Since 2017, Matz and Cashew CR formed a highly successful partnership. They recorded wins at major events including the Devon Horse Show, Hampton Classic, The Highlands Cup, Lexington, Saugerties, Spruce Meadows, Upperville and Wellington. The 2025 season was particularly strong, with the pair securing seven international victories, Toronto being the final highlight.

Over the years, Cashew CR became the horse that carried Matz through every level of the sport, from national amateur classes to the top five-star circuit. Remarkably, he maintained his competitiveness well into his senior years. The gelding is held in high regard within the Matz family and the team at their Pennsylvania base, known for his consistency and strong work ethic.

With Cashew CR now returning home to Pennsylvania, his career concludes as a model example of longevity and success in sport. The pair developed steadily across many seasons, leaving behind a record of achievements that reflects a reliable and accomplished competition horse.
