Zenyatta had a quiet day at trainer John Shirreffs’s stable on Thursday, a day after it was announced that she has been retired and will be relocated to Lane’s End Farm near Versailles, Ky., in December.

Zenyatta was walked twice Thursday morning and was scheduled to have another walking session in the afternoon.

A two-time champion, she retires with 19 wins in 20 starts, with her only loss a second to Blame in the BC Classic on Nov. 6.

Promise Me a Cat figures to get an ideal trip Saturday in the Grade 3, $500,000 Delta Downs Princess. She is one of the speediest fillies in the one-mile race, and she figures to fall into a stalking position on the move from a six-furlong stakes win at Belmont Park to the six-furlong oval in Vinton, La.

“She’s pretty adaptable as far as rating tactics, and she’s got tactical speed, which I think you need at Delta,” said Carlos Martin, who trains Promise Me a Cat for Mark Holiday.

Sweeping changes have been made to Saturday’s Grade 3, $1 million Delta Downs Jackpot in an effort to increase its visibility, and the race that will be put on Saturday in the small Louisiana town of Vinton should catch the attention of handicappers nationwide. Eight stakes winners are in the 10-horse field, with 2-year-olds shipping in from California, Delaware, Florida, Kentucky, New Jersey, New York, and Texas.

INGLEWOOD, Calif. − Special Duty, the winner of the English 1000 Guineas and French 1000 Guineas in May, will make her U.S. debut in the $250,000 Matriarch Stakes at Hollywood Park next Friday.

Trained by Criquette Head-Maarek for Juddmonte Farms, Special Duty has won 4 of 9 starts and $1,070,938. The Matriarch Stakes, over a mile on turf for fillies and mares, will be Special Duty’s first start since she finished sixth behind Goldikova in the Group 1 Prix de la Foret over seven furlongs on turf at Longchamp in Paris on Oct. 4.

STICKNEY, Ill. – The good news at Hawthorne Race Course this fall? Handle has ticked modestly up from the fall-winter meeting last year, and, thanks in part to four-day race weeks this season, Hawthorne is awash in horseflesh. The quality of those horses, however, has fallen steeply compared to past meetings. Saturday’s card looks about typical, with the lone allowance race for Illinois-bred entry-level allowance horses.

When All American Futurity winner Mr Piloto starts in Saturday’s 11th race at Los Alamitos, there will be two trials left for the Los Alamitos Two Million Futurity for Quarter Horses.

The 12-race program at Los Alamitos on Saturday is dedicated to 400-yard trials for the Los Alamitos Two Million. The 10 fastest times, regardless of finishing positions, will earn berths for the final Dec. 10.

Already a stakes winner in Panama and Canada, Golden Moka looks to break through in the United States when he faces six rivals Saturday in the Grade 3, $100,000 Discovery Handicap for 3-year-olds at Aqueduct.

Golden Moka has the rail in the 1 1/8-mile race.

The chestnut colt, a modest $8,000 yearling purchase at Keeneland in 2008, is 4 for 5 in his brief career.

He swept all three races last year in Panama, including a Grade 3 stakes. Golden Moka lost training time earlier this year when he got sick after shipping to Canada and trainer Brian Lynch.

INGLEWOOD, Calif. – He is not exactly revealing trade secrets, but jockey Alonso Quinonez has a plan for how to ride Premier Pegasus in Saturday’s $100,000 Hollywood Prevue Stakes.

“I think it will be easy to get the lead and then he can relax,” Quinonez said. “I shouldn’t say that. Now, the other jockeys will know.”

Quinonez has ridden Premier Pegasus to wins in both the colt’s two starts – a 44-1 upset in a maiden race at Del Mar over 5 1/2 furlongs on July 24 and a front-running win in the Jack Goodman Stakes over six furlongs here Oct. 23.

MIAMI – There are no stakes races on Saturday’s program at Calder but there are certainly plenty of stakes-quality horses entered in the afternoon’s eighth event to be decided under money allowance conditions at 7 1/2 furlongs on the turf.

OCEANPORT, N.J. – Chirac, making the third start of his comeback, tops the field Saturday in the $70,000 Frisk Me Now Stakes as the Monmouth Park season comes to a close.

This is the final weekend as the meet concludes Sunday.

Chirac will try to regain the form that made him a star here last season. He won four times at Monmouth in 2009, including the Grade 3 Iselin Stakes by a rousing 6 3/4 lengths.
