2-year-old filly Diamond Omi dies

The 2-year-old filly Diamond Omi, 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.

Owned by Don Dizney, 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," Baffert said. "She'd been sick since three days after the Breeders' Cup. 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 had taken a turn for the better, but then 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 at Del Mar in her third start on Sept. 7. She returned to pull an 8-1 upset in the Oak Leaf Stakes, her stakes debut.
