BETHESDA, Md. -- When Rory McIlroy holed that pitching wedge for eagle at the eighth hole on Friday, he became the first player to ever hit double digits under par in the second round of the U.S. Open.

Prior to Friday, only four other players had hit double digits at the championship where par is valued above all others. Here are the others:

The 36-hole record in relation to par at the U.S. Open is 8 under and held by Woods and Barnes. Woods shot 8 under on the par-71 Pebble Beach layout in 2000 while Barnes reached the same number on the par-70 Bethpage Black course in 2009.

Looks like McIlroy will shatter that mark, too, doesn’t it?
