The visitors went ahead somewhat against the run of play when Fagioli's cleared cross and subsequent rebound fell kindly for him to finish. Como, fresh from a Coppa Italia win over Napoli, pressed forward but fell further behind when Kean converted a penalty after Maxi Perrone's challenge.
The Lariani's hopes were further dashed when a late corner skimmed both a player's head and the post, leaving Fiorentina with their first away win in Serie A this year.
