A second-half salvo earned Udinese all three points with a 3-0 win over the 10 men of Inter Milan at the Stadio Friuli.
Antonio Di Natale was on target twice with Luis Muriel also scoring for Francesco Guidolin's side, who were aided by a red card for Juan Jesus in the 65th minute.
The win lifts Udinese up to eighth in the table, level on points with AC Milan, who have a game in hand, while Inter remain in fourth.
The game came to life after an even first half which included a good chance for the home team and a penalty appeal for the visitors.
That came in the 25th minute when Rodrigo Palacio fell as he passed Maurizio Domizzi, but the referee booked the Inter forward for diving.
Two minutes later, Di Natale rattled the crossbar with a direct free-kick from 30 yards with Samir Handanovic well beaten.
Inter should have taken the lead in the 50th minute when Antonio Cassano and Palacio combined to set up Jonathan, but he contrived to send a shot wide of an open goal from just a few yards out.
The game then turned in the space of two minutes with Di Natale putting Udinese in front in the 63rd minute, waiting for the ball to drop before firing it low into the far corner, then Juan was sent off for a second yellow card.
Dusan Basta set up Muriel to make it two for the Bianconeri 10 minutes later, with Inter's hopes of a recovery vanishing.
In the 79th minute, Di Natale bagged his 12th of the season, stealing in ahead of Esteban Cambiasso to meet Giovanni Pasquale's low cross from the left and finishing in typical goal-poaching style.
Just to prove that it was not Inter's day, Palacio was put through on goal in the 82nd minute, but Danilo got back with a fine sliding tackle to take the ball away from him just as he was about to shoot.
