World number 46 Kodaira was coming off his best major showing, and what had been his top United States result, with a share of 28th at last week's Masters. List's three bogeys on his final six holes ultimately cost him a chance at notching his first tour victory.
Kodaira, 28, had finished off his round of 66 to get to 12-under par about an hour before Kim finished.

After each player parred the 18th hole twice to start the playoff, it was Kodaira who drained a 24-foot birdie putt at the par-three 17th at Harbour Town on Hilton Head Island to secure the biggest win of his career. He made the cut and finished 54th at the WGC-Mexico Championship in March and tied for 28th at the Masters earlier this month-his best finish at a major tournament.
Kim blasted out of greenside bunkers to within five feet to birdie the par-5 second and fifth holes, then holed out from 22 feet at the ninth to make the turn on 15 under. "I wish some of those putts would have dropped".
Kodaira was the hardest charged and few even realized until the final threesome of Kim, Poulter and List all came back to the pack.

Russia, which has also provided critical military support to the Assad regime, has called for an emergency U.N. Turkey is a vocal critic of Assad's regime in Damascus and backed rebels fighting for his ouster.
Sunday's win could represent Kodaira's breakthrough on the Tour as he looks to become more of a mainstay on the final day.
DeChambeau, who held the halfway lead but imploded in the third round to sit seven shots back, mixed two bogeys with seven birdies, including one at each of the final four holes. His roller coaster of a tournament played out again in the final round as he rose three shots to 9-under, then fell back to 7-under before closing with consecutive birdies on the 15th, 16th, 17th and 18th holes.
World No. 1 Dustin Johnson (72) was in a distant share of 41st place and 10 shots behind Poulter after mixing four bogeys with three birdies. He said he plans to work things out over the break and "will be ready for the Players". The weather, while overcast and windy at times, remained calm enough to get in the final round without disruption.
