Gonzalo Higuain struck twice as Napoli came from behind to beat Genoa 3-1 at the Stadio San Paolo to keep their Serie A title hopes alive.
The win sees Napoli push to just three points behind leaders Juventus again after a third league win in a row, and it came thanks to Higuain's double and a third goal from Omar El Kaddouri.
Juventus beat Torino 4-1 earlier in the day and Maurizio Sarri's team went into the early-evening game knowing they needed a win to stay in close touch with the front-runners.
Napoli were taken by surprise when Gian Piero Gasperini's visitors opened the scoring after 10 minutes as Tomas Rincon's powerful right-footed shot from outside the box caught goalkeeper Pepe Reina off guard.
And the home team struggled to get into the game in the first half as Genoa did their best to double their advantage, but it was a different story after half-time.
Higuain levelled after 51 minutes when Elseid Hysaj's smart ball forward into the box found him in plenty of space, and he slotted home low.
The forward then put his team in front with his second of the game with just nine minutes remaining, a curling 16-yard strike in off the right post.
El Kaddouri secured the points in injury time by scoring Napoli's third as he slotted home Manolo Gabbiadini's cross.
Genoa slipped to their first defeat in the league since February, while Sarri's Napoli are now unbeaten in their last five Serie A matches.
