Sammy Ameobi was also on target for Peter Beardsley’s side in a goal-laden first half at Leyland, the headquarters of Lancashire’s Football Association.
All six goals came in the first 45 minutes.
Ferreyra, signed on a season-long loan from Shakhtar Donetsk, was the star and the 23-year-old could now come into contention for Saturday’s game against Aston Villa at Villa Park.
NEWCASTLE UNITED: Alnwick, Barlaser, Ferguson, Olley, Williams, Satka, Roberts, Bigirimana, Ferreyra, Armstrong, Ameobi.
