Top Kentucky Derby contender McKinzie has sustained an injury and won't start in the Santa Anita Derby, trainer Bob Baffert said a few minutes after the Dubai World Cup on Saturday night in Dubai.

Missing the Santa Anita Derby obviously would put McKinzie's status for the Kentucky Derby in doubt.

Baffert said it was unclear how McKinzie hurt himself and even what the exact nature of the injury is. McKinzie worked a strong five furlongs on Monday at Santa Anita but didn't come out to train Thursday.

Blended Citizen, the winner of the Jeff Ruby at Turfway Park in his most recent outing, worked Saturday morning at Keeneland as he prepares for next weekend's Blue Grass, in which he will attempt to definitively punch his ticket to the Kentucky Derby.

The Proud Citizen colt went five furlongs in 1:01 1/5 in company with new stablemate Arawak, a move that left jockey Kyle Frey "ecstatic."

"It was great, beautiful," Frey said. "He handles the dirt good, especially this surface."

A communication problem between the New York Racing Association and AmTote resulted in incorrect pick six information being announced several times late on the Friday card.

Racing analyst Andy Serling announced on-air following the eighth race of the nine-race program that there would be a $61,486 carryover into Saturday. A graphic on the simulcast feed stated the same information.

After the ninth race was run, announcer Frank Mirahmadi said the pick six paid $61,486. He then came back on-air and said that there would be a carryover. The graphic then reappeared.

ARCADIA, Calif. – Kenjisstorm and True Royalty are scheduled to start next in stakes here after each won an optional claimer Thursday at Santa Anita.

Kenjisstorm won his first start since July in a race at a mile. Ridden by Flavien Prat, Kenjisstorm stalked the early pace before prevailing by 2 1/4 lengths over graded stakes winner Free Rose. The first two finishers are candidates for the Grade 3 American Stakes at a mile on turf April 21.

ARCADIA, Calif. – The Grade 1 Santa Anita Derby on April 7 may have one of its smallest fields in recent history, and the presence of the two leading 3-year-olds in the nation – Bolt d’Oro and McKinzie – is largely to blame.

McKinzie and Bolt d’Oro, both Grade 1 winners as 2-year-olds, were first and second, separated by a head, in the Grade 2 San Felipe Stakes at 1 1/16 miles on March 10. McKinzie was disqualified and placed second behind Bolt d’Oro for causing interference in the stretch.

World Approval, the reigning champion male turf horse, worked a sharp five furlongs in 1:00.95 over the turf course at Palm Meadows on Friday morning in preparation for a start in the Grade 1, $300,000 Maker’s 46 Mile at Keeneland on April 13.

World Approval worked in company with the stakes-winning filly Let It Ride Mom, getting a final quarter in 24.29 seconds and galloping-out six furlongs in 1:14.20.

“The plan was to put a good, strong work in him today and it sounds like that’s what we got,” said Mark Casse, who was not at Palm Meadows on Friday.

Danny Gargan enjoyed a successful winter meet at Gulfstream Park and plans to keep a string of horses there year round, he said Thursday.

“Racing’s going in the right direction there,” Gargan said.

Gargan will have his main base in New York this summer, and he plans to have a presence in Kentucky during the fall.

“I’m looking at having a big stable in the fall in Kentucky,” Gargan said. ”People give you horses there.”

HALLANDALE BEACH, Fla. – Luis Saez hopes to ride the wave of a record-setting winter into a successful spring at Keeneland and summer in New York.

On Thursday, Saez rode seven winners from eight mounts on the Gulfstream card, coming within a neck of having a perfect day. It was the second time this meet Saez has won seven races on a Gulfstream card, equaling the record set by Jerry Bailey in 1995 and equaled by Tyler Gaffalione last summer. Saez also won seven races on Jan. 24.

Turning into the stretch at the Palm Meadows training center Friday morning, Enticed was about a length behind his stablemate First Commander, a maiden, in what was to be Enticed’s final workout before the Grade 2 Wood Memorial on April 7 at Aqueduct.

Trainer Kiaran McLaughlin, watching from the clocker’s stand, said of Enticed, “He’s likely to be second.”

Indeed, Enticed was only able to get within a neck of First Commander at the end of the half-mile work. Enticed was timed in 49.91 seconds.

HALLANDALE BEACH, Fla. – Caledonia Road, who has not started since her resounding victory in the Breeders’ Cup Juvenile Fillies on Nov. 4, will have her much-anticipated 3-year-old debut delayed again due to a virus she contracted earlier this month.
