Horse racing notes: Old Fashioned retired; Leparoux will ride General Quarters

One-time Kentucky Derby favorite Old Fashioned has been retired from racing after knee surgery.

The 3-year-old colt injured the knee following a second-place finish in the Arkansas Derby at Oaklawn Park on Saturday.

Surgery was performed Tuesday at Rood & Riddle Equine Hospital in Lexington.

Old Fashioned won his first four races and was considered an early favorite for the Kentucky Derby on May 2. The colt then finished second in the Rebel Stakes on March 14 before his runner-up finish in the Arkansas Derby.

Leparoux picked to ride General Quarters in Derby

LOUISVILLE — Toyota Blue Grass Stakes winner General Quarters will be ridden by Julien Leparoux in next month's Kentucky Derby.

General Quarters surprised the field in last week's Blue Grass with Eibar Coa aboard, but owner/trainer Tom McCarthy decided to give the Derby start to Leparoux after Coa wouldn't commit to General Quarters for the May 2 Derby.

Coa is also the regular rider for likely Derby entry Musket Man, winner of the Illinois Derby.

McCarthy said Leparoux's success at Churchill Downs was a major factor in the decision. The 25-year-old Frenchman won a record 63 races during the track's 2008 Fall Meet.

Leparoux has made two previous Derby starts. He finished fifth aboard Sedgefield in 2007 and 15th aboard Cool Coal Man last year.

Pioneerof the Nile works

ARCADIA, Calif. — Santa Anita Derby winner Pioneerof the Nile has completed his final workout in California before heading to Churchill Downs for the Kentucky Derby.

Under exercise rider Joe Steiner, the colt ran 4 furlongs on Santa Anita's synthetic surface in 46.20 seconds, fastest of 30 drills at the distance.

Trainer Bob Baffert said the colt did it "pretty damn easy" and that it was probably the best Pioneerof the Nile had ever worked.
