In a matter of 10 minutes Saturday the leaderboard flipped at the Korn Ferry Tour’s Lake Charles Championship.

On the final hole of the third round, the top two chasers of the $135,000 first-place prize changed spots.

First, Seonghyen Kim sank a 7-foot birdie putt to tie for the lead heading into today’s final round. George Cunningham followed by missing a par putt and falling one back.

“A little bummed out,” Cunningham said. “It happens. Still in a really good spot.”

Cunningham and Kim will be paired today in the final group. The two will tee off at 11:35 a.m. with a host of others chasing.

Kim finished strong on the back nine, shooting a blistering 6-under 29. He birdied the first three and then Nos. 14 and 15 before the finish. He enters the final round at 15-under 198.

“The front nine did not go well,” the South Korean Kim said through an interpreter. “As we made the turn I gained some confidence. I’m satisfied with my round and where I’m at.”

Kim is looking for his first tour victory. The 23-year old does have a second-place finish this year and two top 10s.

“I think the greens are firming up,” Kim said. “I have to keep putting well to have a chance.”

Cunningham was the opposite as he started strong. He birdied every other hole on the front nine and was 5-under for the day at the turn to get to 15-under for the tournament.

However, he bogeyed Nos. 10 and 18 while his birdies on the back side were at 12 and 14 to end up at 14 under.

“It is fun to be in contention,” Cunningham said. “It is why we play.”

It will be the second time this season Cunningham is in the final group on a Sunday.

“I hope to get something to eat and get some rest,” Cunningham said. “See how I handle it.”

Brandon Matthews and Corey Pereira were two shots back of the leader. Trying to become the first two-time winner on the tour this year, Matthews fired the day’s best round.

The winner of the Astara Golf Championship in February, shot an 8-under 63 to get back into contention. That included a birdie on 17 when he chipped in.

“I’ve been pitching it really good this week,” Matthews said. “I hit a little pitching wedge runner and it went right to the center. I’m happy with the spot I’m in.”

LSU product Luis Gagne tied Matthews for Saturday’s best round and his 10 under for the tournament.

As for the course, it has played a little easier with the winds dying down the last two days.

“You have to adjust,” Matthews said. “Some of the holes might play a little easier, but there are still some big scores out there. I had one yesterday.”
