Ciro Immobile scored a hat-trick as Lazio hammered Sampdoria 5-1 on Saturday to record an 11th consecutive Serie A win and move within three points of leaders Juventus.
A Felipe Caicedo strike and a double from Serie A's leading scorer Immobile gave the hosts a handsome advantage after just 20 minutes.
Substitute Bastos added a fourth in the second half before Immobile completed his hat-trick with his second penalty of the afternoon, taking his tally of league goals for the season to 23.
Karol Linetty scored a consolation goal for Sampdoria with 20 minutes remaining, but their afternoon worsened four minutes later when defender Julian Chabot was sent off for a last-man challenge.
Lazio have become just the fifth team in Serie A history to put together a winning run of more than 10 games, along with Juventus (four times), Roma (twice), Napoli and Inter Milan.
The result leaves the capital club in third place on 45 points, one behind Inter, who travel to Lecce on Sunday, and three adrift of leaders Juve, who host Parma.
