DEL MAR, Calif. - Tuscan Evening, winner of six stakes for turf females earlier this year, died after a workout on Aug. 8 from acute pulmonary hemorrhage, according to Dr. Rick Arthur, the equine medical director of the California Horse Racing Board. Arthur said Wednesday that the diagnosis was made after a necropsy. He said such incidents are rare. “We get a few each year, as many in training and racing,” he said. “This does happen.” Tuscan Evening is a leading contender for the Eclipse Award as the nation’s outstanding turf female. Owned by Will de Burgh and trained by Jerry Hollendorfer, Tuscan Evening won 12 of 27 starts, including nine stakes, and earned $1,138,508 in her career.
