Dr. Schivel, a 2-year-old son of Violence who has run in the money in each of his four starts, will take off the rest of the year.
The Daily Racing Form reports that the colt will return for a 3-year-old campaign next year.
New trainer Mark Glatt told the DRF that the horse has not been injured, and that he'll get a 90-day rest after "quite a few hard races."
Dr. Schivel debuted with a third-place finish in a maiden special weight race at Santa Anita in June. Then he finished second in a maiden special weight at Los Alamitos in July and graduated at Del Mar in August.
After breaking his maiden, he was bought by a partnership of Jed Cohen's Red Baron's Barn LLC, his son Tim Cohen's Rancho Temescal LLC, William Branch and Dean Reeves, according to the DRF report.
Last out, he won the Grade 1 Del Mar Futurity on Sept. 7 by 1 3/4 lengths over Spielberg.
After that race, the colt was transferred to Glatt from Luis Mendez, who trains for the Cohens, according to the DRF report.
