Kim quickly erased the error from his mind - and the scorecard - with birdies on the next three holes to regain his lost shots.
The threat of thunderstorms has seen the final round tee times brought forward, with players now going off split tees from 7am-9am local time (noon-2pm BST) to try and get the tournament finished. Sabbatini said he hurt his back on Sunday while practising for this event.
Usually when a bird is involved on the golf course - whether it be a birdie, eagle, or albatross - it's in a positive context, but that wasn't the case Friday for Kelly Kraft. He received treatment every day since and chose to go as long as he good.
Sabbatini surpassed his previous Harbour Town low of 66 in the 2009 final round when he tied for eighth, his best showing in eight previous appearances.More news: PM Modi presents slippers to tribal woman in Chhattisgarh

A second strokeplay win on the PGA Tour would make him nearly certain to make the Ryder Cup in September and, certainly, Thomas Bjorn would have been happy to see Poulter compile an assured round, featuring seven birdies and no bogeys. He caught fire in mid-round, starting a run of four straight birdies on the 18th hole. He fluffed his fifth shot into a bunker, then missed a 5-foot putt for the dreaded snowman.
"This might be the first time I played so well with a triple bogey", Kim said.
Johnson said the early call will be hard as the winds pick up on what has been an unusually mild layout. He drained a 52 foot putt on the par-three 14th hole for birdie and posted another birdie on 18 when he sank a seven footer. And when you're in that position, sometimes the game feels easy when sometimes it isn't'. "To come from last week where getting on the green doesn't mean much, you still have a lot of work to go".
After sharing 38th last week at Augusta National, DeChambeau opened on 68 and followed with another low-scoring round, making birdies on four of the last six holes.
