BETHESDA, Md. – Rory McIlroy continues to lap the field at the 111th U.S. Open.

The 22-year-old has just made consecutive birdies to become the first player to reach 13 under  at a U.S. Open. And if McIlroy can make a third straight at the 18th hole, he would tie the major championship record of 63 for the second time in his career.

McIlroy two-putted from 15 feet at the par-5 16th hole for the first of his two birdies. The second came courtesy of a 20-footer at No. 17.

Only two players have ever shot two 63s in a major championship – Vijay Singh at the 1993 PGA and 2003 U.S. Open and Greg Norman at the 1986 British Open and 1996 Masters.

McIlory fired a 63 in the first round of last year’s British Open. He has now held at least a share of the lead in five of the last six rounds at a major.
