Thompson on the march

Nicholas Thompson was the big mover in the early stages of round three at the rain-delayed RBC Heritage.

The American was four under after eight holes of his third round to move him to six under for the tournament and a share of the lead with South Korea's KJ Choi.

But former world number one Luke Donald, former US Open champion Jim Furyk and in-form Matt Kuchar were just a shot further back on a congested leaderboard.

Choi had picked up a single shot through five holes after being one of the players who managed to complete their second round on Friday before play was stopped due to heavy rain.

Furyk had joined him atop the leaderboard when he completed a second-round 66 in the morning and was level par after five holes of his third round.

Donald was making an early move with an eagle at the par-five third, but he gave a shot back on four before picking another up on five to sit one behind the leaders while first-round leader Kuchar was two under after seven.

Reigning champion Graeme McDowell was another early mover as birdies on the opening two holes moved him to four under for the tournament, but bogeys on six and eight saw him reach the turn in level par for his round.

English amateur Matt Fitzpatrick was also two under for the tournament after birdies at five and 10 ensured he was going well through 14 holes.
