HOT SPRINGS, Ark. – The field for the Grade 1, $1 million Arkansas Derby was starting to grow Monday, with Falling Sky and Frac Daddy committing to the 1 1/8-mile race and Demonic’s connections debating a start in the Saturday stakes, which closes out the Oaklawn meet.

Two more Grade 1 3-year-old prep races were showcased on Saturday, April 6 as contenders continued to rise and fall one month away from the 139th running of the Kentucky Derby.

There are less than four weeks until the Kentucky Derby, do you know who’s riding your horse?

For the connections of many of the top contenders, the answer as of Monday afternoon was no.

OZONE PARK, N.Y. - West Hills Giant, the runner-up in the Grade 3 Gotham Stakes here on March 2, appears fully recovered from the respiratory infection that forced him to miss a workout a few weeks ago and last Saturday’s $1 million Wood Memorial.

On Monday, West Hills Giant drilled five furlongs in 1:00.47 on the Belmont training track under exercise rider Simon Harris, and later that afternoon was put on a van bound for Lexington, Ky., and Saturday’s Blue Grass Stakes.

ARCADIA, Calif. – The first three finishers from the Wood Memorial all are set to head to Kentucky, and quite soon, but the Santa Anita Derby might have the victorious Goldencents as its lone representative in the May 4 Kentucky Derby, the result of injuries to two top West Coast contenders both before and after the Santa Anita Derby.

LEXINGTON, Ky. – Chad Brown is swapping out Noble Tune in favor of Balance the Books for the Blue Grass Stakes, a move that changes up things in his own stable – but not the bulkiness of the field for the 89th running of the Keeneland showcase Saturday.

Keeneland officials are expecting more than the 14-horse limit when entries are drawn Wednesday at the annual media breakfast for the Grade 1, $750,000 Blue Grass, a situation that likely will necessitate having an also-eligibles list for the 1 1/8-mile Polytrack race.

It’s possible the clock has already struck midnight for Footbridge’s Kentucky Derby dreams as the Darley homebred’s last-minute blitz on Saturday’s Blue Grass Stakes may be denied because of the possibility of an overflow field. If the 100-point Kentucky Derby race is oversubscribed, maiden winner Footbridge could be excluded from the body of Keeneland’s signature event.

Flashback, who finished second to Goldencents in the Santa Anita Derby on Saturday, was found on Sunday afternoon to have a small chip in his right knee, trainer Bob Baffert said Sunday night. He is off the Kentucky Derby trail, but is expected to make a full recovery after having surgery in Kentucky with Dr. Larry Bramlage.

"There was heat in his right knee and we took X-rays and had them sent to Bramlage," Baffert said Sunday night. "He's got a chip. It's small. It's fresh. When you take it out right away they can make a full recovery."

MANHASSET, N.Y. - Hall of Fame jockey John Velazquez fractured a rib on his right side and chipped a bone in his right wrist as a result of being involved in a spill Sunday at Aqueduct.

 While Velazquez will not be able to ride Horse of the Year Wise Dan in his seasonal debut in Friday’s Maker’s 46 Mile at Keeneland, Velazquez said he hopes to be back in time to ride the Kentucky Derby.
