ARDMORE, Pa. -- Luke Donald birdied the 13th hole to grab sole possession of the lead as the first round of the U.S. Open was suspended due to darkness at 8:16 p.m. ET.
The birdie was Donald's third straight and moved him to 4 under, one stroke ahead of Phil Mickelson, who is finished at 67, and reigning Masters champ Adam Scott, who just birdied the 11th hole.
Defending champion Webb Simpson is through eight holes at 2 under, tied with Mathew Goggin and Alister Presnell. Lee Westwood, who has completed 13 holes, heads a big group tied at 1 under.
Rory McIlroy is even through 11 holes while his playing partner Tiger Woods is 2 over and has yet to putt out on the 11th green.
The suspension of play was the third of the day but this time, since it was not a dangerous weather situation, players had the option to finish their holes.The two weather delays totaled four hours and 13 minutes.
None of the players who teed off in the afternoon wave finished their first rounds -- the farthest anyone had gotten was 14 holes and the last group to tee off was through just four. All will return at 7:15 a.m. to finish the round.
