In their first competition since last summer&rsquo;s European circuit, Anna Buffini and Fiontini clinched the Grand Prix Freestyle win at the Del Mar Dressage Affaire with a score of 73.235%. A narrow margin separated Buffini from her longtime coach, G&uuml;nter Seidel&mdash;just 0.155%.
<h2 dir="ltr">A Smooth Return for Dressage&rsquo;s Favorite &lsquo;-inis&rsquo;</h2>
It was a quiet class in sunny Southern California, with only four combinations entered in the freestyle. While eight riders completed the Grand Prix this weekend, the field split between Special and Freestyle divisions. This marks Buffini&rsquo;s first appearance in a US Equestrian Open of Dressage qualifier, and her win earns her 20 points&mdash;putting her alongside three other riders tied in the standings. With only two West Coast qualifiers remaining, Buffini could still climb the leaderboard&mdash;but unless she plans to head East for additional shows, her path to the Finals may be limited.
Their final score of 73.235% this weekend marked a steady, if not spectacular, return. Although Fiontini boasts one of the highest personal bests in the field&mdash;an 83.410% earned earlier in her career under a previous rider&mdash;Buffini is still forging her own path with the 15-year-old Danish Warmblood mare.
Buffini acquired Fiontini in late 2021 but kept the mare largely out of the spotlight for the first two years of their partnership, focusing instead on building trust and fine-tuning the basics. It wasn&rsquo;t until February 2024 that the pair made their international debut at the CDI3* in Del Mar, where they finished second in both the Grand Prix and the Grand Prix Special . The mare, a triple World Young Horse Champion, has passed through the hands of some of Europe&rsquo;s most prolific male riders. In Buffini&rsquo;s program, she&rsquo;s found a quieter cadence&mdash;one that prioritizes partnership over pressure.
Sunday&rsquo;s result gives them a strong foundation to build from this season. The test wasn&rsquo;t without its quirks&mdash;most notably, a wide spread in the scoring for their extended canter. One judge awarded an 8, while others gave 5s and even 4s, suggesting a possible miscommunication or moment of misinterpretation. Still, the performance was enough for the win.
<h2 dir="ltr">Seidel Shows His Hand</h2>
G&uuml;nter Seidel and Equirelle posted a 73.080%, a marked improvement from their last US Equestrian Open outing, where they earned a 68.695%. This time, two judges&mdash;at H and C&mdash;actually placed Seidel in first, awarding him 74.200% and 75.175%, respectively. Those were the highest individual scores given in the class.
Their test was clean and cohesive, with no major weak spots. The 16-year-old KWPN mare looked relaxed and rideable, and the pair&rsquo;s degree of difficulty averaged 9.16&mdash;just edging out Buffini&rsquo;s 9.12&mdash;making a strong case that Seidel delivered the more technically ambitious ride of the day.
<h2 dir="ltr">Standings Update</h2>
Canada&rsquo;s Brittney Simpson and her mount Kartsevo Goldfinch placed third on a 72.010%, while Kristina Harrison-Antell and Finley rounded out the field with a 68.140%. The result brings both Simpson and Harrison-Antell to a tie for ninth place in the overall US Equestrian Open of Dressage standings, each sitting on 49 points.

<h2 dir="ltr">What&rsquo;s Next</h2>
While this weekend didn&rsquo;t dramatically shake up the leaderboard, Seidel&rsquo;s upward trajectory is one to watch. With only two more West Coast qualifiers remaining, his path to the Finals may require a few cross-country miles&mdash;but if he wins another qualifier and picks up additional points out East, he could position himself for a return trip to Thermal this fall.
Qualifier 13 takes place this Friday in Wellington, Florida, during the final week of the Adequan Global Dressage Festival. Tune in live to the USEF Network to watch the action unfold.

Buffini Returns, Seidel Surges: A Tight Finish at the Del Mar Affaire 

Main

Only four horses are entered in this week&rsquo;s qualifier, but don&rsquo;t let the numbers fool you. &ldquo;Small field&rdquo; does not equal &ldquo;small story.&rdquo; From a US Equestrian Open of Dressage leaderboard perspective, this show won&rsquo;t be the most consequential event of the season. But it will, however, feature one of the most celebrated horses in the entire Series: Fiontini.
<h2 dir="ltr">A Living Legend</h2>
The 15-year-old Danish Warmblood mare has one of the most consistent records in the sport. In 15 Grand Prix starts, she&rsquo;s dipped below 69% just twice. In the freestyle, she consistently scores in the mid-70s to 80s, no matter the rider. A Triple World Young Horse Champion (2015&ndash;2017), Fiontini isn&rsquo;t just good; she&rsquo;s reliably brilliant.
Over the course of her career, she&rsquo;s been ridden by some of Europe&rsquo;s top male riders: Severo Jurado L&oacute;pez, Andreas Helgstrand, and Patrik Kittel. Now, she&rsquo;s owned and ridden by 30-year-old US team rider Anna Buffini&mdash;one of the youngest athletes to represent the US at a World Championship in recent years. After purchasing the mare, Buffini joked that it was time to turn Fiontini into a &ldquo;lady&rsquo;s ride.&rdquo;
<iframe id="datawrapper-chart-Bh1Wn" style="width: 0; min-width: 100% !important; border: none;" title="Fiontini's Grand Prix Freestyle Scores" src="https://datawrapper.dwcdn.net/Bh1Wn/1/" height="646" frameborder="0" scrolling="no" aria-label="Interactive line chart" data-external="1"></iframe>
<h2 dir="ltr">A New Chapter</h2>
Buffini first saw Fiontini competing with Kittel at Aachen. It only took one test ride for her to fall in love with the mare&rsquo;s big heart and immense talent. But transitioning Fiontini to Buffini&rsquo;s lighter riding style became a project of patience and tact. She was used to stronger leg aids and, at first, would shake her sides like she had flies on them when Buffini applied pressure.
So began the process of teaching her to respond to subtler cues&mdash;a new language for horse and rider. With the help of her longtime coach G&uuml;nter Seidel (also entered in this weekend's class), they opted for a long runway: two full years out of the spotlight, focused on trust, softness, and feel.
Buffini, who has a large social media following, chose to keep Fiontini&rsquo;s training private. Fans were eager to see the mare return to competition, but Buffini stayed steady in her approach.
<blockquote>
&ldquo;When she&rsquo;s ready, we&rsquo;ll come out.&rdquo;
</blockquote>
<h2 dir="ltr">A Measured Return</h2>
That moment came 11 months ago&mdash;at this very venue. They scored 72% in the Grand Prix and 72.447% in the Grand Prix Special, a notoriously difficult test. In both, they placed second to decorated U.S. Olympian Steffen Peters and Suppenkasper. The Special was particularly close: four of the five judges placed Buffini ahead of Peters, who won by a razor-thin 72.766%.
Buffini and Fiontini debuted their freestyle the following month, again in Del Mar, earning a 76.210%. Judges rewarded the mare&rsquo;s expressive, expansive gaits with 8s for extended walk, trot, and canter. Their floor plan earned a 9.16 average degree of difficulty. The question now: in the year since we&rsquo;ve seen them perform this freestyle, have they dialed that difficulty up even further?
<h2 dir="ltr">A Delicate Dance</h2>
<iframe id="datawrapper-chart-xKbdJ" style="width: 0; min-width: 100% !important; border: none;" title="Grand Prix Freestyle Stats:&nbsp;Del Mar Dressage Affaire&nbsp;" src="https://datawrapper.dwcdn.net/xKbdJ/1/" height="459" frameborder="0" scrolling="no" aria-label="Table" data-external="1"></iframe>
With only four riders in Sunday&rsquo;s freestyle class, Buffini and Fiontini are the clear favorites. This is a chance to polish the freestyle, push the degree of difficulty, and test Fiontini&rsquo;s firepower. Seidel is the only one who could realistically challenge her. Equirelle&rsquo;s personal best&mdash;76.615%&mdash;actually edges out Buffini&rsquo;s PB on Fiontini (76.210%), but Seidel&rsquo;s last outing suggests they&rsquo;re still shaking off some freestyle rust.
Still, Seidel is a veteran, and you can never fully count him out.
Under Buffini, Fiontini is no longer just a powerhouse. She&rsquo;s expressive, responsive, and joyful in the ring. &ldquo;She&rsquo;s really become my horse,&rdquo; Buffini said after their debut. This weekend, Del Mar gets to see that magic in action.
For the West Coast, it&rsquo;s a reminder that top sport lives here too&mdash;even with smaller fields. Fiontini&rsquo;s presence brings eyes and gravitas to the Series. And for fans, it&rsquo;s a rare chance to see one of the most celebrated dressage mares of the modern era compete on home turf.
Fiontini might not be &ldquo;on the comeback&rdquo;&mdash;she never really left. But Del Mar might be where we see her new era begin.

Born into an equestrian dynasty, Alex grew up in a house just 100 meters from the barn, with horses as a constant presence. His father, Michael Matz, is a three-time Olympian, World Championship medalist, and Kentucky Derby-winning trainer. His mother, D.D. Matz, is also a Pan American Games medalist with an exceptional eye for talent.
Despite this pedigree, there was no pressure to ride. &ldquo;They never forced me to do it,&rdquo; Alex says. &ldquo;I think the pressure I feel is the pressure I put on myself.&rdquo;
<h3 class="sh-color-black sh-color">Finding His Own Path in Show Jumping</h3>
Unlike many top juniors who compete intensively from a young age, Alex didn&rsquo;t take the sport seriously until after college. While studying, he watched his friends pursue finance careers in New York City, but the corporate world didn&rsquo;t have the same appeal.
<blockquote>
&ldquo;It wasn&rsquo;t as appealing as following my dreams and making a career with horses,&rdquo; he says. 
</blockquote>
After graduation, he fully committed, training with industry greats like John and Beezie Madden and Jos Lansink, learning from their expertise and blending it with the knowledge gained from his parents.
<h3 class="sh-color-black sh-color"><img src="https://usef-admin.fly.dev/assets/6ca3d3ca-493a-4faf-bb7b-96319d36df21.png?width=1080&amp;height=1080" alt="Alex Matz 1"></h3>
<h3 class="sh-color-black sh-color">Toronto Triumph and a Partnership Built on Trust</h3>
One of Alex&rsquo;s biggest career highlights came at the Royal Horse Show in Toronto, where he won three FEI classes&mdash;an achievement he still can&rsquo;t quite believe.
&ldquo;That week was fantastic,&rdquo; he recalls. &ldquo;The crowds are huge, and I don&rsquo;t think I&rsquo;ve ever won three FEI classes at one show before.&rdquo;
One of the horses that took him to victory was Ikigai, a talented gelding owned by the McNeil family, who have been instrumental supporters of Alex&rsquo;s career.
&ldquo;Ikigai had an injury where he was out for close to a year, and they really stayed patient,&rdquo; Alex explains. &ldquo;We had always believed he would win a five-star Grand Prix, and when he did, it was amazing.&rdquo;
With the US Equestrian Open on the horizon, Ikigai is Alex&rsquo;s top contender. &ldquo;He&rsquo;s the most talented horse I&rsquo;ve ever ridden,&rdquo; he says. &ldquo;If I do things right, he&rsquo;ll jump clear.&rdquo;
<h3 class="sh-color-black sh-color">The Hard Work Behind the Success</h3>
A key part of Alex&rsquo;s development has been the daily commitment from his father. Even with a full racing stable to manage, Michael Matz still makes time to train with Alex every day. 
&ldquo;My dad is up at 4:30 AM to go to the racetrack, then comes here, and we have a flat lesson every day,&rdquo; Alex says. &ldquo;Having him and my mom&rsquo;s guidance is the best strategy for me.&rdquo; 
His mother, known for her sharp eye in selecting talent, balances out his father&rsquo;s optimism. &ldquo;My dad thinks every horse can go to the Olympics,&rdquo; Alex laughs. &ldquo;And I like every horse too! But my mom is much more selective.&rdquo;
<img src="https://usef-admin.fly.dev/assets/c9d3598e-d999-483c-8997-0c63072dd74f.png?width=1080&amp;height=1080" alt="Alex Matz 2">
<h3 class="sh-color-black sh-color">Why the US Equestrian Open Matters</h3>
The US Equestrian Open represents something bigger than just another major event. With Rolex and USEF coming together to create a new, elite series, Alex sees it as a game-changer.
<blockquote>
&ldquo;It brings a lot to the sport&mdash;not just for the riders and owners, but also for the fans,&rdquo; he explains. &ldquo;It brings us all together toward a common goal that will be really good for show jumping.&rdquo; 
</blockquote>
Winning the inaugural US Equestrian Open Jumping Final would be a defining moment.
<blockquote>
&ldquo;We know it&rsquo;s going to be the best horses and riders, so it will be extremely competitive,&rdquo; Alex says. &ldquo;But if it all goes right, it would further prove how incredible Ikigai is, and how strong our partnership has become.&rdquo;
</blockquote>
With Ikigai in top form and his team behind him, there&rsquo;s no doubt that Alex Matz will be one to watch when the US Equestrian Open Final gets underway.

New Podcast: Alex Matz – Building a Career, One Round at a Time

The US Equestrian Open continues to highlight standout performances from the 2025 Winter Equestrian Festival (WEF), and this year&rsquo;s roster of multiple international winners is packed with talent from around the world. A total of 22 riders have already picked up multiple international wins during this season of WEF in Wellington. Just two of those are quadruple winners.
<img src="https://usef-admin.fly.dev/assets/66355ab9-7524-44ff-8288-ea851875e6c2.png?width=1086&amp;height=2080" alt="75 G Yb Rider With Multiple International Wef Wins in 2025 (1)">
<h2>Leaders of the Pack</h2>
Two riders have risen to the very top of the leaderboard with four international wins each: Luis Fernando Larrazabal (VEN) and Richard Vogel (GER). Their performances across a variety of classes demonstrate versatility and consistency and show great form to start off the 2025 season.
Luis Fernando Larrazabal has been in exceptional form, securing three victories aboard the ever-reliable Belle De Muze in the CSI 5* and CSI 4* 1.45m Wednesday classes. His fourth win came in the CSI 3* 1.50m Classic with Scarlett Du Sart Z.

 Richard Vogel has also claimed four victories, splitting his success between two horses: Phenyo Van Het Keysersbos and Cydello. Vogel&rsquo;s results include back-to-back Wednesday wins with Phenyo Van Het Keysersbos and Grand Prix triumphs aboard Cydello, demonstrating his mastery across mid-week classes and high-pressure weekend finales.

<h2> The Triple Winners</h2>
A total of 5 riders are already triple international winners at WEF.
The most notable of those is undoubtedly&nbsp;Kent Farrington, who picked up back-to-back five-star Grand Prix victories aboard Greya during WEF 5 and WEF 7, and also won the 1.50m Classic on the 9-year-old Grass de Mars during WEF 7. His ability to deliver on both experienced and developing horses underlines why he remains a force at the very top level.
McLain Ward continues to be a pillar of consistency, bringing his trademark precision to Winter Equestrian Festival. His 3 international victories of 2025 have brought his tally of international wins at WEF since 2010 to 60, making him the most prominent winner of WEF in the last decade. Also World #1, Henrik von Eckermann has proven that his brilliance extends to the Florida circuit with three strong wins, all aboard Glamour Girl.
<h2>The Double Winners</h2>
A further 18 riders have already posted multiple international wins at WEF 2025, a testament to the depth of talent on display. Familiar names like Ben Maher, Darragh Kenny, and Jessica Springsteen are joined by rising stars including Ireland&rsquo;s Tom Wachman and Tim Brennan, and the USA&rsquo;s Michael Murphy and Zayna Rizvi.
 The early part of the season has already offered drama, excitement, and remarkable performances&mdash;and with riders fine-tuning their peak form, fans can expect even more fireworks in the weeks ahead.
