"No one was catching Kaymer this week," Compton said, who earned a trip to the Masters next April. "I was playing for second. I think we all were playing for second."
This US Open really ended on Friday UST.
Kaymer set the US Open record with back-to-back rounds of 65 to set the pace at 10-under 130. After a 10-foot par save on the second hole, Kaymer belted a driver on the 313-yard third hole. The ball landed on the front of the green and rolled to the back, setting up a two-putt birdie.
And he was on his way.
Fowler, in the final group of a major for the first time, fell back quickly with a double bogey on the fourth hole. Compton birdied the eighth hole and got within four shots until he took bogey on the par-3 ninth, and Kaymer followed in the last group with an 8-iron to 4 feet for birdie.
Kaymer finished at 9-under 271.
He won his second major - the other was the 2010 PGA Championship at Whistling Straits in a three-man playoff - and this one wasn't close.
"Martin was playing his own tournament," Fowler said.
Kaymer joined Seve Ballesteros, Ernie Els, Woods and McIlroy as the only players to win two majors and be No. 1 in the world before turning 30 since the world ranking began in 1986. He is the fourth European in the last five years to win the US Open, after Europeans had gone 40 years without this title.
It's a rebirth for Kaymer, who only last month captured The Players Championship.
Kaymer reached No. 1 in the world in February 2011, only to believe that he needed a more rounded game. His preferred shot was a fade. Kaymer spent two hard years, a lot of lonely hours on the range in Germany and his home in Scottsdale, Arizona.
The big payoff came at Pinehurst No. 2.
Kaymer has as many majors as Bernhard Langer, the two-time Masters champion and a mentor to Kaymer. Langer sent him text messages earlier in the week.
"We've almost a German Grand Slam - almost," Kaymer said. "I hope it will make Bernhard proud. I'm sure it will make all of Germany proud."
The biggest challenge for Kaymer was tuning out the crowd, with enormous support for Fowler, who enjoys pop star qualities in America. The fans clapped when Kaymer's ball bounded off the back of the green, and even when a superb shot from the native weeks on No. 4 rolled off the front of the green.
He marched along, dropping a shot on No. 7 with a shot left of the green that made him play away from a bunker to avoid a score worse than bogey, and another on the par-5 10th when a shot from the sandy area sailed over the green, and he used putter to send the next shot back toward the fairway.
But after back-to-back birdies, including a 30-footer on the 14th, the only question left was the margin.
Woods still holds the most dominant US Open win - 15 shots at Pebble Beach in 2000. McIlroy won by eight shots on rain-softened Congressional in 2011, winning with a record score of 16-under 268.
"I'm wondering how he did it," McIlroy said. "Obviously, if you limit the mistakes, you might end up a couple under for the week. But to do what he's doing ... I think it's nearly more impressive than what I did at Congressional."
Kaymer's father was home in Germany, where he said Father's Day was celebrated a few weeks ago.
"I didn't get anything for my father that day," Kaymer said. "So maybe this will work."
