Lazio left a controversial week behind by winning at relegated Livorno today to secure their Serie A status for next season.
Cristiano Lucarelli's 33rd-minute goal cancelled out Lazio captain Tommaso Rocchi's opener.
Christian Brocchi then scored on the stroke of half-time and the Romans held on for a vital win.
The result lifted the Biancoceleste into 15th place - eight points clear of the drop zone heading into the final week of Serie A.
Livorno went into the game looking to play the role of spoiler and they made their opponents sweat.
Lazio's players had expressed their disbelief after last weekend's setback against Inter Milan at the Stadio Olimpico when the home fans cheered for Inter.
That victory ensured Inter remained on top of the standings ahead of Lazio's bitter rivals Roma, the only side with a chance of beating Jose Mourinho's Nerazzurri to the Scudetto.
Lazio started strongly today with Sergio Floccari the first to threaten with a left-footed strike from 25 yards.
It did not take long for the visitors to go in front as Lazio put a great move together and were rewarded.
Stefano Mauri served Aleksandar Kolarov, whose pass then found Rocchi for an easy tap-in.
Livorno had their first chance in the 15th minute.
Jurgen Prutsch fed Claudio Bellucci at the edge of the area, only for his right-footed strike to go wide.
On the half-hour mark, Giuseppe Biava fired over the bar from 20 yards.
Livorno equalised soon after.
Cristian Raimondi's cross from the far post found Lucarelli and his left-footed strike from five yards beat Lazio goalkeeper Fernando Muslera.
In the 35th minute, Lazio were unlucky not to go in front as Rocchi's attempt from the right side of the area struck the far post.
Lazio continued to press forward and Kolarov forced Livorno goalkeeper Alfonso de Lucia to make a fine save of his stinging drive from outside the area.
Right before half-time, Lazio's efforts paid off.
Brocchi's bullet strike from the edge of the area towards the left corner beat De Lucia.
Lazio picked up where they left off after the restart and Stefan Radu forced De Lucia to fully stretch to clear.
On the hour mark, Martin Bergvold had a chance to level but his left-footed shot from 30 yards went high and wide.
The Amaranto continued to test Lazio's defence.
In the 64th minute, Luigi Vitale's cross found Cristian Raimondi and he fired wide.
Shortly after, Livorno's Davide Moro came closest with his strike from the edge of the area that whistled past the woodwork.
Lazio were forced to defend in the final stages and visiting goalkeeper Fernando Muslera did well to parry away Claudio Bellucci's strike from the heart of the area.
Lazio held on for a deserved win as Livorno played their last Serie A game at the Stadio Armando Picchi for the foreseeable future.
The Biancoceleste can now return home for their last game at home to Udinese.
They will surely receive a warmer welcome this time after protecting their top-flight status.
