Key hole in the US Open third round

SAN FRANCISCO – A glance at the key hole Saturday at the U.S. Open:

HOLE: No. 6

YARDAGE: 499

PAR: 4

STROKE AVERAGE: 4.5

RANK: 1

KEY FACT: No hole separated the leaders from the pack more than No. 6. All of the top seven players on the board made par there, even though it yielded the second-fewest pars — 33 — and only because so many players made birdie at the pushover par-5 17th.
