Inter Milan scored four times in a 12-minute spell either side of halftime and added another couple late on to rout Lazio 6-0 in a lopsided contest of Serie A title contenders on Monday.
Lazio started the game without regular defender Alessio Romagnoli and Samuel Gigot replaced center half Matias Gila midway through the first half.
When Gigot was forced off at halftime coach Marco Baroni was forced to reshuffle his back four again but the lack of experienced heads in the center of defense was evident from the restart.
Nicolo Barella made it 3-0 six minutes into the second half with a sumptuous 30-meter volley and Dumfries rose above everyone to head home the fourth two minutes later.
Carlos Augusto showed some nice footwork in the box to make it 5-0 in the 77th minute and Marcus Thuram got his 11th goal of the season in the final minute to heap on the misery for the home side.
The result meant Inter were alone in third place, three points behind leaders Atalanta and one behind Napoli with a game in hand.
