UDINE, Mar 19 (SW) - Behind leaders Juventus, the top four teams in Italy all were victorious on Sunday in Serie A as AC Milan, Inter Milan, Fiorentina and Roma all claimed full points.

Udinese - AC Milan 0-4

Knocked out of the UEFA Cup during the week, Udinese were simply knocked out on Sunday as they fell to a heavy defeat the hands of AC Milan.

Andriy Shevchenko gave the Rossoneri the advantage in the 42nd minute as they finally broke down a stubborn Udinese defense, and Alberto Gilardino doubled the advantage on the half-hour mark to make it 2-0.

Inter Milan - Lazio 3-1

Third-placed Inter kept pace with their city rivals AC Milan, taking the lead over Lazio in the 37th minute when Alvaro Recoba did well to set up Luis Figo for the the 1-0 lead.

Recoba himself made it 2-0 to Inter just after the second-half restart, but Goran Pandev pulled one back for Lazio just eight minutes later.

Recoba, though, got that goal back for Inter in the 72nd minute to complete his brace and the Nerazzurri claimed all three points.

Fiorentina - Ascoli 3-1

After beating Roma last weekend, Ascoli were riding a high going into their match at Artemio Franchi against Fiorentina, and a header by Maurizio Domizzi two minutes before half-time sent them into the break up by a goal.

That lead was erased on 53 minutes when Christian Brocchi equalized for Fiorentina, and the home side really found their stride after Gianluca Commotto was sent off in the 76th minute for his second yellow card.

After that, Luca Toni punched the back of the net in the 82nd minute and Giampaolo Pazzini did likewise two minutes from the end.

Fiorentina are one point up on Roma in fourth place in the league with a game in hand.

Roma - Messina 2-1

After an embarrassing loss to Ascoli a week before, Roma jumped out to a lead and then held on to defeat Messina at Stadio Olimpico.

Simone Perrotta fired the Giallorossi in front after just seven minutes, and they held that 1-0 lead until Alberto Aquilani made it 2-0 with 56 minutes played.

Arturo Di Napoli kept hope alive for Messina in the 68th minute when he pulled a goal back, but the loss saw the Sicilians slip into the relegation zone.

Chievo - Siena 4-1

Lecce - Parma 1-2
