So Happy went on to deliver Mark his first Santa Anita Derby victory, qualifying the pair for the 2026 Kentucky Derby. Mark called it his biggest career win, though he admitted it was emotional without Dena there to celebrate. He wears a bracelet containing some of her ashes so she can always be with him.
