Felipe Caicedo’s ferocious shot proved the difference to put Lazio a point off fourth-placed Milan, but Frosinone saw a penalty awarded and then revoked.
There were some changes after being forced to extra time and penalties by Inter in the Coppa Italia quarter-final on Thursday.
Sergej Milinkovic-Savic was suspended with Luiz Felipe and Wallace injured, so Riza Durmisi got his first Serie A start. The hosts missed Federico Dionisi, Paolo Ghiglione, Stefan Simic, Nicolò Brighenti, Lorenzo Ariaudo and suspended Francesco Cassata. They too were brimming with confidence after a 4-0 win away to Bologna, but remained in penultimate place.
Marco Sportiello was alert on Felipe Caicedo and Milan Badelj efforts, but Frosinone went close on 15 minutes when Andrea Pinamonti’s acrobatic volley on the turn flashed wide.
At the other end, Federico Viviani on his Frosinone debut flung himself in the path of a Caicedo strike.
There was controversy on 25 minutes when the referee pointed to the spot for Bastos holding back Camillo Ciano as he was at full stretch trying to reach a Raman Chibsah cross. However, with Ciano standing on the spot waiting to take his penalty, the referee went over for a VAR review and changed his mind, as Bastos did begin to tug the arm, but let go immediately.
Instead, Lazio took the lead when Luis Alberto was allowed to surge through the middle and set up Caicedo, who took one touch before smashing it into the roof of the net with his left foot.
Frosinone were angry that Marco Parolo didn’t receive a second yellow card for a late tackle on 55 minutes. Caicedo should’ve made it 2-0, but ballooned over the rebound when Parolo’s snapshot was parried into his path.
Luis Alberto pulled up with a muscular problem and limped off, whole the Canarini threw on every forward they had in a bid to get this back on track.
It almost worked, because first Pinamonti blasted over when in a promising position, then Marcello Trotta forced Thomas Strakosha to parry with his legs. Lazio clung on under pressure in stoppages for the three points and join Roma in fifth place.
