Si Woo Kim Still Leads THE CJ CUP, but Scottie Scheffler Turned Sunday Into a Real Problem

Si Woo Kim is still leading THE CJ CUP Byron Nelson.

That is the clean factual part.

The more important part is that this tournament no longer feels like his to manage quietly.

After Saturday’s third round on May 23, 2026, Kim stood at 21-under at TPC Craig Ranch, but the lead that looked fat and comfortable after Friday’s electric 60 got trimmed to two shots. Scottie Scheffler and Wyndham Clark both pushed to 19-under, and now Sunday looks a lot less like a coronation and a lot more like a stress test.

This piece is based on the PGA Tour’s official May 23 round-three coverage and leaderboard updates checked on Sunday morning, May 24, 2026. No pretending I got handed the final-round yardage book and a breakfast taco from the scoring trailer.

Friday Was the Fireworks. Saturday Was the Reality Check.

Kim’s Friday round was the kind of score that changes the whole tone of an event.

He shot 60 in round two, got himself into the sub-60 conversation, and created the kind of five-shot separation that usually lets a leader sleep pretty well. But Saturday reminded everybody that TPC Craig Ranch is not just a birdie buffet for one guy.

Kim followed that up with a 3-under 68, which is not bad in a vacuum. It just was not enough to keep the rest of the board from breathing on his neck.

That is what happens when the two most dangerous names behind you are Scottie Scheffler, the defending champion and hometown hammer, and Wyndham Clark, who is fully capable of turning a low-scoring Sunday into a demolition project.

Scheffler Is the One Who Changes the Whole Feel

Clark matters. Scheffler is the problem.

The PGA Tour’s Saturday story leaned into the obvious point: Kim and Scheffler know each other well, and now they get a final-round pairing with an actual tournament on the line. That is fun for everybody else. It is also the exact opposite of relaxing if you are the guy trying to finish the job.

Scheffler shot 65 on Saturday and did it the way he usually does this when he starts circling:

• no wasted holes
• no panicked energy
• no need to do anything theatrical

He just keeps making the board look smaller.

That is why the two-shot gap feels thin even though two shots is not nothing. When the player behind you is the world No. 1 and the defending winner at the same course, every routine par starts to feel slightly less routine.

Kim Still Has the Best Case. He Just No Longer Has Margin.

This is the part worth saying clearly: Kim is still in the best position.

He is leading. He already proved this week that the course fits his eye. He also has enough shot-making volatility to post something silly again if the putter heats up for four more hours.

But that Friday cushion is gone.

Now the win condition is much harsher:

• he probably needs another low round
• he probably cannot afford a sleepy front nine
• he definitely cannot count on Scheffler backing up on his own

That last part matters most. A lot of final-round chases depend on the guy behind you making life easier with one sloppy stretch. Scheffler does not do that very often.

Jordan Spieth Is Still Lurking, Even if This Feels Like a Two-Man Problem

The board is not literally just Kim and Scheffler, even if that is the cleanest story.

Jordan Spieth is still hanging around after the bogey-free 62 he posted on Friday, May 22, when he tied his personal Tour best with six straight birdies. If you want the detailed version of that week’s broader Dallas noise, we already hit the earlier tournament arc in our Brooks Koepka putter-change story and the longer player-case framing in our Jordan Spieth comeback column.

Spieth still needs help, and so does basically everyone else not in the final pairing. But this course has not exactly been handing out pars like heirlooms, so the Sunday board can still get weird in a hurry.

Why This Sunday Matters Beyond One Regular PGA Tour Stop

The Tour has spent a lot of 2026 feeling open-ended.

We already argued in our half-season PGA Tour opinion piece that the season has lacked one clean owner for long stretches. Scheffler winning his hometown event again would feel like a familiar correction. Kim holding him off would feel like a much more interesting disruption.

And that is why this Sunday works.

It gives the tournament two very different endings:

• the best player in the world reasserts control in front of home fans
• or Kim turns a great week into a signature one by staring down that exact threat

Both are real outcomes. That is a better place than this event seemed to be headed late Friday.

Bottom Line

Si Woo Kim still takes the lead into Sunday, May 24, 2026 at THE CJ CUP Byron Nelson, but the shape of the tournament changed on Saturday.

The gap is down to two shots. Scottie Scheffler is in the final group. Wyndham Clark is right there too.

So yes, Kim still controls it.

He just no longer gets to control it comfortably.
