Not even the weather, it seems, can interfere with Inbee Park these days.

Thanks to a thick layer of fog blanketing Sebonack Golf Club early Friday evening, second-round play at the 68th US Women’s Open was suspended, the horn going off at 6:40 p.m. Players had the option of finishing the hole they were on or stopping immediately.

Park was on the 18th hole, and chose to continue. She knocked her approach shot to 10 feet, then ran in the birdie putt, ending her round and giving the leader board a very familiar look: Park holding the outright lead.

Her sixth birdie of the day capped a 4-under-par 68, good for a 36-hole total of 9 under. Full story for BostonGlobe.com subscribers.
