<p dir="ltr">Don&rsquo;t let the four-horse field fool you. The combinations lining up for this weekend's Grand Prix Freestyle at the <strong>Ginny Rattner Dressage Memorial CDI3*</strong> are riding for their postseason lives. In a single afternoon, one freestyle ride could lock up a Final qualification, rescue a leaderboard bubble position, or launch a dark-horse CDI debut. With only four qualifiers left on the calendar, there is no room left for a safe ride in Sherwood, Oregon.</p>
<p><iframe id="datawrapper-chart-SbspO" style="width: 0; min-width: 100% !important; border: none;" title="Ginny Rattner Memorial Dressage CDI3*" src="https://datawrapper.dwcdn.net/SbspO/1/" height="476" frameborder="0" scrolling="no" aria-label="Table" data-external="1"></iframe></p>
<h2 dir="ltr">Harrison-Antell and Finley: The Benchmark</h2>
<p dir="ltr"><strong>Kristina Harrison-Antell</strong> and <strong>Finley</strong> are the field's most credentialed combination, boasting ten FEI freestyle starts, a 75.470% personal best, and a 71.76% average that no one else here has matched at this level. In a four-horse class, that record is the metric everyone else is measuring against.</p>
<p dir="ltr">However, their last two outings have not looked like that record. Recent scores of 70.730% and 68.835% both sit below their average, dropping them off the top step of the podium. In a tiny field, an off-day is glaringly exposed. A win this weekend would propel Harrison-Antell from outside the top 18 up to 29 points, thrusting her right back into qualifying range. The history books say she should be the one delivering it; recent form says she has her work cut out for her.</p>
<h2 dir="ltr">Jackson and Florisson: Already Done It Once</h2>
<p dir="ltr">The clearest evidence that a paper record guarantees nothing came six weeks ago at Del Mar, where <strong>Cyndi Jackson </strong>and <strong>Florisson</strong> stole the freestyle win with Harrison-Antell in the field. Jackson wasn't the favorite that day either. She is faced with the same challenge again this weekend, but the Series stakes have grown significantly.</p>
<p dir="ltr">Jackson currently sits at 18 points, just on the edge of assured qualification. A win takes her to 44 points and sixth place, rendering a Final berth a certainty. While three FEI freestyle starts is a thin statistical sample, Florisson posted blistering 78.000% and 76.600% scores as a 6-year-old. What this combination looks like as Florisson matures into peak Grand Prix age, hasn&rsquo;t been fully realized yet. The last time Harrison-Antell opened the door, Jackson stepped through it, and she&rsquo;ll be looking to do it again this weekend.&nbsp;</p>
<h2 dir="ltr">Jorst and Niquel Cap: Arriving with Evidence</h2>
<p dir="ltr"><strong>Charlotte Jorst</strong> walks in with a storied FEI career, but her partner, the 9-year-old Lusitano stallion <strong>Niquel Cap</strong>, has exactly one national Grand Prix Freestyle on his resume. That single performance was a massive 74.500% win at the Starr Vaughn Spring Dressage II last weekend, paired with a 72.065% Grand Prix the day before. That 74.500% is the highest freestyle score any combination in this field has posted recently&mdash;and it came on the horse's very first time down the centerline to music.</p>
<p dir="ltr">A CDI is a different stage than a national show, and a debut is always a wild card. But a partnership that sweeps both tests in its debut outing and logs a score higher than Harrison-Antell has managed in two months, arrives in Sherwood with the kind of momentum that could absolutely topple a favorite. A win would vault Jorst from 47th place (6 points) into the low 20s. That's within Final contention if she can squeeze one more qualifier into her calendar.</p>
<h2 dir="ltr">Winger, Unai, and the Home-Field Legacy</h2>
<p dir="ltr"><strong>Ben Winger</strong> and <strong>Unai</strong> round out the entry list, and they hold the distinct advantage of the shortest commute. Winger has been based at Oregon since fall 2025, following professional stints at GoldMark Farm in Ocala and Paragon Farm in Texas. After Unai stepped up to the Grand Prix level at WEC Ocala in July 2025, the move to Oregon unlocked something special.</p>
<p dir="ltr">Since arriving, the partnership has gone completely undefeated at DevonWood, racking up four Grand Prix wins, alongside two national Grand Prix Freestyle victories just weeks ago (scoring 70.575% and 70.900%). While this weekend marks their official CDI freestyle debut, it is hardly an unfamiliar test. Unai has done all of his freestyles dancing on this exact footing.</p>
<p dir="ltr">Founded in 1998 by Ginny and Justin Rattner on 40 acres in Oregon's Willamette Valley, DevonWood represents the bedrock of the Pacific Northwest dressage community. Though Ginny passed away from breast cancer in July 2013, her children have kept her vision alive, running the facility and expanding its footprint.</p>
<p dir="ltr">The Ginny Rattner Memorial CDI3* joined the Open qualifier circuit in 2025, and this weekend marks its second year as a premier calendar destination. The show honors the woman who built the world-class facility that Winger now calls home. For Winger and Unai, the weekend isn't just an international debut, it's a defense of home turf.</p>

No Safe Rides in Sherwood

The 10 Best Performances of the 2026 US Equestrian Open of Eventing

The Open Weekly: Bicton, Aachen & The Ginny Rattner Memorial

<p data-start="0" data-end="113">For <strong>Isabelle Bosley &amp; Conner, </strong>the rise has been building for a while. Now, it is becoming impossible to ignore.</p>
<p data-start="115" data-end="292">The nine-year-old gelding closed out 2025 with a win at Maryland CCI3*-L, producing the highest-rated performance at the level on US soil all season. That result was no one-off. Across the year, the pair recorded three international wins, one runner-up finish, and clear showjumping rounds at every FEI start - establishing <strong>Conner </strong>as one of the standout young horses in the country.</p>
<p data-start="115" data-end="292"><img src="https://usef-admin.fly.dev/assets/e1d1626d-517c-48be-a305-04a8f5b2c198.png?width=1580&amp;height=1712" alt="Yl6 Oh Top 10 Cci3 L Hprs on Us Soil in 2025 "></p>
<p data-start="500" data-end="765">This spring, they stepped into four-star company, most recently adding a sixth-place finish at Kentucky CCI4*-S to an already impressive resume. Off the back of another major performance, <strong>Conner </strong>now sits fifth among US nine-year-olds on EquiRatings Elo.</p>
<p data-start="767" data-end="851" data-is-last-node="" data-is-only-node="">But the real story behind<strong> Conner &amp; Isabelle </strong>is not just the results, it is how they got there.</p>
<p>&nbsp;</p>
<p><iframe style="border-image: initial; border: medium none currentcolor;" title="Embed Player" src="https://play.libsyn.com/embed/episode/id/41365105/height/192/theme/modern/size/large/thumbnail/yes/custom-color/28427a/time-start/00:00:00/hide-playlist/yes/download/yes/font-color/ffffff" width="100%" height="192" scrolling="no" allowfullscreen="allowfullscreen"></iframe></p>
<h2 data-section-id="15vcrml" data-start="819" data-end="849">&nbsp;</h2>
<h2 data-section-id="15vcrml" data-start="819" data-end="849">Produced From the Beginning</h2>
<p data-start="851" data-end="1008">Having&nbsp;been brought up in a deeply horsey family, Isabelle was immersed in the sport from the beginning. Her parents are both racehorse trainers, and much of her early riding came through foxhunting, galloping racehorses, and spending her childhood around barns. Producing horses herself was never really a question, it was simply the way she learned the sport.</p>
<p data-start="362" data-end="558" data-is-last-node="" data-is-only-node="">And that's how <strong>Conner</strong> entered the picture. Isabelle bought him at the end of his five-year-old season, before he had done much of anything in the sport, and everything since then has been built together.</p>
<blockquote data-start="1010" data-end="1330">
<p data-start="1012" data-end="1185"><em>&ldquo;When I got him, he had not done anything. So we&rsquo;ve had him from the very beginning stages, first cross-country school, first horse show. So it&rsquo;s been a very long process. I know him really well. And he really trusts me."</em></p>

<p data-start="0" data-end="395" data-is-last-node="" data-is-only-node=""><strong>Conner</strong> feels like the first true top-level horse Isabelle has had underneath her.

<p data-start="0" data-end="395" data-is-last-node="" data-is-only-node="">But even now, despite the results and growing attention around the partnership, she still talks about <strong>Conner</strong> like the young horse she first brought home as a five-year-old.</p>

<h2 data-section-id="6tvhvy" data-start="1654" data-end="1677">&nbsp;</h2>
<h2 data-section-id="6tvhvy" data-start="1654" data-end="1677">Maryland to Kentucky</h2>
<p data-start="1679" data-end="1736">Maryland CCI3*-L felt like the moment everything clicked. <strong>Conner's </strong>96 HPR placed him alongside some of the strongest three-star performances seen from young horses in the US over the last number of seasons.</p>
<p data-start="1922" data-end="1955">The next challenge was four-star.</p>
<p data-start="1957" data-end="2177">Stepping up this spring came with a learning curve. Isabelle admits there were moments where the pair had to rethink things, particularly around balance and control as&nbsp;<strong>Conner </strong>adjusted to bigger tracks and faster questions.</p>
<p data-start="2179" data-end="2262">Kentucky, though, looked like confirmation they were moving in the right direction.</p>
<blockquote>
<p><em>"The bigger the crowd, the better it is for me, especially on cross-country. It kind of lifts him up and gets him to take things in instead of just running. So it works in my favor and he loved it. I could feel him going around just like 'Oh my God, all these people are here for me.'"</em></p>
</blockquote>
<p data-start="2543" data-end="2744">While many young horses can shrink in major atmospheres, <strong>Conner </strong>seemed to grow into it. Isabelle described him calmly taking in the atmosphere during the warm-up and feeding off the crowd once out on course.&nbsp;The result was a polished top-10 finish at one of the biggest and most prestigious venues in the sport.</p>
<p data-start="2746" data-end="2828"><img src="https://usef-admin.fly.dev/assets/014e6964-ab34-43b2-b1f0-34fcc253c5c9.jpg?width=4625&amp;height=3316" alt="Iw 26 K3 De CC I4 Jump Isabelle Boseley Conner 3"><em style="font-size: 90%; color: #999999;">Isabelle &amp; Conner show jumping clear with 0.8 time penalties at the Cosequin Lexington CCI4*-S</em></p>
<h2 data-section-id="1e2gfcj" data-start="2835" data-end="2853">&nbsp;</h2>
<h2 data-section-id="1e2gfcj" data-start="2835" data-end="2853">Still Only Nine</h2>
<p data-start="2855" data-end="2947">What stands out most about Isabelle's approach is how patient she remains despite the success. <strong>Conner </strong>is producing elite-level performances already, but she still frames the season as part of a bigger development process rather than a finished product.</p>
<blockquote>
<p data-start="2855" data-end="2947"><em>"I just remind myself he's just a nine-year-old and he's still such a baby. Each event we're just learning something new and I do think every event we've gotten better and better."</em></p>
</blockquote>
<p data-start="3352" data-end="3465">That mindset may be one of the biggest reasons this partnership has progressed so quickly without feeling rushed.</p>
<p data-start="3467" data-end="3604">And while the results already place <strong>Conner </strong>among the most exciting young horses in the country, Isabelle's focus is firmly on the future. The current plan is to head to the US Equestrian Open Final at Morven Park. It is already a meaningful venue for Isabelle, having been the only four-star long she has successfully completed before. This time, though, she returns with a very different kind of horse underneath her.</p>
