Siniša Mihajlović chose to line up with arguably his strongest available eleven as Salvatore Sirigu, Nicolas N'Koulou and Alex Berenguer all made debuts.
Toro were ahead after only thirteen minutes as Adem Ljajic's excellent through ball found Andrea Belotti, and il Gallo slid the ball past Richard Marcone to open his account for the season.
However, Trapani were surprisingly level five minutes later when defender Pasquale Fazio headed home at the near post from a corner. However, Fazio then diverted Belotti's cross into his own net as Toro quickly regained the lead.
Spanish winger Alex Berenguer scored a debut goal after rounding the keeper, whilst Belotti and Joel Obi both scored before the break to give Toro a 5-1 half time lead.
Iago Falque volleyed home a lovely Adem Ljajic assist to score a sixth, whilst substitute Lorenzo De Silvestri scored from an acute angle in the closing minutes to give Toro the perfect start to the new campaign.
