Rory McIlroy, the young golf pro that many had annointed as the next superstar of the sport, won his first Major on Sunday at Congressional Country Club.

While other golfers were chasing McIlroy, the Northern Ireland star was chasing history.

He shot a 69 on the fourth round, with an eight-shot win.

The 22-year-old phenom went into the Final Round with an eight-stroke lead on Y.E. Chang. Jason Day eclipsed Chang in the end to come in second place.

McIlroy is the youngest U.S. Open champion since Bobby Jones in 1923.  

McIlroy was one of the favorites going into the tournament, and didn't disappoint the spectators. After a meltdown at the Masters where he blew a four-stroke lead and shot an 80 in the fourth round, McIlroy showed no signs of a collapse this time around.

The facts about this momentous victory are staggering. Only four players have finished under par in all four rounds at the U.S. Open. McIlroy set the record for most strokes under par at 16, and also finished with the lowest 72-hole total at 268.

McIlroy finished with several other records. It was perhaps the most notable victory in golf history.

Before the start of this U.S. Open, no player had even been lower than 12-under par. But McIlroy got to 13 under in the first round, 14 under in the second round, and took that mark another three shots lower at one point in the third round, and three under in the fourth round.

McIlroy only had one three put in the Open.

The victory for McIlory marks the sixth time in a row that the U.S. Open was won by a non-American. Last year, the Champion was a fellow Northern Irishman, Graeme McDowell.

Nothing this kid does ever surprises me, McDowell said. He's the best player I've ever seen. 

It may be safe to say that McIlroy is no longer up-and-coming, but rather a superstar golf pro that has many other Majors to win.
