Juventus forward Gonzalo Higuain scored a second-half hat-trick as the titleholders routed hapless Sassuolo 7-0 in Serie A on Sunday. Alex Sandro gave Juventus a seventh-minute lead, then two goals in three minutes from Sami Khedira put the Turin side three goals up and Miralem Pjanic added a fourth before halftime. Higuain then burst onto the scene with a hat-trick between the 63rd and 83rd minutes. Juve's seventh consecutive league win took them top of Serie A, at least for a few hours, with Napoli away to Benevento in the evening game. Juve have 59 points to Napoli's 57. AS Roma ended a six-game winless run in the league when Cengiz Under scored after 43 seconds, winning possession and then firing home from outside the area, to give them a 1-0 win at relegation-threatened Verona. Fifth-placed Roma held out despite having Lorenzo Pellegrini given a straight red card six minutes after halftime for a late, reckless tackle on Ryder Matos. AC Milan were held 1-1 at Udinese after having a player sent off and then conceding an own goal. Suso rifled Gennaro Gattuso's team ahead in the ninth minute with a 30-metre shot but the visitors were reduced to 10 men when Davide Calabria was sent off for a second booking in the 68th minute. Udinese equalised eight minutes later with a Kevin Lasagna shot which deflected off a defender before goalkeeper Gianluigi Donnarumma tipped it into his own goal.
