Fox said viewing of the exciting end to the U.S. Open Championship hit 11.2 million viewers, tuning in to see 21-year-old Jordan Spieth win a second consecutive major championship victory as Dustin Johnson agonizingly missed a birdie putt that would have forced an 18-hole playoff.

According to a custom analysis provided by Nielsen, the almost 40 hours of coverage of the 2015 U.S. Open reached a total of 34.9 million viewers, Fox said.

The peak on Sunday came in the 10-10:30 p.m. ET half four when Spieth -- who won The Masters earlier this year -- birdied the 18th hole and runner-up Johnson three putted to finish one shot back. 

Fox said the primetime portion of Sunday’s telecast averaged a 5.3 rating and 8.7 million viewers from 7-10:46 p.m. ET, winning the night among the broadcast networks and giving Fox its most-watched Sunday night in primetime since Jan. 4 (NFC Wild Card Playoffs).

Over four days, Fox broadcast network coverage averaged 4.8 million viewers, up 41% over NBC’s average audience for the U.S. Open in 2014 (3.5 million viewers).
