LOUISVILLE, Ky. – In the aftermath of another eventful Kentucky Derby, a large field is taking shape for the final leg of the 2020 Triple Crown, the Oct. 3 Preakness at Pimlico. Authentic, winner of the Kentucky Derby on Saturday, is foremost on a list of at least 15 3-year-olds deemed anywhere from definite to possible to contest the $1 million race at the historic Baltimore track. The connections of the Derby runner-up, Tiz the Law, are mulling whether to run in the Preakness or wait instead for the Nov. 7 Breeders’ Cup Classic at Keeneland. Unlike in most years, when a possible Triple Crown sweep is in play when the Preakness is run in mid-May, there is no such chance this time after the race was postponed from its original May 16 date owing to the ongoing pandemic. The Belmont Stakes was won June 20 by Tiz the Law, whose Triple Crown chances ended when he ran second Saturday as the odds-on favorite at Churchill Downs. Authentic and his Bob Baffert stablemate Thousand Words will train to the Preakness out of the Churchill barn of D. Wayne Lukas. Baffert said Authentic initially was scheduled to return shortly after the Derby to his California base, but “being that the Preakness is just a few weeks away, I thought it might be a little too hard for him to go back.” Barclay Tagg, trainer of Tiz the Law, expressed serious doubt in the immediate aftermath of the Derby about running in the Preakness, but Jack Knowlton, who manages the colt’s owner, Sackatoga Stable, said Sunday he would prefer to run while leaving the final decision to Tagg. “My thinking is that we will, but we’ll have the horse dictate what’s going to happen,” Knowlton said. :: Click to learn about our DRF's Free Past Performance program. Tiz the Law was scheduled to return Tuesday to Tagg’s barn at Belmont Park in New York. Four horses who did not get to run in the Derby are among the likely Preakness runners, led by Art Collector, who already has returned to training after missing the Derby with an ill-timed nick of his left front hoof. The other three were scratched off the Derby program – Thousand Words, King Guillermo, and Finnick the Fierce. Thousand Words flipped and fell prior to being saddled in the Churchill paddock, leading to an automatic scratch under Kentucky rules, but “didn’t have a scratch on him” from the incident and is all set to resume training, Baffert said. King Guillermo, who was declared Thursday from the Derby with a fever, will continue to train at Churchill until shipping to Maryland about a week before the Preakness, trainer Juan Avila said Monday through an interpreter. Finnick the Fierce, who scratched Friday after trainer Rey Hernandez said a state veterinarian believed the one-eyed gelding “was a little off in his training,” has returned to the Thoroughbred Training Center in Lexington. Others likely for the 145th Preakness are Mystic Guide and Liveyourbeastlife, the respective one-two finishers in the Jim Dandy on Saturday at Saratoga (with the latter requiring a supplemental payment to be eligible); Pneumatic, winner of the Aug. 15 Pegasus at Monmouth Park for Steve Asmussen; and Lebda, a back-to-back stakes winner at Laurel Park earlier in the year. Possibilities include Mr. Big News, third at 46-1 in the Derby; Happy Saver, who was the heavy program favorite Monday at Laurel for Todd Pletcher in the Tesio Stakes, a Win and You’re In qualifier toward the Preakness; and Mongolian Wind, who also was scheduled to race Monday at his home track, Assiniboia Downs in Canada. Dr Post, fourth as the 3-4 favorite in the Jim Dandy for Pletcher, and Azul Coast, a third Baffert horse, also are listed as possible for the race by Pimlico officials. Only as many as 14 can start in the 1 3/16-mile Preakness. This will be the second straight year a Triple Crown sweep is not possible when the Preakness is run. Country House was not entered in the 2019 running after winning the Derby by disqualification; he has since been retired without another start. Before that, the 1996 Preakness was the most recent renewal missing the Derby winner, that being Grindstone, who was injured and retired. As a side angle that has little to do with the Preakness, Authentic is now eligible for a $1 million bonus being awarded this year by Monmouth Park for a sweep of the Haskell, Kentucky Derby, and Breeders’ Cup Classic.
