Finau's place was announced after he finished in a tie for eighth at the BMW Championship in Philadelphia.
"He has an unbelievable body of work this year", Furyk confirmed in a statement after the finish of the rain-delayed BMW Championship. He checked a lot of boxes and made it impossible not to pick him.
Finau, who won his only US PGA title at the 2016 Puerto Rico Open, had three top-10 major finishes this season - sharing 10th at the Masters, taking fifth at the US Open and sharing ninth at the British Open.
Finau, is only the third rookie in Jim Furyk's ranks as the United States try to win on foreign soil for the first time in 25 years.
The Salt Lake City native, now ranked 15th in the world, has one PGA title to his name with the 2016 Puerto Rico Open.
"There won't be any locker room noise with me", Finau said Monday.
Finau had been expected to get the 12th and final spot on the Ryder Cup team based on his overall play, particularly of late. I'm excited to add him to the team.
Furyk did not pull any surprises when he chose Finau to round out his 12-man team for the September 28-30 event against Europe in Paris.
He came in eighth at the BMW Championship, whilst Xander Schauffele came in tied third, so Xander must be really sore at not getting the final pick.
The Ryder Cup is now only a few weeks away from teeing off in Paris but the teams are still yet to be set.
