ISCO Championship Round 1: Chan Kim's Career-Best 61 Opens a Four-Shot Lead

Chan Kim showed up in Louisville having made one cut in his last seven starts. By lunchtime Thursday, he was four shots clear of everybody.

Kim shot a bogey-free, 9-under 61 at Hurstbourne Country Club to take the first-round lead at the ISCO Championship, the lowest round of his PGA TOUR career. Callum Shinkwin, Thomas Rosenmueller and Peter Malnati are tied for second at 5-under 65. Five more players sit at 4 under, and another 11 are bunched at 3 under, so the chase pack is crowded. It is just a long way back.

The Wedge That Lit the Fuse

The round turned on the par-4 fourth. From 123 yards, Kim hit a 50-degree wedge that never needed a putter, holing out for eagle and jumping to 2 under in a hurry. From there he went to work, piling up seven birdies between the fifth and the 17th, capped by a 24-footer on the par-3 17th.

"The hole-out on 4 definitely kick-started the morning," Kim said. "I'm really proud of how I played today."

He has reason to be. Kim, 35, was born in South Korea, grew up in Hawaii and played college golf at Arizona State. He has eight wins on the Japan Golf Tour and two more on the Korn Ferry Tour, but this is his 70th PGA TOUR start and he is still looking for the first title. Thursday was the first time he has held or shared the lead after any round on TOUR.

The cold stretch coming in was the strange part of this story. Kim said he had missed six of his last seven cuts, and he framed that as freedom rather than pressure. With a 61 in hand, the weekend is basically secured, which means he can keep swinging aggressively instead of scrambling to play two more rounds.

A New Course, Same Opposite-Field Chaos

This is the first year the ISCO Championship has been played at Hurstbourne, about 11 miles east of downtown Louisville, after the event spent the previous several years at Keene Trace in Nicholasville. The Chick Adams design plays as a par 70 at 7,056 yards, and the TOUR flipped the nines so the tournament does not finish on a par 3.

It is the opposite-field event to the Genesis Scottish Open, co-sanctioned with the DP World Tour, which explains the international flavor at the top of the board. Defending champion Harry Hall is not here; he qualified for The Open and is playing in Scotland this week. Nobody in this field is in The Open, so the stakes are all about what a win does for a career: 300 FedExCup points, a two-year TOUR exemption and a spot in next year's PGA Championship, out of a $4 million purse.

Shinkwin Stays Cool in the Heat

The best round in the second tier belonged to Shinkwin. The Englishman played bogey-free and found his own par-4 hole-out, slamming the door on a 107-yard approach at the 12th for eagle. Shinkwin, 32, has won twice in Europe but never on the PGA TOUR.

"I didn't make any mistakes, which is obviously key," Shinkwin said. "It's very easy to lose concentration in the heat."

That line is going to age well at a summer event in Kentucky. Rosenmueller, the German, matched the 65, giving the DP World Tour contingent two of the three spots in a tie for second.

Malnati Makes a Run From the Bubble

Malnati's 65 might matter most for his calendar. The 2024 Valspar champion came into the week at No. 190 in the FedExCup standings, well outside the number that keeps full status. Thursday he made six birdies, including three straight on Nos. 14, 15 and 16, and gave himself a real platform. Malnati, a two-time TOUR winner, noted again how competitive the TOUR has become.

The Pack Behind Them

At 4-under 66 are Kevin Kisner, Troy Merritt, Steven Fisk, Angel Ayora and Cristobal Del Solar. Kisner and Merritt bring the veteran miles, while Fisk got his 66 out of the final group off the first tee.

The 67 group is a who's who of the field's storylines. Emiliano Grillo, the highest-ranked FedExCup player here, opened 3 under just four days after losing a sudden-death playoff to Brian Campbell at the John Deere Classic. Newly minted pro Gordon Sargent, who has been averaging more than 329 yards off the tee, is there too, along with Beau Hossler, Nick Hardy, Callum Tarren, Paul Peterson, William Mouw, Trevor Cone, Cameron Champ, Vince Whaley and S.H. Kim.

Not everyone carried last week's form. Auburn junior Jackson Koivun, who tied for 11th at the John Deere, opened with a 3-over 73. Kentucky native J.B. Holmes, here on a sponsor exemption, shot 74 and has work to do Friday just to stick around.

Four Shots Is a Cushion, Not a Lock

Kim has done the hard part of an opening round: he has built separation without giving anything back. The question for Friday is whether a player who has struggled to make cuts can keep a scorecard that clean on a course this new to everyone. Four shots is real breathing room on a par 70, but with 19 players within six shots and the heat sitting on Hurstbourne, nobody behind him is packing up.
