On Thursday, a newly retained track expert will begin a thorough inspection of Santa Anita Park's racing surface.
The announcement came hours after a 4-year-old filly named Let's Light the Way was injured during training and had to be euthanized, becoming the 21st horse to die at the track since December 26th.
Racetrack officials say they'll conduct "additional extensive" surface testing and reevaluate safety measures during the closure.
Lets Light the Way, a filly trained by Ron McAnally, was injured during a workout around 7:45 a.m. McAnally told Daily Racing Form the filly suffered a "shattered sesamoid," a bone in the knee or foot, and the horse was euthanized a short time later.
"To me, it's the weather that is causing these breakdowns," McAnally told DRF. "This is the first one I've had (this winter)."
Lets Light the Way earned $18,500 in four starts, including one win at Santa Anita last April.
But they say everything checked out.
Experts peeled back the soil and even used “ground radar” to try to figure out why so many horses have died so far this racing season at Santa Anita last week.
Officials at Santa Anita shut down the track for racing until last Thursday, so they could take some samples in the wake of the 19th injury-related death of a horse there in just the past two months.
That's almost twice as many who died during the same time period last year.
Experts have examined the track at Santa Anita closely and they don’t believe the track itself was a factor in the deaths of 19 horses over the past two months.
Officials want to make sure the track-surface doesn't have any irregularities that could be causing problems for horses.
Mike Willman, who is with Santa Anita, says he believes it’s all about the weather.
"The track's surface is definitely something you have to look at and the 11 and a half inches of rain we've had is a big factor here," he said.
The track inspections have not turned up anything unusual.
Dr. Mick Petersonm is the director of Ag Equine programs at the University of Kentucky and said he’s been working with Santa Anita for more than decade.
The death of Charmer John, a 3-year-old gelding who was euthanized after he suffered a catastrophic injury to his left front fetlock, was the 19th horse death at Santa Anita since Dec. 26, according to the Times.
On Sunday, Tim Ritvo, chief operating officer of The Stronach Group, which owns the racetrack, allegedly reversed a decision made earlier in the day and agreed to allow the track to be open Monday until 9 a.m. after some trainers, including Hall of Famers Bob Baffert and Jerry Hollendorfer, objected to the closure and said they thought the track was safe.
"In conjunction with the California Horse Racing Board, Santa Anita Park has announced its main track will be closed for training beginning at 9 a.m. on Monday and all day Tuesday in order to fully evaluate sub-surface conditions such as moisture content and soil consistency," the park said in a statement Sunday that made no mention of any horse deaths. "If the results of these efforts indicate the track is in prime condition, regularly scheduled training will resume Wednesday morning and live racing will proceed on Thursday."
Sunday's statement went on to say that "in order to accommodate horsemen tomorrow, the main track will open for training beginning at 5 a.m., with two regular renovations scheduled at 6 a.m. and 7:15 a.m. Santa Anita's training track will be open each morning as planned, at 4:45 a.m. and will stay open until 10:30 a.m."
Alan Balch, executive director of the California Thoroughbred Trainers, said: "The decisions to close and reopen the track were made without consultation with our group and without us hearing the arguments, pro and con. With that said, we are committed to offering all the support we can to ensure the safety of our horses, jockeys and workers and stand ready to do whatever we can to help solve this tragic set of circumstances."
The park said Mick Peterson, a track and safety expert from the University of Kentucky, will perform testing and evaluate the racing surfaces.
The abnormal amount of rain that has fallen over Southern California this winter is considered a likely factor to any difficulty with the track.
Santa Anita officials did not immediately respond to a request for comment.
Battle of Midway, the Breeders' Cup Dirt Mile winner of 2017, was euthanized Saturday morning after suffering injuries sustained during a workout, according to Santa Anita's Ed Golden.
"A five-year-old bay son of Smart Strike trained by Jerry Hollendorfer for Don Alberto Stable or WinStar Farm, LLC, Battle of Midway was being pointed to the $12 million Dubai World Cup on March 30 with a possible start before that in the Grade I Santa Anita Handicap on March 9, (trainer Jerry) Hollendorfer had said just prior to the incident," Golden said Saturday.
Battle of Midway won eight of 16 career starts and was third in the 2017 Kentucky Derby.
