Napoli beat Torino to cement second
Napoli took the lead in the 14th minute when Nicola Bellomo was adjudged to have tripped Dries Mertens and Higuain blasted the resulting penalty under the bar.
Torino was again furious when Napoli was awarded another soft penalty shortly after the half hour mark when Federico Fernandez's shot came off Kamil Glik's arm from point blank range. Higuain again converted, firing into the bottom right corner.
Torino's misery was compounded when halftime substitute Migjen Basha was shown a straight red card four minutes from time after hauling down Goran Pandev, who was clear through on goal.
Napoli moved two points behind Roma, which plays Udinese later.
