Rory McIlroy ran out of par saves and had to settle for a 3-under 67 and a share of the lead Thursday in the BMW Championship.
McIlroy appeared to be on his way to building a big lead at Cherry Hills when he made four birdies in a five-hole stretch around the turn. A pair of bogeys late in his round left him frustrated.
Jordan Spieth made two late birdies for a 67. Gary Woodland joined them at the top.
Cherry Hills is one of the shortest courses of the year and it held up fine.
Only 21 players from the 69-man field were under par when the round was halted because of lightning in the area.
Henrik Stenson was at 2 under playing his final hole.
