Associated Press Luke Donald shot a 66 to take a 2-stroke lead over John Huh on Saturday after three rounds of the RBC Heritage at Hilton Head Island, S.C. Donald has done just about everything on Harbour Town Golf Links the past five years — except win. He lost in a playoff to Brandt Snedeker here in 2011, part of a run of four top-three finishes since 2009. Donald had an eagle and six birdies to finish at 8-under 205 and carry the lead into today here for the second time in that stretch. Huh shot a 68 and was at 6 under. Major champions Charl Schwartzel (68) and Jim Furyk (71), Nicholas Thompson (68) and Ben Martin (71) were tied for third at 5 under. Matt Kuchar, ranked sixth in the world, shot 70 as part of a group of five golfers another shot back at 4 under. Donald’s performance capped a long day at soggy Harbour Town, where 65 golfers had to finish the second round before the third could begin with K.J. Choi, Furyk and Ben Martin tied for the lead. Thompson got things going with five birdies on the front nine to lead at 7 under. But bogeys at the 16th and 18th holes dropped him back into the group at 208. Schwartzel, the 2011 Masters champion, was among those with an early start and jumped into the chase with a third-round 68 to move to 5 under. He said the course held up well despite more than 2½ inches of rain that fell Friday. Furyk, the 2010 winner at Harbour Town, made birdie on his second hole to take the lead at 6 under. He failed to build on that hot start but held on to stay in the hunt.
