After a round of 67 (−5) he finished the tournament at 20-under-par, breaking the previous major scoring record set by Tiger Woods at the 2000 Open Championship.

Branden Grace and Justin Rose also got to within two shots of the lead but fell from contention after double bogeys at the 10th and 13th, respectively.
