Los Angeles - Sixth-ranked Jordan Spieth completed a three-under par 68 on Friday to move one off the lead after the storm-interrupted opening round of the PGA Tour Pebble Beach National Pro-Am.
Heavy rains and high winds on Thursday rendered all three courses used for the event - Pebble Beach Golf Links, Spyglass Hill and Monterey Peninsula - unplayable even as 81 players had yet to complete their first round.
That forced a Friday morning finish upon them, including Spieth, who parred his final two holes at Monterey Peninsula.
That left him one back of South Korea's Noh Seung-Yul and Americans Joel Dahmen and Rick Lamb, who all reached the clubhouse Thursday on four-under par.
Noh - seeking a second PGA crown following his 2014 New Orleans triumph - had Thursday's only bogey-free round with a 68 at Spyglass Hill, where Lamb and Dahmen also played.
Australia's world number one Jason Day fired a 69 on Thursday at Monterey Peninsula with four birdies and two bogeys, leaving him two back of the leaders as the second round began.
World number four Dustin Johnson, the reigning US Open champion, opened with a 70 at Monterey Peninsula to stand three back, as did fellow American and five-time major winner Phil Mickelson.
