The second round of the RBC Heritage was cut short because of rain Friday, with K.J. Choi shooting a 4-under 67 for a one-stroke lead over Robert Allenby.
Allenby was among 65 players left on the course when the storm hit Harbour Town Golf Links. Officials delayed the round shortly before 3 p.m. and then suspended it until Saturday morning after waiting through about 90 minutes of steady, heavy rain.
Choi is at 5-under 137 after two rounds.
Former world No. 1 Luke Donald led a group of five at 3 under. Donald shot 69 and joined Billy Hurley III (69) and first-round tri-leader Scott Langley (73) in the clubhouse two shots behind Choi. Bo Van Pelt and Ben Martin were also at 3 under early in their rounds.
