LOUISVILLE, Ky. – Shamrock Rose, last year’s champion female sprinter, exited an April 19 workout at Keeneland with an ankle injury that could lead to her retirement, trainer Mark Casse said Sunday at Churchill Downs.
“I don’t know whether she is going to run anymore or not,” Casse said. “She’s done so much. She could come back, but by the time she comes back, we’re talking about fall and everything.”
