Mike Weir couldn't build on his terrific start before darkness forced an end to the second round of the U.S. Open on Friday evening in Farmingdale, N.Y.
The Bright's Grove, Ont., native sits two shots behind American Lucas Glover, who leads the tournament at 6 under par through 13 holes of the second round at Bethpage Black.
Play was suspended at 8:24 p.m. ET. The golfers were also forced to complete the first round Friday as most of Thursday's scheduled action was washed away due to heavy rain.
Ricky Barnes of the U.S. is one shot back through nine holes.
Weir, the leader after the opening round, fell back two shots when he bogeyed holes five and nine, with the latter hole ending his day.
Weir stands in a third-place tie with Sweden's Peter Hanson at 4 under.
Nick Taylor of Abbotsford, B.C., is 2 under through 14, surprising the field with a 5-under second round.
Calgary's Stephen Ames is at even par through nine.
Tiger Woods trailing
Phil Mickelson is 1 under for the tourney through 11 holes, while Tiger Woods finished his opening round with a 74. Woods will begin the second round Saturday morning.
Earlier in the day, Weir shot a career-best 64 to lead the field at 6 under. He finished the first round one shot off the best round in U.S. Open history.
Weir, who started the first round on the back nine, nearly matched the record but missed the green on the par-4 16th hole and three-putted for a double bogey.
Despite his only error of the day, Weir was at 4-under and still tied for the lead. He followed that up with a pair of birdies on his last two holes to finish the day at 6-under, two strokes ahead of anyone else in the field.
"It's about as easy as this course will ever play," Weir said between rounds. "Our side definitely had a big advantage. For us to be able to play in nice conditions all day like this is huge."
Weir came within one stroke of matching the best round ever in any of golf's major championships.
There have been four 63s in the 108 U.S. Opens, the last by Vijay Singh in the second round at Olympia Fields in 2003. Jack Nicklaus and Tom Weiskopf both shot 63 in the opening round at Baltusrol in 1980.
Those three rounds, like Weir's, were shot on courses that played to a par of 70.
The best round in relation to par was Johnny Miller's 8-under 63 in the final round at Oakmont in 1973, which gave him a one-shot victory over John Schlee.
There have been 10 scores of 63 in the PGA Championship, seven in the British Open and two in the Masters.
