- Ivan Ilic (43')
An even first half took a turn two minutes before half-time when Torino went ahead through Ilic who struck low from outside the box.
Torino, winless in their previous four games, moved up one place to 10th on 42 points.
Lazio remain second on 61 points, two above third-placed Juventus who returned to the top four after their 15-point deduction over the club's transfer dealings was scrapped on Thursday.
