Brazilian forward Amauri scored in the 48th minute to lead Juventus over Torino 1-0 Saturday for its first league victory in more than a month.
Amauri dribbled by a defender and scored his fifth goal of the season in the Turin derby with an angled shot, aided by a poor saving attempt by goalkeeper Alex Calderoni, who was filling in for injured Matteo Sereni.
Juventus was also missing its first-choice goalkeeper, Gianluigi Buffon, and several other starters as well. Calls were being made for coach Claudio Ranieri to lose his job following a loss to Napoli last weekend, but now Juve has won two big games in five days _ including its 2-1 victory over Real Madrid in the Champions League on Tuesday.
Juventus hadn't won in the league since beating Cagliari 1-0 on Sept. 21.
With 12 points, Juventus moved back into the top half of the table.
Also, Catania drew 1-1 at Siena to move within one point of league-leader Inter Milan, which hosts Genoa on Sunday.
Inter leads with 16 points.
Second-half substitute Emanuele Calaio put Siena in front in the 75th minute, heading in a cross from Cristiano Del Grosso.
Three minutes later, Catania was awarded a penalty kick when Siena goalkeeper Gianluca Curci tripped forward Michele Paolucci following an ill-advised backward pass from Calaio. Giuseppe Mascara converted the spot kick to equalize.
In Sunday's other games, surging AC Milan is at Atalanta, Udinese hosts struggling AS Roma and Lazio plays Napoli.
