Grade 1 winner Hard Not to Love was retired this week after disappointing results in two graded stakes at Santa Anita this year.
Trainer John Shirreffs said Hard Not to Love was flown to Kentucky on Friday.
The decision was made in recent days after Hard Not to Love worked five furlongs in 1:02.40 on Tuesday at Santa Anita, a slower-than-expected clocking.
“She seemed like she wasn’t quite as good as she was before,” Shirreffs said. “She’d been in training a long time without a break. It seemed like it was time to stop.”
