Qual é a tradução de "high-stepping horse", como no texto abaixo?

He'll sit here all afternoon, all evening, all night and into the morrow. He'll sit here until he turns to dust. # Class C, one-thousand-dollar purse on the Widener course, and with Stout on top of Deep End there's no telling what could happen. Jolly Jack breaks too quickly and drops, while Suntime holds on gamely, but it's Deep End the aunts have their money on -- against Tony's advice-for Deep End is a handsome, high-stepping horse, a plucky sprinter who last week ran third and usually does even worse but today has that look of ambition in his eye.
