Ireland Under-20 international Darren Sweetnam got in for Dolphin's and the game's only try, but there was still plenty of action.
The game was streamed live on IrishRugby.ie with over 5,000 hits on the night.
Dolphin's John Quill, who has returned to action following serious surgery, was delighted to receive a call up to the USA squad following his performance.
Quill, who was in the squad during the summer, missed out due to illness. His performance on Friday night was watched by the USA coaching team who then called him up to their squad for their upcoming game against Georgia.
