Hollendorfer was an American Currency trainer
This is the 30th horse death at Santa Anita since this racing season began in December.
Four of those horses were trained by Hollendorfer.
The Stronach Group, which owns Santa Anita, has issued a statement saying in part, "We regret that Mr. Hollendorfer's record in recent months at both Santa Anita and Golden Gate Fields (near Oakland, California) has become increasingly challenging and does not match the level of safety and accountability we demand
" Effective immediately, Mr. Hollyndorfer is no longer welcome to stable, race or train his horses at any of our facilities. "
The action comes a day after CNN aired an investigation into horse deaths at Santa Anita and other racetracks around the country. According to Horsebike Racing website Equibase, American Currency raced five times earlier this season at Golden Gate Fields before he raced at Santa Anita, once in May. There were 10 races scheduled for Saturday's program, the next day of the season.
The track is scheduled to host one of the race's biggest events, the Breeders Cup, in November at the end of its autumn season. ]
