ARCADIA, Calif. - Prominent owner Kaleem Shah and Hall of Fame trainer Bob Baffert have parted ways, Baffert said in an email Saturday evening.

Baffert wrote in a four-paragraph statement that he and Shah "have ended their business relationship," effective Saturday. Baffert declined to elaborate when reached via text Saturday evening.

Shah said in a phone interview that trainers Doug O'Neill and Art Sherman will be his new trainers. He did not disclose a reason for the breakup with Baffert, but expressed disappointment that their partnership was ending.

A second horse at Fair Grounds has gotten sick and tested positive for the equine herpesvirus, senior director of racing Jason Boulet said Saturday morning.

The herpes positive comes five days after one barn at Fair Grounds was put under quarantine because a horse died from the virus. That horse, trained by Alice Cohn, was housed in barn 14, as was the second horse to be infected, one trained by Jeff Thornbury.

Rudy Rodriguez holds a strong hand in this race. The morning-line favorite is Miggsy (#6), who put in a strong effort in his debut, making a midrace move around the turn before flattening out in the stretch. While he finished a decent second that day, he did work out a perfect trip, so you have to wonder how much he can move forward off that effort.

Heatseeker, a California-based stallion who won the Grade 1 Santa Anita Handicap in 2008 and two other graded stakes, was euthanized on Tuesday as a result of a recent injury suffered in a paddock accident at Harris Farms in Coalinga, Calif., the farm announced Friday.

The board of directors of the local Horsemen's Benevolent and Protective Association has notified management of Finger Lakes Gaming and Racetrack that it has withdrawn its permission for the facility to conduct simulcast wagering as of Jan. 1.

The simulcast embargo will begin a month before the new Del Lago Resort and Casino is set to open 27 miles away from Finger Lakes. The new casino is expected to dramatically reduce business at the Finger Lakes casino.

Regally Ready, the Breeders’ Cup Turf Sprint winner in 2011, has been retired and is now based in Ocala, Fla., trainer Steve Asmussen said Thursday.

Regally Ready, a gelding who turns 10 on Sunday, won 20 of 48 starts and had earnings of $1.8 million. Nine of his wins came in stakes, including the Grade 1 Nearctic at Woodbine. Regally Ready, a son of More Than Ready bred by Grapestock, raced throughout his career for Vinery Stables.

“He made a lot of people happy,” said Asmussen.

ARCADIA, Calif. - Masochistic was formally disqualified on Friday from a second-place finish in the $1,365,000 Breeders’ Cup Sprint at Santa Anita on Nov. 5 because of the presence of a banned steroid.

“We will disqualify the horse,” said Chaney, who officiated the hearing.

OZONE PARK, N.Y. – For the second consecutive year, the New York Racing Association will offer $100,000 purses on some of its maiden races for 2-year-olds during the 2017 Aqueduct and Belmont Park spring meetings.

ARCADIA, Calif.- For the second consecutive racing program, the pick six proved too tough to hit at Santa Anita on Thursday.

There are two rich carryovers in the pick six for Friday’s program - $361,436 in the main pool and $77,450 in the single ticket jackpot pool.

The winter-spring meeting began on Monday, a day in which there were no winning tickets in the pick six.

Friday’s pick six covers the third through eighth races on a program that begins at 12:30 p.m. Pacific.

The pool of new money in the pick six is likely to surpass $1.3 million.

The IRS and the U.S. Department of the Treasury on Thursday issued proposed new rules that would greatly benefit horseplayers by allowing bettors to count all wagers made in a specific pool for the purposes of determining whether federal tax reporting and withholding requirements are triggered.

The proposed new rules, which were aggressively pursued by the National Thoroughbred Racing Association over the past two years, will be subject to a 90-day comment period. In a statement, the NTRA said it was “conceivable” that the new rules will be in place by late spring.
