Intrepido (Maximus Mischief) and Robusta (Accelerate), both targeting Saturday's GI Santa Anita Derby, each worked Sunday. Intrepido, trained by Jeff Mullins, worked a half-mile under jockey Hector Berrios. Robusta, trained by Doug O'Neill, drilled six furlongs with jockey Emisael Jaramillo in the irons.Intrepido was officially clocked working four furlongs in :47.60. That time was quite a bit faster than what trainer Jeff Mullins had on his stopwatch.“Way off,” Mullins said. “I had him in :50. A bunch of us up there had him in :50.”Whatever the case, Intrepido appeared to have cooled out well following the work. The colt will try and provide Mullins with his fourth win in the Santa Anita Derby while also securing a spot in the Kentucky Derby on May 2 at Churchill Downs.Robusta was timed going six furlongs in 1:14.2. A homebred for Calumet Farm, the colt most recently finished second by just a head at odds of 67-1 in the GII San Felipe going 1 1/16 miles on Mar. 7.Intrepido is owned by Dutch Girl Holdings and Irving Ventures. In his only start this year, Intrepido finished second by three-quarters of a length in the GIII Robert B. Lewis going one mile.As a 2-year-old, Intrepido won the GI American Pharoah going 1 1/16 miles at Santa Anita. He closed out the campaign by finishing fifth in the GI Breeders' Cup Juvenile after being compromised by a slow start.The post Santa Anita Derby Contenders Intrepido, Robusta Work appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
