BETHESDA, Md. – How good is Rory McIlroy playing? Well, he is three pars away from becoming the first player since 1992 to play the first two rounds of the U.S. Open without making a bogey.

Not to mention, he currently has an eight-shot lead over Y.E. Yang, who doesn’t tee off until 1:35 p.m. The largest previous lead after 36 holes? Tiger Woods’ six-stroke edge in his record-setting, 15-shot victory at Pebble Beach in 2000.

Since 1992, only three players have played the first two rounds and made just one bogey – Ricky Barnes (2009), Phil Mickelson (2004) and Stephen Leaney (2003).
