Fair Grounds in New Orleans and Sam Houston Race Park in Houston were among the latest casualties of the coronavirus outbreak last weekend, with both tracks announcing that they would close without finishing their meets this year.The list of major tracks that continue to run live includes Santa Anita and Golden Gate in California, Oaklawn Park in Arkansas, and Gulfstream Park and Tampa Bay Downs in Florida. Fonner Park in Nebraska, Charles Town Races in West Virginia, and Remington Park and Will Rogers Downs in Oklahoma also continue to run live races, spectator&#45;free.Several major stakes, however, have been shifted or modified due to the outbreak and the rescheduling of the Kentucky Derby to Sept. 5. The Arkansas Derby at Oaklawn has been moved to May 2 and its purse has been cut from $1 million to $750,000. The Florida Derby at Gulfstream, to be run Saturday, had its purse cut from $1 million to $750,000 too.Both races are traditional prep races for the Derby. Purses at both Oaklawn and Gulfstream are subsidized by casino operations at the tracks, and those casinos have been ordered closed because of coronavirus.Fair Grounds canceled the remainder of its meet after running its Saturday card, which included the track&rsquo;s most prominent race, the Louisiana Derby. The track was scheduled to run through March 28. The track said that it would remain open for training until April 11.The Fair Grounds cancellation was announced one day after the Louisiana Horse Racing Commission passed an emergency measure requiring tracks and training centers in the state to allow horses and backstretch employees to &ldquo;shelter in place&rdquo; for at least the next 30 days. Sam Houston announced on Sunday that it would cancel the four remaining days in its meet and canceled the Quarter Horse meet scheduled to open on April 10. The track had to cancel most of its Saturday night card when a transformer providing power to the track malfunctioned, creating a lighting issue. Also last weekend, Indiana Grand reversed a decision requiring horses to vacate the track, an order that was issued after the track postponed the start of its live racing meet, which was scheduled to start on April 14. Approximately 100 to 150 horses are currently stabled at Indiana Grand.
