Diamond Omi, the winner of the Grade 2 Oak Leaf Stakes at Santa Anita in October, died of complications of pneumonia on Thursday night, trainer Bob Baffert said on Friday.

was one of the top 2-year-old fillies in the nation this year.

Owned by Don Dizney, Diamond Omi finished 10th in the Breeders' Cup Juvenile Fillies at Belmont Park on Oct. 29, her final start. She won 2 of 5 starts and $160,740.

Diamond Omi was at the Chino Valley Equine Clinic in Southern California at the time of her death.

"They were trying to save her. She'd been sick since three days after the Breeders' Cup," Baffert said. "She'd been at the clinic for more than two weeks. I got a call and they said she didn't make it."

Baffert said that Diamond Omi's health fluctuated in recent weeks, took a turn for the better recently, but declined in recent days.

"She had a lung that was abscessed and that was a bad deal," Baffert said. "I feel so bad for Don. They got a good one and it's so hard to get a good one."

Diamond Omi beat maidens in her third start at Del Mar on Sept. 7. She returned to pull an 8-1 upset in the Oak Leaf Stakes, her stakes debut.
