Phil Mickelson will sleep on a three-shot lead at the Pebble Beach Pro-Am after final-round play was suspended due to darkness.
Sunday's fourth round was pushed back an hour due to rain before a hail storm forced play to be delayed for slightly over two hours.
Mickelson entered Round 4 three shots behind Paul Casey but is 6-under through 16 holes and has moved ahead of the Englishman, who stands at even par for the day. Casey will have a three-foot par putt remaining on No. 16 when play resumes.
Playing well and wanting to push through the darkness to finish the tournament, Mickelson was not impressed when the horns sounded to stop play:
Lefty is at 18-under for the tournament with Casey and Scott Stallings - who is in the clubhouse - at 15-under.
The final round will resume Monday at 11:00 a.m. ET.
