SARATOGA SPRINGS, N.Y. - Princess of Sylmar came out of her fifth-place finish in Friday’s Grade 1 Personal Ensign with a case of the thumps, an affliction associated with an electrolyte imbalance, trainer Todd Pletcher said Saturday morning.
“It’s probably more common in endurance horses from the research I’ve done,” Pletcher said. “It’s something we’ll see occasionally through the year from various horses. Most of the time, they don’t perform up to standards. It’s the first time we recognized it with her.”
