Traverse City, United States โ September 13, 2025 โ Karl Cook (USA) wrote another chapter inย Kalinka vanโt Zorgvlietโs comeback story at Flintfields Horse Park on Saturday with a win in theย $62,500 Mercantile Bank Winning Round CSI 5*-W. The penultimate week of the Traverse City Tournament of Champions also marks the launch of theย Longines FEI Jumping World Cupโข North American League season.
This week marked Kalinka vanโt Zorgvlietโs second international competition in nearly a year and a half. The 15-year-old Belgian-bred mare (Thunder vd Zuuthoeve x Flipper dโElle) owned by Signe Ostby was sidelined with a fractured hip in the spring of 2024, and her future at the top level was in question.ย
โHaving this horse back is amazing. Her injury is rough to come back from, but itโs what you have to do whether they come back all the way or retire,โ said Cook, who piloted the mare in the 2023 FEI Nations Cupโข Final in Barcelona. โWhatโs important is that you ride them where theyโre at and if you get where you want to go, great. If not, thatโs the way it goes.
โShe feels great,โ continued the U.S. Olympic team silver medalist. โSheโs always been such a fighter, and itโs so much fun to ride a horse that loves to do the job. She knows how to do it, and today I went as I felt comfortable. If thereโs one fence that feels not right, I just slow down. Thereโs no reasonโfor what sheโs doneโto push it.โ

Kalinka vanโt Zorgvliet was on her game Saturday, and Cook channeled the mareโs footspeed and cat-like turns to finish Guilherme Jorgeโs (BRA) second round inย 38.86 seconds.
In his third five-star podium finish in as many days, Daniel Bluman (ISR) finished second with Gemma W on a second-round time of 39.69 seconds.
Canadaโs Erynn Ballard (CAN) had birthday luck on her side and celebrated with a third-place finish in 42.93 seconds riding Queen Kinmar Hero.
While the 2026 FEI World Cupโข Final in Fort Worth, TX, is on Cookโs radar, the big goal on his horizon is the FEI World Championships in Aachen next year.ย

โWe started preparing after the games last year; a lot of decisions are years in the making,โ said Cook. โRight now itโs about making that U.S. team without overdoing it with the horses.โ
Cook is no stranger to success in Traverse City after winning the American Gold Cup in 2023. โItโs always great to be here. It felt weird not being here last yearโI love showing here; the arenas are great, all my horses seem to jump great here and itโs a great place to spend time.โ
