On 19 June 2011, McIlroy amazed the golfing world in capturing his first major championship victory at the U.S. Open at Congressional in Bethesda, Maryland. McIlroy's level of play was unrivaled throughout the week, and his dominance of play is evidenced by his 8-stroke margin of victory over 2nd-place finisher Jason Day. McIlroy set several records in his victory, most notably, his 72-hole aggregate score of 268 (16-under) was a new U.S. Open record. The 268 aggregate beat the previous record of 272 held by Jack Nicklaus (Baltusrol, 1980), Lee Janzen (Baltusrol, 1993), Tiger Woods (Pebble Beach, 2000), and Jim Furyk (Olympia Fields, 2003). The 16-under in relation to par beat Tiger Woods' 12 under at Pebble Beach Golf Links in 2000. He became the youngest winner since Bobby Jones in 1923. The victory lifted McIlroy's position in the Official World Golf Ranking to a then career high of number four.
