Hall of Fame trainer Jerry Hollendorfer was banned by the ownership of Santa Anita on Saturday after a fourth horse from his stable died — and the 30th overall — at the Southern California track. On the recommendation of a special panel convened to review horses’ medical, training and racing history, the track’s stewards scratched four horses trained by Hollendorfer that were entered to run Saturday and Sunday. A 4-year-old gelding trained by Hollendorfer was injured Saturday while exercising on the training track and was euthanized.
