Martin Kaymer of Germany hits his tee shot on the second hole during the third round of the 114th US Open on June 14, 2014 in Pinehurst, North Carolina - by Ross Kinnaird
The 29-year-old from Dusseldorf began the round with a six-stroke lead after a historic 36-hole start on 10-under 130, the lowest in US Open history.
But with tougher pin placements on Saturday, Kaymer made three bogeys in the first six holes against an eagle at the par-5 fifth.
After a bogey at six, Kaymer ended the roller-coaster ride and parred six holes in a row until a bogey at 13 and a five-foot par putt miss for bogey at 15 left him on seven-under.
After a par at 16, Kaymer was four strokes in front of Americans Rickie Fowler and Erik Compton, both in the clubhouse on three-under 207 after three-under 67s, the only sub-par rounds of the day.
