MILAN (AP) — Teenage forward Domenico Berardi scored his third hat trick of the season to help Sassuolo win 4-3 at high-flying Fiorentina on Tuesday and boost its hopes of Serie A survival.
The 19-year-old Berardi scored all his goals in the first half to help lift his club out of the bottom three.
"It was a positive attitude but we're not yet safe," Sassuolo coach Eusebio Di Francesco said. "We have two fundamental games left and we can't give up."
"Berardi is a young player who still makes some naive mistakes of a 19-year-old. He has a strong character and the right personality to do what he does in big games."
The teenager also netted three times against Sampdoria and scored four against AC Milan in what proved to be Massimiliano Allegri's final match in charge.
Italy forward Giuseppe Rossi made his first league appearance since January 5 and marked his return from injury with a goal which almost inspired Fiorentina to an astonishing comeback.
The New Jersey-born forward will have boosted his chances of making Italy's World Cup squad.
"Apart from the final result, it was a good match on our part," Fiorentina coach Vincenzo Montella said. "We should be proud of our reaction on the second half.
"Everyone hopes Rossi will be at the World Cup, especially him and he is improving physically. But obviously the choice doesn't depend on me."
Fiorentina remained fourth while Sassuolo moved two points and two places above the drop zone.
Napoli comfortably beat 10-man Cagliari 3-0 in the late match.
Fiorentina goalkeeper Antonio Rosati was making his Serie A debut and he pulled off a couple of decent saves before Sassuolo opened the scoring with a 23rd-minute penalty following a handball by Borja Valero.
Berardi doubled his tally nine minutes later, collecting Nicola Sansone's threaded pass before firing in at the near post. Rosati got a hand to the ball but couldn't prevent it from squirming through.
