SAN FRANCISCO – A glance at the key hole Saturday at the U.S. Open:
HOLE: No. 6
STROKE AVERAGE: 4.5
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.
