Mackinnon won his stakes debut in the Del Mar Juvenile Turf on Sept. 6 and could have his next start in the Breeders’ Cup Juvenile Turf on Nov. 5 at Del Mar.
Trainer Doug O’Neill said forthcoming workouts will determine whether Mackinnon starts in the $200,000 Zuma Beach Stakes at a mile on turf on Oct. 3 at Santa Anita or is trained toward the BC Juvenile Turf.
“We’ve got options,” O’Neill said. “The more time in between races the better. It’s a strong temptation to wait, but if he’s coming out of his skin we’ll have to consider” the Zuma Beach.
