselbaink put Saturday's opponents Blackburn Rovers to the sword with a magnificent hat-trick back in October 2004.
The Dutch marksman was enjoying a fine start to his Boro career with four goals in his first eight appearances after joining from Chelsea.
And he produced a finishing masterclass in this trip to Ewood Park with a second-half hat-trick that earned Boro victory.
Jimmy pounced with three typically lethal finishes against the ten men of Rovers - who had Turkish midfielder Tugay dismissed - with countryman George Boateng also notching a rare goal for the Teessiders.
