ROME -- Inter Milan wasted a two-goal lead when a glaring error from Fredy Guarin led to a late equalizer by relegation-threatened Livorno in a 2-2 draw Monday.
Five minutes from time, Guarin's ill-advised pass back to defender Walter Samuel was intercepted by Livorno forward Innocent Emeghara, who then did well to beat goalkeeper Samir Handanovic with a long shot.
Brazil playmaker Hernanes had opened the scoring in the 37th with his first goal for Inter since transferring from Lazio in January and Rodrigo Palacio doubled the lead with his 14th of the season in first-half added time.
Paulinho pulled one back for Livorno in the 54th to start the comeback.
Inter remained fifth, only two points ahead of Parma in the race for the final Europa League berth.
It was the third consecutive match Inter failed to win, although this one had to be particularly painful for Inter's first-year coach Walter Mazzarri, who is from the Livorno area.
Earlier, Udinese beat last-place Catania 1-0 with a header from captain Antonio Di Natale in the 68th.
Udinese's 17-year-old goalkeeper Simone Scuffet had another stellar performance, preserving the clean sheet with several difficult saves.
Udinese moved 13 points clear of the relegation zone, with seven rounds remaining. Catania remained one point behind Sassuolo and dropped five behind Livorno.
