Kierstin Antoniadis and Pokerface Are All In to Win Inaugural USHJA Pony Hunter Derby Championship-East

Lexington, Ky.—August 5, 2019—Riding Winter Tietjen’s Pokerface, Kierstin Antoniadis earned the top scores in the Classic Hunter Round and Handy Hunter Round to win the inaugural USHJA Pony Hunter Derby Championship-East, during the Kentucky Summer Classic, August 4, at the Kentucky Horse Park in Lexington.

“It feels pretty awesome because I’ve known this pony for over a year now, and I feel like we’ve kind of figured each other out between then,” said Antoniadis after her big win. “He’s a really special pony to me so it was really cool winning all of this today.”

Earning an 87 and an 88 in the Classic Hunter Round, Antoniadis took the lead on the Large 11-year-old Dutch Riding Pony, trained by Shannon Cunneff. The now working student for Andre Dignelli at Heritage Farm pulled from her equitation experience for the Handy Hunter Round. 

“I definitely tried to shave off as much space as I could while still making it look smooth,” said Antoniadis. “I think the judges—which I’ve learned a lot from the equitation is when you come off a trot jump or a sharp turn and then you’re going to a long single jump—they really want to see a change in pace and some type of ambition and I think that really helped me with him.”

Going all in for the Handy Round, Antoniadis’ boldness paid off earning her scores of 85 and 90, securing her spot as the inaugural Champion, as well as the Overall High Score Award winner for the Large section. As the overall Champion, Antoniadis also won a tack trunk from Sea Horse Tack Trunks, a belt from Boy O Boy Bridleworks, a show shirt from Essex Classics, and a gorgeous custom floral blanket from Champion Floral Blankets by Susan Garrett.

Vivian Golden’s consistency on Hidden Springs Waltz, a Medium 12-year-old Welsh Pony Cross gelding, owned by Renaud Farm LLC, earned her the Reserve Champion title with an average score of 84.87 in the Classic Round and an 84 in the Handy Round. As the Reserve Champion, Golden received a tack trunk from Sea Horse Tack Trunks, and a belt from Boy O Boy Bridleworks. Golden also earned the High Score Award for the Medium section and finished in 12th place aboard her own Goldhills As You Like It.

As the third place finisher, David rode away with prizes from sponsors including a grooming tote from Sea Horse Tack Trunks and a belt from Boy O Boy Bridleworks.
