Cacoethes is the urge to do something inadvisable. It is pronounced ka-kuh-WEE-theez and is the sort of word that might sound like a curse, an insult, or a sneeze. In other words, it’s a fun tool to have in the box.

Cacoethes is commonplace on the professional golf tours. Pro golfers are trained to believe in themselves, to trust their instinct, above all else. Even when they snatch a coveted caddie, as Collin Morikawa did with Joe Greiner, they still hear their own voice over others, and cacoethes rises.

This week, well, it depends on where you were. We had a bit here, and very little there. We’ll break down this week’s dose of cacoethes for you in Tour Rundown.

PGA Tour @ CJ Cup Byron Nelson: Scheffler is back!

What do you say about Scottie? The 2024 version was unstoppable, tallying wins nearly everywhere, despite the misfortune of fate in Louisville. One might say that the unfortunate encounter with the police department derailed the greatest season of all time. Scheffler was four wins in, plus one major, when his PGA Championship dreams were dashed. That’s a story for another time.

This year, the Scottie and Ted Show nearly repeated at Augusta, but it was Rory’s year. Scheffler looks as comfortable as ever, with Ted Scott as his caddie. His swing is dialed-in, repetitive, and the week always depends on the flat stick. After an opening 61, with an act-two tally of 63, the world once more dropped its jaw in astonishment at his brilliance. The Craig Ranch TPC was no match for the Garden-State-Turned-Texas lad. Scheffler piled on 66-63 over the weekend, posted 31-under 253, and had golf purists longing for the unpredictable nature of the days at Trinity Forest.

If you give these pros a predictable course, they will decimate it.  Scheffler, your honor, is Exhibit A this week from McKinney, Texas. That 10-gallon hat that he received as winner is testimony to his complete subjugation of the Tom Weiskopf golf course.

LPGA @ Black Desert Championship: Ryemarkable Ryu runs away in Utah

There were no identifiable moments of inadvisable decision-making this week in the 45th state. Haeran Ryu took the lead on day one with an enviable 63, kept the spedometer below 70 the entire week, then closed with a 64 to put the competition fully behind. It was one of those “you’ll need 60 to beat me” moments, and there was no one up to the challenge.

Ryu was ryemarkable this week in Ivins. She tallied 24 birdies and 3 eagles over four days, sprinkling in four bogeys to remind us that she wasn’t entirely flawless. The only golfer within five shots of her by tournament’s end, was Germany’s Esther Henseleit. EH burst into our attention span with a silver medal last summer at the Olympic Games. She won the Magical Kenya Open twice on the Ladies European Tour before transitioning full-time to the USA. Henseleit and Ruoning Yin finished tied for second, five shots back of the leader.

Korn Ferry Tour @ Tulum Championship: Nimmer wins North American playoff

Bryson Nimmer (USA) defeated Stuart Macdonald (Canada) in Mexico. That’s as North American as you can get, right? Two trips up the 18th were required in overtime to resolve matters with Nimmer’s two pars just a bit better than Macdonald’s par-bogey. Both players made birdie at the final hole in regulation, to finish two shots clear of the trio in third place.

Davis Chatfield had stitched three 69s together through 54 holes, and a 71 would have done the job on Sunday. Unfortunately for him, the cacoethes came on the 10th hole. Chatfield posted nine consecutive pars on the front nine, but lost focus or patience at the tenth. His triple-bogey seven sent him down the wrong fairway, and he ultimately finished in a tie for 10th, five shots behind the lead.

“Feels good to win.”

PGA Tour Americas @ Peru Open: Wolcott wins in Lima

More cacoethes (cacoetes in Spanish) in the modern capital of the Incas. David Perkins came to the 17th tee at Los Inkas golf club at minus-20 on the week, but signed two holes later for minus-17. Playing partner Hunter Wolcott reached the penultimate hole at 16-deep, but found one last birdie at hole 72. Stunningly, that birdie at the last was enough to win outright in regulation by two shots. JM Butler and Brett White shot the rounds of the day, with 64 and 65, respectively. Neither was able to threaten the leaders, but each reached a tie for third with Taylor Funk.

PGA Tour Champions @ Insperity Invitational: Cink sinks to win

Retief Goosen and Mike Weir entered the final round in the Woodlands as co-leaders. While Goosen was able to fashion a 70, Weir lost his way with 75, tumbling all the way to a tie for 11th place. Goosen had birdies at 14 and 15 coming down the stretch, but was unable to craft one more over the last three holes. This mattered because Stewart Cink was on a run of his own.

Cink sandwiched his solitary, day-three bogey at 14, with birdies at 13 and 15. He made a final birdie at 17, and joined Goosen in a playoff for the trophy. The extra session was swift, as Cink made birdie at the 18th 18th to dispatch the South African champion.

PGA Professional Championship: Collett cruises

There was a time when the PGA Professional Championship took place in the fall, and the qualifiers had to wait nearly nine months to compete in the PGA Championship. Cooler heads prevailed and, when the PGA Championship moved to May, the PGAPC moved to late April.

This year’s event, at one of the PGA’s home resorts, saw a South Florida section professional run away with the title. Tyler Collett from Vero Beach posted 272 to win by 10 shots over Jesse Droemer of Houston and the Southern Texas section. Tied for third was Michael Block of California, the wunderkind from the 2023 PGA Championship at Oak Hill. In all, 23 players finished tied for 20th or better, which meant that four golfers would go to a playoff for the final Club Professional team spot. Michael Kartrude prevailed against Brad Lardon, to join 19 others in qualifying for next week’s PGA Championship at Charlotte’s Quail Hollow Club.
