It's down to the wire now for the five contenders who have been shortlisted for the ultimate individual accolade in northern hemisphere rugby, ERC European Player of the Year 2013.
The Dragons then equalised from their first piece of real pressure in the Italian 22 all game, outside half Ceri Sweeney was obstructed after his own kick ahead and he landed the penalty from in front of the posts.
However Calvisano got the first try of the game just before half-time through left wing Warren Spragg. He was put in a by a long pass from centre James Downey after prop Gabriel Bocca made the initial break up the middle.
The final act of the half was another missed chance for the Italians, replacement outside half Michael Gallinetti missing a 50 yard penalty attempt.
However Calvisano scored a try early in the second half to extend their lead. Lock Valerio Bernabo was too shrugged off the tacklers on a 15 yard run to the line after Gallinetti and Spragg had combined down the short side to make the opening.
De Marigny converted from touch to make it 15-3 to the Italians. The Dragons replaced Wales lock Ian Gough, playing his last game for the region before moving to the Ospreys over the summer.
The Dragons needed a score to have any hope of getting back into the game, but a moment of magic from right wing Gareth Wyatt brought that much-needed try.
He collected his own kick ahead from turnover ball to almost make it to the line on the right and then the ball was spun wide to the left for fellow wing Martin Thomas to cross the line after a long cut out pass from Sweeney.
Sweeney converted from near touch to further inspire his side as they got back within a score.
As the crowd started to strongly get behind their team the Dragons came back with their best period of the match.
They got their reward with a try by lock Luke Charteris as he powered his way through to the line following an extended period of forward pressure in the Italian 22.
That put the scores level on 15-15. Sweeney missed the conversion from touch and then De Marigny missed a penalty shot from similarly wide out.
Then came the decisive moment of the game as the crowd again roused the home team to greater efforts. The forwards piled on the pressure and when the ball went wide Aled Thomas's pass was latched onto by Emerick and he had the power to get over the line.
Sweeney converted as the game went into injury and the Dragons held on comfortably
