MILAN — Defending champion Juventus stretched its Serie A unbeaten streak to 46 games with a 2-1 victory at Siena Sunday. Claudio Marchisio scored what proved to be the winner for the league leader six minutes from time. Andrea Pirlo gave Juventus the lead with a trademark free kick in the 13th minute, but Emanuele Calaio leveled in first-half stoppage time, with Juventus looking lethargic. Pirlo also hit the crossbar with another free kick. Juventus coach Antonio Conte was given a rousing reception by the Siena fans as he took his seat in the stands. Conte led Siena to promotion in 2011 before quitting to take over Juventus. Conte saw his 10-month ban for match-fixing violations during his time at Siena reduced to four months on appeal this week. Also Sunday, high-flying Lazio cruised to a 3-0 win at struggling Pescara. Hernanes opened the scoring with a stunning 30-yard free kick in the fifth minute, and Miroslav Klose dribbled round Pescara goalkeeper Mattia Perin in the 25th to double Lazio's lead before scoring his fifth goal of the season with a powerful downwards header 10 minutes later. In the lunchtime fixture, American Michael Bradley scored his first goal for Roma in a 2-0 win against Atalanta. Stevan Jovetic continued his impressive start to the season as he scored his fifth goal of the season to send Fiorentina on its way to a 1-0 victory against Bologna. Luca Toni thought he had doubled Fiorentina's lead early in the second half but his header was ruled out for offside. Catania also got off to a good start in its 2-0 win against 10-man Parma as Alejandro Gomez gave it the lead with less than two minutes on the clock. Gonzalo Bergessio sealed the result 10 minutes from time and could have doubled his tally in stoppage time but his effort was disallowed for offside. Elsewhere, Cagliari's new coaches Ivo Pulga and Diego Lopez got their reign off to a perfect start, recording the Sardinian team's first victory of the season with a 1-0 win at Torino. The duo replaced Massimo Ficcadenti Tuesday. — Agencies
