Brian Davis, who nearly won the 2010 RBC Heritage Presented by Boeing before calling a penalty on himself in a playoff won by Jim Furyk, posted a 6-under-par 65 in Thursday morning's opening round, and it stood up for the overnight lead.
A swarm is close on his heels, though.
Kevin Streelman and Charley Hoffman both shot 5-under-66s on Thursday. Marc Leishman, Jason Day and Johnson Wagner are another stroke back, and a group of 16 at 3-under includes Greenville native Bill Haas, defending champion Carl Pettersson, U.S. Open champ Webb Simpson, 1999 Heritage winner Glen Day and former Players Amateur champion Camilo Villegas.
