DEL MAR, Calif. -- As the purgatory in which jockey Tyler Baze finds himself this summer at Del Mar grinds on into a second week, his agent, Jack Carava, on Friday said they may opt to not be named on horses until Baze can clear a required drug test for a medication that has lingered and kept him off mounts. On Friday, Baze for the sixth straight racing day could not pass a test for the medication, and was taken off his four mounts. He has shown up every day expecting to ride, but until the medication clears he cannot ride horses in the afternoon or even the morning. Stewards have allowed Baze to go to the stable area so he can at least see horsemen, which Carava said would at least be reassuring as to his health. But Carava said continuing to accept mounts and not be able to honor them might not be the best policy, since there's no clear-cut end to something they thought would be over last week, let alone this week. :: Visit the Del Mar Handicapping Store for Past Performances, Clocker Reports, Picks, Betting Strategies and more. Baze on Aug. 15 was given a medication when his blood pressure temporarily spiked, owing to stress or anxiety. He does not have chronic hypertension. He was given a drug that acts fast to becalm a person. But Baze cannot have even a trace of that medication in his system in order to get on horses. The doctor who gave him the medication that day said it would be gone in one to three days -- in time for him to resume riding, in theory, on Aug. 18 -- but there are instances where the medication has stayed in a person's system long past that timeline, and Baze apparently is one of those outliers. "He got a second opinion,” Carava said Friday afternoon. “That doctor said because he's so fit, eats so well, and is so lean, his body is trying to hold on to anything. At least he can go to the stable area. Getting in front of trainers so they can see he's well is important. But I'm not sure if taking calls and putting him on horses and having to take him off is fair at this point. We'll have to see." The next day for which entries will be taken is Saturday, for the Thursday, Sept. 1 card. Baze has not ridden now for the past 10 racing days. He initially took off the cards from Aug. 11-14 to deal with what stewards deemed "personal matters" with his family. Baze has been a mainstay on this circuit for more than 20 years, beginning when he won the Eclipse Award as champion apprentice. He is popular with trainers because of a work ethic that finds him breezing numerous horses every morning, but all that is on hiatus for now, with no definitive end in sight. It could be tomorrow, but they've been hoping for that for more than a week, and nothing has changed.
