The year's third major tournament begins Thursday over the windy 7,440-yard (6,800-meter) Long Island layout, where lightning-fast greens and thick rough add to the challenge."A lot of it just comes down to execution, but I think patience is a large part of it as well," said Scheffler.Much of the focus is upon the American, who could become only the seventh player to complete the career Slam with a victory on Sunday, which is his 30th birthday."Would it be a dream to win the US Open? Of course," Scheffler said. "But at the end of the day, the Grand Slam has never been a motivating factor for me. I always just wanted to be the best version of myself and that got me this far."Golfers from the United Kingdom have won the first two majors of the year, second-ranked Rory McIlroy of Northern Ireland defending his Masters crown in April after completing his career Slam last year and England's Aaron Rai taking last month's PGA Championship.It's a feat not seen in the four-major era since the Masters began in 1934, and another European victory would match the continent's best run of three majors in a year since 2014, when McIlroy won the PGA and British Open after Germany's Martin Kaymer captured the US Open.
