Hilton Head Island, SC (SportsNetwork.com) - K.J. Choi shot 4-under 67 on Friday and held the lead when the second round of the Heritage was suspended due to inclement weather.
Choi finished 36 holes at 5-under-par 137 before the worst of the weather moved in.
Robert Allenby was 2-under after five holes and was alone in second place at minus-4.
Scott Langley, who shared the first-round lead with Matt Kuchar and William McGirt, tripped to a 2-over 73 to slip to 3-under-par 139. Langley was joined there by Luke Donald and Billy Hurley III, who both posted 69s in round two.
Bo Van Pelt and Ben Martin also stood at minus-3, but had only played five and four holes respectively.
Former U.S. Open champion Geoff Ogilvy managed a 3-under 68 to end two rounds at 2-under 140. Nicholas Thompson and former Masters winner Charl Schwartzel both posted 1-under 70s to end alongside Ogilvy. Four more players were on the course at minus-2.
Kuchar was 4-over par through six holes to slide to minus-1 overall, while McGirt struggled to a 5-over 76 to end two rounds at even-par 142.
Heavy rain at Harbour Town Golf Links halted played for the day. The round will resume at 8 a.m. ET on Saturday.
"We can't play anymore. It's pretty bad out there right now," PGA Tour Vice President of Rules and Competition Slugger White said. "We have a little drying trend between 4 a.m. and 2 p.m. if all goes well. We probably have about four hours left of golf to finish round two and if we can start tomorrow at 8 a.m. we'll try to turn it around and get the third round in and get back on track Sunday somewhere."
Choi started his round with a 14-foot birdie effort on the second. At the fifth, he made a 5-footer on the fifth to move to 3-under. He poured in a 24- footer for birdie on the eighth, but 3-putted for bogey on No. 9.
Around the turn, Choi chipped in for birdie on the 11th and followed with a short birdie effort on the 13th. He missed a short par putt on the 15th, but atoned for that mistake with a 23-foot birdie effort on the 16th.
That gave Choi the lead at minus-5. He ended there with pars on the last two holes.
"Some of the holes played very long with the wind. You had to be imaginative with your shots," Choi said.
Allenby got off to a fast start with birdies on one and two, both from inside eight feet. He parred the next three holes before play was called for the day.
Kuchar found water off the tee on the par-3 fourth and made double-bogey. He again found water off the sixth tee and again walked off with a double-bogey that dropped him to minus-1.
