Oak Leaf: Diamond Omi pulls upset

ARCADIA, Calif. - Diamond Omi pulled an upset in the $200,000 , edging the previously unbeaten Wild Fit after a stretch-long duel.

Diamond Omi ($19.40) ran 1 1/16 miles in 1:45.57, scoring by three-quarters of a length over 1-2 favorite Wild Fit, who finished 4 1/2 lengths clear of Golden Silk in the field of seven 2-year-old fillies.

The first two finishers are expected to start in the Breeders' Cup Juvenile Fillies at Belmont Park on Oct. 29.

The Grade 2 Oak Leaf was Diamond Omi's stakes debut and first start since winning a maiden race over a mile by 3 1/2 lengths at Del Mar on Sept. 7.

Ridden by David Flores in the Oak Leaf, Diamond Omi was always near the front, stalking pacesetter Golden Silk through early fractions of 23.20 and 47 seconds. On the final turn, Diamond Omi took the lead while racing on the rail.

Wild Fit, the winner of the Del Mar Debutante in her previous start, was within a half-length of Diamond Omi at the eighth pole, but could not close the gap.

Wild Fit was near Diamond Omi on the backstretch, racing within two lengths of the front. Trainer Jeff Mullins expected Wild Fit to be farther back in the first half-mile.

"She was a little too eager," Mullins said. "She was pretty keen early, and I think that took away from her kick."

Diamond Omi has won 2 of 4 starts and $160,470. Owned by Donald Dizney, Diamond Omi has been among trainer Bob Baffert's well-regarded 2-year-old fillies since the summer.

"She was supposed to run like that her first race," Baffert said. "I told Don Dizney to come out to watch her run, but she ran horrible. I told him, 'I'm sorry.' "

Baffert said he expects further improvement from Diamond Omi.

"She's not there yet, but she's got a lot of quality," Baffert said.

* Siren Lure ($9.40) edged Geronimo by a head in the $71,000 Blue Jay Way Stakes for turf sprinters.

Ridden by Rene Douglas, Siren Lure ran about 6 1/2 furlongs on the hillside course in 1:11.95. Geronimo finished three-quarters of a length in front of 10-1 Crystal Castle in the field of 10.

Siren Lure, who races for a partnership and trainer Art Sherman, won the Kerlan Memorial Handicap at Hollywood Park in July. In his career, Siren Lure has won 7 of 14 starts and $238,771.
