Dustin Johnson, Fiancee Paulina Gretzky and Son Tatum Celebrate 2016 US Open Win

With a one-under in his final round Sunday, Dustin Johnson won the 2016 U.S. Open at Oakmont Country Club in Pennsylvania to clinch the first major victory of his career with an overall score of four-under. 

After sinking his birdie putt on No. 18 to wrap things up, Johnson had an opportunity to share the special moment with his fiancee, Paulina Gretzky, the daughter of NHL legend Wayne Gretzky, and their son, Tatum. 

Aggrego's Matthew Schwerha shared an image of the whole family together:

It was fitting that Johnson was able to celebrate his first major with his son on Father's Day, as the PGA Tour pointed out:

He told the media after his victory that this Father's Day is at the top of his list, per the PGA Tour:

The moment melted the heart of CBS Sports' Jamie Erdahl:

Johnson will also bring home a big paycheck for his family, winning $1.8 million for his performance at Oakmont. According to ESPN.com's Darren Rovell, he's done pretty well in his career:

There was plenty of controversy, though, as Johnson received a one-stroke penalty because his ball moved while he was setting up to putt on No. 5. The problem was that the USGA did not make the decision to penalize Johnson until after the round was over. 

That won't matter much now for the winner, who can get his celebrations underway with his loving family.
