Stuart Black celebrated his new U.S. citizenship by riding Fleeceworks Starlight to a faultless show jumping round on Sunday at the Radnor Hunt CCI** in Malvern, Pa. And it put pressure on the two leaders–Mara Dean and Ralph Holstein–that they couldn’t overcome.

Dean and Good Stuff lowered fence 4, a liverpool oxer that fell a couple of dozens times this afternoon, and settled for second place, while Holstein and Arctic Dancer lowered fences 2, 4 and 6 and added 1 time fault to drop to fifth.

It was Black’s third Radnor victory–he also won in 1993 and 1995–but the first two were as a Canadian. Radnor was his first international event since becoming an American.

“It was certainly a wild experience to sit there for the American national anthem” in the awards ceremony, said Black, 45. His wife, Momi, and 14-month-old daughter Kayleigh joined him there.

Dean, who’d taken the lead during Thursday’s first day of dressage, blamed their miscue on “his greenness and my nervousness.” Holstein, just 19, never seemed to find a rhythm with Arctic Dancer.

Clean rounds–there were only six from the 64 starters today–moved Liza Horan of Unionville, Pa., and Sharon White of Summit Point, W.Va., up to third and fourth places.

Horan said Johnny McCarthy jumped faultlessly because “he can be a bit spooky, but that spookiness is what makes him more careful.”

White and O.K. Charlie won the best-conditioned award, determined by the veterinary panel. Nathalie Bouckaert and Everest, who dropped from fifth to 12th by dropping four rails, won the best turned-out award.

Wendy Bebie of Round Hill, Va., won the Paddington Award as the best-placed adult amateur who finished on her dressage score. With faultless cross-country and show jumping rounds, she and Phoenix finished 14th.

The Radnor organizers also ran two preliminary horse trials divisions concurrently with the CCI**. Linden Wiesman finished first and third in division A on Into The Future and On A Tear, while David O’Connor won division B with Walk On The Moon.
