BALTIMORE – Hall of Fame jockey Kent Desormeaux was replaced by Ramon Dominguez aboard longshot Tiger Walk for Saturday’s Preakness Stakes after Desormeaux failed a Breathalyzer test at Belmont Park on Friday and was removed from his three mounts by that track’s stewards.

“We’re trying to run a professional operation and can’t have any distractions this weekend,’” Tom Millikin, general manager for Kevin Plank’s Sagamore Farm, the owner of Tiger Walk, wrote on Twitter. “We spoke with Kent and wished him well.”

MIAMI – Musical Romance was not only the filly and mare sprint champion in 2011, she was a workhorse to boot, making 14 starts during her Eclipse Award-winning campaign that culminated with a victory in the Breeders’ Cup Filly and Mare Sprint.

But if Musical Romance is going to defend her title, both in the Breeders’ Cup and for divisional honors in 2012, she’s going to do so without the same type of workload she carried a year ago.

LOUISVILLE, Ky. – A day before some of his fellow Kentucky Derby rivals race in the Preakness Stakes, Prospective got back to business at Churchill Downs Friday, breezing five furlongs in company with stablemate Stealcase in 1:01.20.

Although badly outrun in the Derby, finishing 18th, 34 1/2 lengths behind victorious I’ll Have Another, merely finishing the race is a credit to Prospective and his rider, Luis Contreras, after the horse clipped heels early.

ETOBICOKE, Ontario – Proud of My Roots has blossomed this spring for the barn of trainer Brian Lynch.

On Sunday, Proud of My Roots will be seeking to add a stakes-winning chapter to her heritage when she faces fellow Ontario-sired 3-year-old fillies in the $125,000 Lady Angela at seven furlongs.

“This is her chance, to show us that she’s going in this direction,” said Lynch, who trains Proud of My Roots for the Ballycroy Training Centre of Steve Kemp.

VANCOUVER, British Columbia – Tarue Grit might be worth taking a stab at when he runs in a claiming race Sunday at Hastings. The $17,500 conditional claiming race for 3-year-olds and up going 6 1/2 furlongs drew nine horses and goes race six on the seven-race card that begins at 1:50 p.m. Pacific.

Trained by Lenore Dubois, Tarue Grit is coming off a fifth-place finish in a similar race, and his current form doesn’t stand out.

ETOBICOKE, Ontario – Kitty’s Got Class, who has never lost in restricted company, will meet Ontario-sired opposition Sunday at Woodbine in the $125,000 Lady Angela, a seven-furlong stakes for 3-year-old fillies.

Kitty’s Got Class graduated at first asking by eight lengths in September, and then took the Victorian Queen Stakes by six lengths Oct. 1. Three weeks later, she struck again in the six-furlong Fanfreluche Stakes, for which she got just a 58 Beyer Figure, which was well below the 70 she earned in the six-furlong Victorian Queen.

Freud’s Honour, a New Jersey-bred colt who took to the turf so well that he was able to upset open stakes company in his second try on the surface, begins his 4-year-old campaign in Sunday’s featured ninth race at Monmouth Park, a second-level optional $32,000 claimer scheduled for one mile on grass.

For the first five races of his career, three as a 2-year-old with John Tammaro and his first two starts last spring for Greg Sacco, Freud’s Honour was strictly a dirt sprinter.

FORT ERIE, Ontario – Trainer Michael Cohen, 51, has been has been working with his small Fort Erie stable for the past 10 years and looks forward to many more seasons at this historic oval.

When not at the Fort, usually in the spring or fall, Cohen is frequently found at Woodbine Racetrack in Toronto. Other sojourns over the years have been south of the border to such tracks as Thistledown in Cleveland and Beulah Park in Columbus, Ohio.

LOUISVILLE, Ky. – Some may theorize that Rogue Romance, coming off a fast victory at Gulfstream on March 21 following a layoff of more than13 months, subsequently bounced when seventh, beaten more than 29 lengths in the Grade 3 Ben Ali at Keeneland on April 22.

Don’t count trainer Ken McPeek among such believers.

“That wasn’t a bounce; that was a thud,” he said.

Sunday’s ninth race at Churchill Downs, a $60,600 third-level allowance at 1 1/16 miles on dirt, provides a prime opportunity for Rogue Romance to get back in form under conditions that suit him.

The Cartel Straw is fortunate to remain unbeaten after two starts in advance of Sunday’s $268,200 Kindergarten Futurity for Quarter Horses at Los Alamitos, her trainer says.

Juan Aleman was not particularly impressed by the filly’s start in time trials on May 6, even though she won a division by a half-length to claim a berth in the 300-yard final.

“If she breaks, she’ll be tough,” Aleman said. “She didn’t break all that sharp in the trials. She was standing a little off-balance. She has to break on top to get it done.”
