Felipe Caicedo and Ciro Immobile were on target to end the positive Fiorentina streak and revitalise Lazio.
Both goals saw players knock the ball on for a volley from close range, with Bartlomiej Dragowski not judging the flight of the cross correctly.
Immobile also had another ruled out for offside, while Dusan Vlahovic set up a tense finale with his penalty.
