(AP) -- Louis Oosthuizen's drive drifted deep into the right rough.
He laid up short of the green and stood in awe while measuring up his third shot.
Only 240 yards remained to the longest hole in U.S. Open history, the remodeled par-5, 670-yard 16th at The Olympic Club.
If length weren't enough, the sharp dogleg left feels like a constant U-turn and the fairway narrows right at 300 yards.
The flag is often blind until the third shot, and ones that miss long or left will bounce even farther away because of the grass mowed razor-thin beyond the tiny green.
Tiger Woods can't stop talking about how the U.S. Open presents the toughest test of the year.
Woods is coming off his second win of the year at the Memorial, where he rallied from a four-shot deficit in the final round.
That made him the betting favorite to win his fourth U.S. Open title.
Then again, Woods was coming off a win in his last start before the Masters, and he was never a factor.
He will be playing with Phil Mickelson and Masters champion Bubba Watson when the championship starts Thursday.
