Chamberlain Bridge, winner of the 2010 Breeders’ Cup Turf Sprint, has been retired from racing, trainer Bret Calhoun said Friday.

Bred in Kentucky by Eugene Melnyk and owned by the Carl R. Moore Management Co., Chamberlain Bridge specialized in turf sprints, winning 19 of 53 starts for earnings of $1,953,016. The 9-year-old gelding finished eighth in the Sept. 2 Turf Monster at Parx Racing in his final career start.

“He retired 100 percent sound,” Calhoun said. “He just couldn’t compete at the top level anymore. He was a very special horse to all of us.”

Wine Princess – the 4-year-old filly who has a Horse of the Year for a mom and dad – has been sold privately to Hill ’n Dale Farm and likely will have two more starts before being bred next year.

Trainer Steve Margolis said he intends to run Wine Princess in the Chilukki Stakes on Nov. 2 at Churchill Downs, “followed hopefully by the Falls City” on Nov. 28. The filly will continue to run in the name of Becky Winemiller until being moved to Hill ’n Dale.

ARCADIA, Calif. - A combined Sunshine Millions-California Cup Day will be run at Santa Anita on Jan. 25.

Earlier this year, officials with the California Thoroughbred Breeders Association announced that the California Cup, held annually each autumn since 1990, would be merged with the Sunshine Millions Day stakes for California-breds.

On Jan. 25, there will be seven stakes, with three $250,000 races – the California Cup Classic for older horses over 1 1/8 miles, and the Cal Cup Derby for 3-year-olds and Cal Cup Oaks for 3-year-old fillies, each over 1 1/16 miles.

ARCADIA, Calif. - Trinniberg, winner of the 2012 BC Sprint, worked a half-mile in a quick 46.60 seconds on Friday, the fastest of 21 works at the distance.

The workout was the first for Trinniberg since he finished last of seven in the Grade 1 Santa Anita Sprint Championship on Oct. 5. Trained by Bisnath Parboo, Trinniberg was ridden in the workout by Kevin Krigger, though it was unclear as of Friday morning who would ride Trinniberg in the $1.5 million BC Sprint on Nov. 2.

ARCADIA, Calif. - Santa Anita Derby winner Goldencents worked five furlongs in 59 seconds Friday for a scheduled start in the $1 million BC Dirt Mile on Nov. 1. The Grade 1 BC Dirt Mile will be Goldencents’s first start around two turns since a fifth-place finish in the Preakness Stakes at Pimlico on May 18.

Since the Preakness, Goldencents has been second three times, all in sprints, including a runner-up finish to Points Offthebench in the Santa Anita Sprint Championship on Oct. 5.

Trainers Henry Dominguez and Danny Pish operate two of the winningest stables at their respective bases of New Mexico and Texas. Next month, both will chart new territory with starters in the Breeders’ Cup.

Dominguez, 55, is pointing Wine Police for the $1.5 million Sprint on Nov. 2, and has secured Rafael Bejarano to ride. Pish, 47, will send out Got Shades in the $1 million Juvenile Turf on Nov. 1, and has given the mount to Gary Stevens.

ARCADIA, Calif. – Mizdirection, winner of the 2012 Breeders’ Cup Turf Sprint, was described by trainer Mike Puype as “100 percent” ready for this year’s $1 million BC Turf Sprint after working seven furlongs in 1:24 on turf Friday at Santa Anita.

Ridden in the workout by Hall of Fame jockey Mike Smith, Mizdirection worked the opening quarter-mile in 23.80 seconds, five furlongs in 59, and six furlongs in 1:11.20, according to track clockers. Puype said that Mizdirection will have one more workout next weekend before the BC Turf Sprint here Nov. 2.

Trainer Roger Attfield also is looking forward to next Sunday with Forte Dei Marmi and Perfect Timber on target for the $1 million Canadian International and Moment of Majesty set for the $500,000 E.P. Taylor Stakes.

Both the 1 1/2-mile Canadian International, for 3-year-olds and up, and the 1 1/4-mile E.P. Taylor, for fillies and mares, are Grade 1 turf races.

The fillies Irish Mission and Nancy O are the only other locals slated to compete in the Grade 1 features, with Irish Mission nominated to both races but with a current lean to the Canadian International.

ELMONT, N.Y. – Though Artemis Agrotera won the Grade 1 Frizette here at Belmont Park on Oct. 5, most of the talk immediately following the race was about the trouble favored Sweet Reason overcame to be second.

While Mike Hushion, the trainer of Artemis Agrotera didn’t want to speculate about the outcome of the Frizette, “it would have been very interesting if she came to our neck what my filly would have done,” Hushion said.

Perhaps that circumstance will play out in the Breeders’ Cup Juvenile Fillies at Santa Anita on Nov. 2.

STICKNEY, Ill. – For handicappers, one the most pressing questions early in Hawthorne’s fall-winter meet is which horses that have run well over Arlington’s synthetic Polytrack surface will transfer their form to dirt. Direct form correspondence between the two surfaces is rare, and can lead to heavy favorites going down in flames, and horses that looked hapless on the other side of Chicagoland coming in at long odds.
