Si Woo Kim thinks he's playing like he did four years ago, when he took his first PGA Tour victory at the Wyndham Championship in Greensboro, N.C.
Those chasing Kim in Sunday's final round have to hope he's wrong.
Kim had a hole-in-one on the way to a 62 and a two-shot lead over Doc Redman and Rob Oppenheim after three rounds of the PGA Tour's final event before the playoffs.
Kim got going with his ace on the 161-yard third hole, and thereafter he relived 2016, when every drive hit the fairway.
"I feel like pretty similar this year," Kim said.
There's a difference that could make Kim even harder to beat, he believes: He won the 2017 Players Championship since.
"That's the good experience for me," he said.
Kim, 18 under after 54 holes, has broken 70 in nine of his past 10 rounds.
