Connacht needed a late Tietie Tuimauga try to beat Benetton in Italy and keep alive their hopes of reaching the United Rugby Championship play-offs.

Benetton fought back to lead in the second half though with Edoardo Padovani and Toa Halafihi crossing.

But replacement Tuimauga scored with five minutes left to give Connacht their second away win of the season.

The result keeps Connacht in the race for a place in the play-offs as they move up to ninth, five points adrift of the Bulls in eighth.

Looking to bounce back from heavy defeats by Edinburgh and Leinster, Connacht got off to a flier when flanker Prendergast crossed inside the opening minute, collecting a Jack Carty pass before charging home from 40 metres out.

While the hosts got on the board with a Giacomo Da Re penalty, Connacht dominated the majority of the first half and crossed for the second time through Murray, who forced his way over after Paul Boyle had been stopped short.

Carty's conversion put the Irish province 14-3 up at half-time, although coach Andy Friend would perhaps have been disappointed that his side were unable to turn their dominance into further scores.

Ireland wing Mack Hansen made a superb try-saving interception within two minutes of the restart but Benetton got their opening try when Padovani crossed six minutes later to swing momentum in the hosts' favour.

With the game on a knife edge, Connacht were put under more pressure when Prendergast was shown a yellow card just after the hour and they failed to hang on as Halafihi's converted score with 10 minutes left put Benetton ahead for the first time at 17-14.

But having been under sustained pressure, Connacht showed impressive resilience to work their way up the pitch immediately and restore their lead thanks as Tuimauga dived low over the line for his first try for the club.

Benetton applied pressure in the closing stages but their attempts to snatch a match-winning try were repelled by a desperate Connacht defence as the Irish side claimed a crucial victory before next week's European Champions Cup last-16 game against Leinster.
