ARCADIA, Calif. – Arrogate completed his serious training for the $10 million Dubai World Cup on March 25 with a strong seven-furlong workout Sunday morning at Santa Anita in 1:25, an outstanding time considering the track was slower than usual.

Arrogate came on the track just after the mid-morning renovation break with stablemate Cat Burglar, and, after they jogged and galloped through the homestretch they immediately broke off at the 6 1/2-furlong pole, with Arrogate initially about two lengths back.

Oaklawn on Sunday announced an overnight purse increase for the final month of the meet that will push the value of maiden special weights to $80,000 from the current $72,000, while allowances will be worth as much as $84,000 from the previous level of $76,000.

The increases will begin with the Rebel Day program on Saturday.

ARCADIA, Calif. – Mastery, injured when winning the Grade 2 San Felipe Stakes on Saturday at Santa Anita, was scheduled for surgery Monday morning at Santa Anita, a gut-wrenching turn of events for his connections who thought they had the favorite for the Kentucky Derby when he crossed the wire, then immediately had to turn their focus to getting him through the surgery.

His trainer, Bob Baffert, said Mastery was “stabilized” in his stall Sunday. “Now we have to take good care of him, get him right,” Baffert said. “I’ll feel a lot better after they do the surgery.”

OZONE PARK, N.Y. – The typical apprentice jockey is barely old enough to shave or vote and most certainly is not of legal drinking age. At age 27, Hector Diaz Jr. is not your typical apprentice jockey.

Sure, he went to the same jockey school in Puerto Rico as Irad Ortiz Jr. and Jose Ortiz – Diaz’s cousins – and Manny Franco, but he did not ride races there. In fact, the first time Diaz rode a horse in a sanctioned race, he finished second aboard Shoppingforsilver in a $16,000 claiming race at Aqueduct last Nov. 11.

ARCADIA, Calif. – Hall of Fame jockey Gary Stevens was winless in two mounts at Santa Anita on Thursday, his first rides since undergoing hip-replacement surgery in late December.

Stevens finished second on Oopper Wallah in the fourth race, for 3-year-old claiming sprinters, and sixth on Jabber Now in the eighth race, for maidens on turf. He was active in the Santa Anita stables on Friday morning.

“I’ve worked a couple, and I’m ready for today,” he said.

ARCADIA, Calif. – Stellar Wind, the 2015 champion 3-year-old filly, worked five furlongs in 1:00.20 at Santa Anita on Friday, an exercise trainer John Sadler described as “sensational.”

“We asked her to do a little more,” Sadler said. “She looked super-duper.”

Owned by Pete and Kosta Hronis, Stellar Wind is scheduled to have her 2017 debut in the Grade 1 Apple Blossom at 1 1/16 miles at Oaklawn Park on April 14.

ARCADIA, Calif. – Decked Out, unraced since winning the Grade 1 American Oaks at Santa Anita on Dec. 31, is getting a three-month break and will resume training in the spring, trainer Keith Desormeaux said Friday.

Decked Out has been at Piecefield Farm in Southern California since mid-February and will be there until May.

“She’s on a little break,” Desormeaux said. “We’ll point for a fall campaign.”

Decked Out had two recorded workouts at Santa Anita in early February before Desormeaux opted to give the filly a rest.

ARCADIA, Calif. – Battle of Midway and Reach the World finished a neck apart in an optional claimer for 3-year-olds in Thursday’s seventh race at Santa Anita. There is a good chance they will see each other again in early spring.

Trainers Jerry Hollendorfer and Bob Baffert said they are strongly considering the Grade 1 Santa Anita Derby on April 8 for both colts, who had their third career starts Thursday.

HOT SPRINGS, Ark. – The field for the Grade 2, $900,000 Rebel Stakes came into clearer focus Friday at Oaklawn, where potential starters Petrov, Uncontested, and Silver Dust put in works for the Kentucky Derby points race set for next Saturday.

The Rebel will share a card with two other stakes, the Grade 2, $350,000 Azeri for fillies and mares and the $250,000 Essex Handicap. Nominations for the three races were to close Friday, with entries to be taken Wednesday. The card generally ranks as the second-biggest of the meet, behind Arkansas Derby Day on April 15.

HALLANDALE BEACH, Fla. – Elizabeth Dobles has had her trainer’s license for only a few months. But it didn’t take the 26-year-old long to make a big impression at Gulfstream, winning both ends of Thursday’s late daily double with longshots Arty’sbourbongirl and Swapl.

Dobles, who also gallops her horses, served as an assistant in New York for trainer Jeremiah Englehart before striking out on her own this winter.
